Black Widow Spider Facts

Black Widow Spider Female

Characteristics

An adult black widow spider has a black shiny abdomen, with two red triangles underneath, the shape of an hourglass. It is very small about 1.5 cm not including the legs.

These spiders make their webs usually outside and in dark places. The web is often built close to the ground, near houses, or in garages.

Females lay about 300 to 400 eggs per cocoon, and about four cocoon's every summer.

The black widow spider is nocturnal, it hunts and moves about at night. It is a very dangerous spider. In fact its venom is 15 times more dangerous than that of a rattlesnake.

It is an invertebrate animal belonging to the arachnid family, to the class of the arthropods. We can count 8 to 10 species. Its bite can paralyze, even kill.

the Black widow spider female is about 15 mm, the male is smaller only about 7 mm. It has two eyes above the mouth and two hooks with which it injects its venom.


Bites Look Like This

The black widow spider bite

Reaction to a black widow spider bite, depends entirely on where the person was bitten. The venom of a black widow spider is particularly dangerous, because one cannot feel the bite when it occurs, and when the person discovers it, it is can already be infected. The bite is normally sensitive 48 hours after it occurs.

Symptoms of the black widow spider's bite are frequently fainting spells, difficulties in breathing and speaking, vomiting, a low pulse rate, and a cold body. These symptoms can last 4 to 5 hours before falling into a coma, and if no medical care is available death could ensue. The majority of people who have been bitten by a black widow spider have not died, but spent 2 to 5 agonizing days before recovering completely.

If you have been bitten by a black widow spider, stay calm, catch the spider if possible, to make sure it is identified by a specialist. Call a doctor or a hospital right away. We recommend that you apply an antiseptic lotion if you can.

Children under the age of 16 and older people over 60, and people with cardiac problems will probably have to remain in the hospital for a while.

Another Look At The Spider

More facts about black widow spiders

A black widow spider lives about 1 1/2 year. The male has a shorter longevity, only eight months maximum.

The black widow spider is an insectivore. It is found in tropical regions, in the United States, in Australia, and in several countries in Europe. It likes dry and grassy grounds.

Only the female is dangerous, it is recognizable to its bright spots under its belly. The most dangerous for humans is the American black widow spider. (Latrodectus mactans).

Generally, man is not on the spider's menu. About 15 species are dangerous, but bites leading to death are rare.

The silk that the black widow spider spin for its web is extremely strong. The threads of the web lay in a crisscross pattern making it a deadly landing for any insect. When an insect land on it the spider which was waiting for a prey in the center of the web, will feel the vibrations and rush towards the unfortunate victim. It will spin it on itself wrapping it in a silk coffin; there is no escape possible, as this spider is a feared hunter.


Black Widow Web

Black widows spider have redeeming value

Lest you should believe that such a dangerous little animal is rather worthless to human, it has its redeeming value.

A few years ago scientists in Chile isolated properties in the black widow spider's venom, that according to their study could treat naturally and without side effect, erectile disfunction. The drug has been tested on animals and reports say that it functions pretty much as would Viagra.

It would seem that the Chilean spider, offer a venom rich in possibilities as the scientists are reporting that it might have spermicidal properties. These properties do not seem to be present in the venom of black widows in other regions of the globe, said Chilean Dr Fernando Romero, head of the project.

Working for the Universidad de la Frontera Dr Romero has applied for a patent for his discoveries.

In 2007, another team of scientists at the University of California in the United States, have identified two major genes in the silk from the black widow spider. The properties of this silk, elasticity, resistance and lightness, would make it a good candidate for usage in such materials such as bullet proof jackets, and medical applications. Industrial production can be done by adding these genes to a bacteria which can synthesize the protein. The University has filed a patent application for an industrial application.

I personally like spiders. They are like "dog in a cage" ... they sit in a corner catching "wandering" insects. From my experience they make one web and sit there. They never seem to bother me and I do the same. I have never encountered a black widow spider though ... I am not sure what I would do in that case.

Good you did have to panic since it was dead. It probably would not have hurt you, the important is to see it. It is when people do not see them and disturb it by accident that they can get bitten. Thank you for your comment

Mireille G 7 years ago from Kansas Author

Well you are helping the black widow and that is commendable but what about the poor creatures you threw there. I tend to think that if the widow want to catch them she is capable on her own and we should let nature take care of itself. I am all for feeding the hungry, but not really willing to perform sacrifices. LOL

Yes it is a mean spider not sure I would use the wording you use for it. It is a little insulting to female dogs. :)

Thanks for stopping by.

If you catch a black widow and want to kill and mount it for a bug collection -- is it safe to do that or can you easily have venom injected into you while handling the dead black widow?


Mireille G profile image

Mireille G 7 years ago from Kansas Author

It is not safe to handle a black widow spider. I would consult with a bug specialist at your local university on the best way to do that. But I do not recommend that someone inexperienced tries it. This is a very fast spider. You would not die from a bite, but it is very unpleasant and you will have to seek medical help. Please don't do that.

I think that if the spider is dead and you handle it carefully you will be alright.

Spiders terrify me and it is 100% irrational. I am a total arachnophobe. No other insect really bothers me in the same way. I would literally rather have to fight off a rabid dog than be anywhere near a spider. However, they do eat annoying flies and mosquitoes! So, besides my irrational fears, I will still give spiders their few dues.

I just saw a black widow in my garage, i sat down next to the web and watched it for 10 mins or so. This little beetle looking bug was in her web and I was lucky enough to get to see her spin him up! It was really awesome I felt like I was watching planet earth or something.

Ello 6 years ago

Hi Mireille,

About 6 months ago I found a little spider making a web under the lip of my bathtub in the corner near the floor. There was a little hole that it could escape to if disturbed. At the time I thought this is cool even though it was in my bathroom. So this may seem a little macabre but I started to actually get a little attached to it…weird huh?! Everyday a random fly would enter my home I would stun it and feed it to the spider, not knowing what kind of spider it was. Yesterday I found out by doing some research that it is a Black Widow and so now I am freaked out a wee bit. My friend said I should kill it but I can't do that, I want to trap it and transplant it somewhere far away. I am stuck and also since it is a little cooler here in LA she is staying kind of hidden away. I think she is anticipating me catching her:) Anyway any advise on what to do?

Also question for you do these spiders ever leave their web at night to look for food? I keep having thoughts of this spider walking through my living room:)

Help!


Mireille G profile image

Mireille G 6 years ago from Kansas Author

@Ello,

I would not worry about the spider walking through the living room at night then returning to the web during the day waiting for you to trap it. They do use their web to catch food, so it stands to reason that it would stay there if it has a web.

I am puzzled by the length of time this has been going on. I probably would not have lasted 6 months with it. :)

By the way they can live about 3 years in the wild, so with you making it a pet and feeding it you might have it a long time unless you catch it and get rid of it. Killing it is not the end of the world. It is a spider.


Ello 6 years ago

Thanks Mireille you put my mind at ease I know it sounds ridiculous to have this spider in my bathroom for so long. I just didn't mind it cause it was quite small 6 months ago and I found it so interesting to watch. I even clean up after it bizarre I know, it is after all in my bathroom. OMG I sound nuts :) Anyway I have some guys coming over tomorrow to do some work on my apartment so I am going to ask them to catch her and then I will release her somewhere dark and moist where she can live out her life and maybe I can get back to normal around here.

Hi, Mireille....

I was checking this hub for the info needed to recognize a black widow spider, but I'm a little leery now. Seems that some of you have them for pets. Not so sure about Ello. I guess it is whatever floats your boat. For my part, I'm going to kill the spider outside my door, black widow or not.


Ello 6 years ago

Hi Mireille.

Mission accomplished I could not go another day without taking action. I finally caught her and took her to a new home far from me. In the future I will have to abstain from keeping Black Widows as pets it's just not a good idea :)

Mireille G 6 years ago from Kansas Author

Ello, you did it! Good for you. If you feel lonely I have a kid I might sell LOL, I would not give her away for anything in the world, but I might suggest you get a real pet. If you need something really cute and gentle and quiet and easy to keep, look at hamsters.

We had one and I grew fond of her.

Best to you.


IreneH. 6 years ago

Okay, I'm starting to be scared of this. But very helpful information. Don't black widow spiders build their webs or homes in dry places? Or is that outside? Anyways, I feel more alert in my house. Either in my bathroom, bedroom, or kitchen. Afraid to see a black widow spider. Even though, I live in N.Y. Should I watch out for it?


Mireille G profile image

Mireille G 6 years ago from Kansas Author

Irene, I don't want to scare you and for the most part you may never have a black widow spider in your home, but yes they can enter, I had one in the house in NC. Usually they are not as common as the brown recluse in homes and are mostly found outside. In a house if there is one it will be under heavy furniture or appliances. To control all spiders a good cleaning once in a while in these out of reach places is not a bad idea.


zabella 6 years ago

Great info here! I respect these critters, and whenever I find them around my house or shed, I re-locate them. I have noticed one under the eves of my house. I'm cool with that; she stays in her web and is eating a lot of insects, but there are some egg cases there. Does the mother spider eat the babies, do they take off after they hatch, or am I going to end up having 400 BW spiderlings soon??


Mireille G profile image

Mireille G 6 years ago from Kansas Author

The hatchlings will hatch within the cocoon and will leave the web as do other spiders.

Lauren 6 years ago

Last night I saw a black widow, in person, for the first time. We have a table and chair set on our front porch, and my husband and I sit out there every night watching the kids play in the yard. I have been noticing a spider web from the chair I always sit in to the the house. For the past 4 days I have knocked the web down and cleaned it up....then the next day it is back. I walked out on the front porch last night around 10 and finally saw the culprit. As soon as I got close enough I could identify immediately that this was a female black widow. I yelled for my husband to bring the bug spray so we could kill it. They are very fiesty for sure...did not want to die right away. It tried to crawl around for about 3 minutes before it finally gave up. Now I am freaked out to say the least knowing that these things are around our home. I had been sitting on top of it for at least a week, and never even knew it!!!!!

I just saw (and killed) my first black widow spider. I was out of town for a few days, and it had built a massive web in my doorway. And it was just chilling in the web. It was beautiful, but I couldn't let it live. I wouldn't have been able to get past it and into my house!

And I gotta say. I'm a little freaked. I see brown recluses all the time. But black widows are so much scarier looking!


mobatgirl 6 years ago

there is a large female in captivity and a few of us are enjoying her beauty (through a clear glass jar, tightly capped). We are opening her jar once a day for air, and have been feeding her crickets. She fascinating to watch. When first discovered, and incarcerated, what may have been the dessicated remains of her mate were in the web. So now we wonder if she has mated. Of course this is a torturous situation, as we are just observing and do not really intend to let her go...though as we grow more attached and entranced, we may take her out to the woods somewhere. Do you know of any websites with info for dietary needs?


Mireille G profile image

Mireille G 6 years ago from Kansas Author

@mobatgirl thank you for your comment. I am sure she is fascinating to watch but I wish you would turn her lose. She does need to catch her prey to be happy, (if a spider can be happy). As you get attached you probably want her to live as long as she can. Turning her loose is the best thing you can do for her.

Wishing you well.

Is the strength of black widow silk unique to black widows, or do all spiders have silk that is equally strong? I remember always hearing that spider silk is stronger than steel, but I've never heard it applied uniquely to black widows.

I have a phobia of spiders, maybe because I lived with them in my basement bedroom growing up. People that like spiders live in a universe I cannot fathom. Isn't it true that the female black widow eats the male after mating, or is that just a story made to scare little kids living in basements?

My brother was keeping a female black widow spider in what he thought was a spider proof container, and she had laid her 3 sacks of eggs, and when they started coming out of the sack, he promptly realized it was not spider proof and he got rid of the spider, however I am led to believe that some of the babies were still in my house. I am pretty sure I saw one in the bedroom today, where he had the container, what should I do. I was thinking abut bombing the room, or should I do the whole house?

These things scare the crap out of me. Especially with a toddler and a small dog in the house. Last summer I found one on the corner of our french doors leading out to the backyard. I thought it was weird because that area of the door gets a lot of sunlight through out the whole day, and I thought they like dark areas. Then when we took the pool down a few weeks ago, my nephew spotted another one. So, creppy. But I read something about the black widows living in clusters? Is this true? Should I be expecting more visitors? If so, what is the best way to get rid of them? By the way, I WD-40'd the one on the doors, and my nephew stepped on the one by the pool, but if there's going to be more of them I need to figure out what to do with my daughter and dog always out in the backyard.

Gypsy Jan 5 years ago

Here in the central coast of California we have them all over the place. One year I found a nest under a porch chair and extracted the female intact and kept her in a large jar with twigs. I fed her crickets from the pet store and let all the children watch her for a couple of weeks. Then one morning she looked really small. Low and behold she had laid a cocoon of eggs. After all the kids got to see the egg sack I killed them all with Raid. I don't like killing them but did it anyway. It was a real education for the kids who are now able to identify them and keep their distance.

I have been workijng at this house and seen the Widow in the corner of the window of the basement . I'm not real scared of spriders it's mostly the web that freaks me out . we seen that she had one egg . Three days later she had another egg . Was going to killer her , thought about it then was going to killer her and put in a jar . No could'nt do it . I have seen these widows before but this is the biggest I've ever seen . I damaged her eggs feel bad for it . but I now have her in a small jar with her eggs didn't want her heart broke . Any how now what do I do with her ? Thought of giving her to the Zoo or something . But don't want to let go of her she is so amazingly beautiful . She has an hour glass on her tummy that is almost like the shape of hearts , then a strip that goes toward her rear , with another big red dot .

Sarah 5 years ago

Hello! Thanks for the info, very intersting. Last month I noticed a Black Widow living outside of my kitchen window. She was living behind the shutter attached to the wall. I would only see her at night. I couldn't kill her and I wouldn't let my boyfriend kill her either. My plan was to move her. Over the time she was here, I noticed her changing some. This sounds like a silly question, but do spiders look different when they are about to have babies? We ended up moving her last week, but this afternoon I noticed lots of little babies right outside of where she was staying. I am assuming they are hers, but is there anyway to tell? Not sure if I can move a bunch of babies but maybe hose them away. I hate to kill things, especially things that are smaller then me. I always feel that if they can be moved safely, why kill them? Silly I know. I really think they are hers, but I guess the question is, do spiders look different before having babies & how do I know if they are black widows when they are so tiny? Thanks!


Really old man 5 years ago

Don't put a black widow or any spider in an insect collection because they are not insects - they are arachnids. They have eight legs and only two main body parts while insects have six legs and three main body parts. Almost all, if not all, spiders produce venom, but most won't or can't bite you (the mandibles or jaws are too week to penetrate skin). In the United States there are only a few that can bite you (namely the black widow, the wood recluse or fiddle back, the tarantula, and the giant wolf spider), but only the black widow and wood recluse have venom that will harm you. It is really difficult to get a tarantula or wolf spider to bite you, but I have been bitten by both kinds when rescuing them from children with sticks. The tarantula's bite is very similar to a wasp's sting as is the wolf spider's but a little numbness follows the initial pain. I taught science for thirty years before I retired and did field studies during most summers. I would strongly advise against keeping a spider for a pet, especially a black widow. Many people keep tarantulas as pets without realizing that a male tarantula will live about five years while a female tarantula can live for thirty-two years! Once they have been kept in captivity for a length of time, they lose the ability to hunt on their own. If you turn them out then, they are apt to starve. All spiders are beneficial to humans so I, personally, tolerate them where ever I find them - in my house or out. The black widow, however, I kill as soon as I find one. The wood recluse is the more common of the two spiders being present in almost all buildings including all those occupied by humans. Before you have you home or office sprayed for wood recluse spiders, be aware that the residual spray will do you more harm than the spider's bite and you will be killing other harmless-but-helpful spiders.


Carol R. Riley 5 years ago

I have black widows in my backyard, in the garage. Which I try and kill every chance I get. I have a question: the newly hatched black widows, are they a white color? and do they have the same amount of venom as a full grown spider?


scaredycat 5 years ago

if a black widow falls in a pool but is still alive, and i take it out and kill it... would the black widow could have sprayed it in the pool??? I need to know fast.


Really old man 5 years ago

scaredycat, the black widow does not spray out her venom; she injects it. Even if she were able to spray out her venom, it would amount to a tiny drop and would be immediately diluted by the water. I don't believe you have anything to fear from the water in the pool or (if you killed it) the black widow. If this is a wading pool or a swimming pool, you would probably have a great deal more risk from the inevitable urine in the pool. :-)

Mr D 5 years ago

I just woke up & Think i saw a black widow above my head i shit myself & Jumped up. It got off the bed by the pillows, Is this possible?


Really old man 5 years ago

Mr. D., I suppose if one were to get really excited suddenly, then one might very well shit one's self. Having done that I should think that jumping up would be only natural - rather messy, but natural. As to the likelihood of the black spider having been a black widow, I rather doubt it. It is not impossible, of course. However, it is much more likely that the black spider on your bedroom ceiling was one of the jumping spiders (Salticidae) such as a bold jumping spider (Phidippus audax). The male bold jumping spider is black with varying amounts of white -some with almost no white- on their legs and body. These are hairy spiders grow to be half-an-inch in size and frequently move indoors during early fall through winter. They make my wife uncomfortable, but they are very good at taking care of the insects and other invertebrates that also move indoors about the same time. They are especially good at catching flies. We always keep bananas in the kitchen and there are the attending fruit flies. Once we get a bold jumping spider in the house, there are no more fruit flies. The bold jumping spiders and their kin are not a threat to humans other than perhaps startling a person. :-)

Sorry it wasn't on the roof, It was above my head E.G when i got up off the bed i saw it! It was by my head the whole time. I'm familiar with black widows i've only saw pictures of them mind ya! LOL. I got really worried has i know they are poisionious & Their venom is 15 times stronger than a rattlesnake. I also have a baby girl who's 4 months!I soon got the missus & Baby to sleep in the front. It defo had two red marks on the back, But it wasn't really fat as black widows are!


Really old man 5 years ago

Mr. D., If the spider you saw was not hairy and was glossy black with red marks on it, it very well could have been a black widow. If there was not web (a black widow's web is not a neat, tidy web), then the spider was moving to a new location and not a resident. Now, a black widow does not have to have a web or be on its web to bite someone. So, just because it may have been a transient does not mean you do not need to be careful. You certainly want to protect your four-month-old girl from the black widow, for a young child or an elderly person are the most at risk of the bite being fatal. I'm not suggesting you allow your wife or yourself to be bitten either.

Their venom is much stronger than the venom of the most poisonous of the rattlesnakes. While you are remembering this fact, remember also that most rattlesnake bites are not fatal. Indeed, if a black widow injected you with as much venom as a western diamondback rattlesnake (Crotalus atrox), an eastern diamondback rattlesnake (Crotalus adamanteus), or a Mojave rattlesnake (Crotalus scutulatus) -the three rattlesnakes with the most dangerous venom- then you would almost certainly die. However, remember also that the black widow is injecting a very tiny drop of venom designed to kill an insect similar in size to the spider itself or smaller. Admittedly, that is more venom than I want in me but not reason to move to another house. Be cautious, be wary, be careful and, if you see the spider again, smash it just to be on the safe side.

I'm trying to find close-up pictures of what the mouth of a black widow spider looks like. Making a giant spider on my lawn out of PVC for Halloween.

Thanks, Janice M.

Have had a Black Widow for several months as a pet. I keep her in a jar and feed her roaches and crickets. I understand many people are quite scared of spiders but me and my kids love watching her feed. They are very amazing predators. I am glad to hear she could live 3+ years.

I've handled a black widow before. As long as you remain calm and don't squeeze her she is calm.

When I was a kid back in the early 70's in central California I caught several in a large mason jar and hid them in my closet, then one night I forgot to put them up and my mom coming home from work discovered the jar on the table, needless to say she wore my butt out with a wooden spoon LOL kept asking me if I lost my mind!

I recently bought a home in southern AZ. I know black widow spiders are common here, and had a frightening experience with one getting way too close to my 2 yr old. I sucked the spider into the vacuum and dumped her in the toilet. Then called the exterminator to spray for spiders etc. Should I still be worried that there are more venomous spiders in my yard?


julian black 4 years ago

Widows arent that bad, most people think they are the most dangerous thing on earth. When I was a kid i heard stories of them killing people in 3 hrs and ridiculous things as such. the reality is that 98% of bites arent fatal and that tiny 2 percent are elderly, infants and people who are allergic to the bites. The bites do suck but you could get bitten by one and just suffer the fever like symptoms, ive been bitten by them a couple times and never really worried too much about it.


julian black 4 years ago

That being said im not saying you shouldn't go to the doctors, because everyone's body is different and deals with the effects of the venom differently, the doctor can tell you how your body is reacting to it, and make your symptoms a lot easier to deal with.

This is going to sound a LITTLE odd. My husband found a black widow yesterday and knows I hate spiders. He put it in a jar and left it on the counter. I got home and freaked out. I put some water in the jar and ran away from the spider. I know it sounds stupid I hate black widows. I woke up this morning to dump out the glass and the spider and the spider had turned white and disintegrated. It was still intact but it was see-through. Really odd. WHY??

they aren't harmful as long as you treat them carefully.

Like what they say:

They are more scared of you than you are scared of them.

I saw an episode of 1000 Ways to Die and this dude let a BW bite him because he thought he was immune to the venom, and well as the name implies... he died. I personally think this show is full of shit. Any of the symptoms would make him call 911.


Patty 4 years ago

We have SO MANY of them on or small property. I hate to kill them but my elderly mother putters around the yard and there isn't a safe spot to be if shes around pine straw, our shed, etc. I captured one this morning and her egg sac plus one that had already "hatched" it's young. If I thought someone would like to have them I could start a roundup!

Shannon07 4 years ago

We just discovered we have at least 4 huge ones living on our porch.. We killed one already. I'm now super worried about egg sacs hatching : / we are letting the property manager know tomorrow!! Especially seeing as my boyfriend is still recovering from a spider bite from almost a month ago!! I check our room every night now.

Boy, that spider silk is so strong..yes, only the black widow spider has the stronger web(in the USA), as the individual strands of spider silk are actually thicker than that of most other spiders. To the unfortunate insect or insects, the web strands to them would look like angel hair pasta with an ordinary spider, but probably would be as thick as regular string, possibly all the way up to thick string to the insect!!! If these widows were the size of your hand, you are looking at web strands that would probably be as thick, or almost as thick as sewing thread, already getting dangerous to a human on being ensnared, and dangerous to a large bird like a pigeon. The size of the one on Lord of the Rings? Forget it!!! That freaking web strands would be as thick as string, probably even thick string!!!! Spider silk is so strong, that a large web with strands just as thick as angel hair pasta would be dangerous to man.

I did have 3 black widows in my garage. My Xbox is currently in there so I spend some time in there. One of them was ground level 5 feet from me on my right and another above me to my right, then one far left.

They did not mess with me so I left them alone until the one on my right came down to eye level. I did not notice it until I went to reach for my cup. It was bigger then the other 2.

So sadly I had to kill it and the others about a week later a new spider came it was also a black widow, it was way bigger then the other 3. So my brother decides to shoot it with one of those BB guns and its ass like explode.

IT IS STILL ALIVE.... I found it on my door with no ass... I went to kill it and it ran... PLZZ tell me it will die soon....
