Venomous snakes and poisonous spiders in Brazil

Like nearly every country around the globe, Brazil does have more than its fair share of deadly assorted nasty insects and venomous spiders and snakes. Always pack anti-histamines when you go abroad as you never know when you will need them. Here are some of Brazil's nasty biting and stinging animals, these are only a few out of the hundreds that are in Brazil which may be met whilst on vacation.


There are many different snakes found in Brazil, some are harmless, and some can get a bit nasty if cornered. Most of the snakes belong to the viper family, which do give a venomous bite causing inflammation of the bitten area and severe pain.The Pit Viper mainly feeds on birds but will bite humans if agitated. Another viper found in Brazil is the Tree Viper, green in colour, which makes it difficult to spot, and again can and will bite, so if you have had a few drinks and feel like climbing something, select a lamp post instead of a tree, you never know what is lurking in the branches. Many vacations to Brazil have been plagued by snakes and insects.

The Bushmaster Snake can reach 3 meters in length and is usually found in the Northern regions of Brazil. Very scary to look at if you came across one of these, but do not forget, this is the Brazilian Rain Forest Country with the Amazon River flowing through it. There are many thousands of different species of animals, snakes, spiders, and insects that will want to taste your blood, be warned and be prepared. When you arrive, find the local pharmacy and hospital in case of an emergency, always be prepared.

Whilst on vacation packages to Brazil, always stay within the boundaries specified by the tour group, it is for your own safety.

The Rattle Snake, much feared in many western films, has also made Brazil its home. With the distinct rattler on the end of it's tail, these are hard not to distinguish, and can also grow up to three meters in length. The bites are usually not poisonous, but are very venomous, if you see one of these beautiful snakes whilst on vacation or holiday run like the wind, if you get bitten by one, hop as fast as possible to a medical centre or hospital, you will need an injection and anti-histamines.

Coral Snakes are also common in Brazil, they may sound nice and flowery, but they are not, these are actually poisonous and very deadly, keep away at all times. If you do come across one in your house or room, get some help from staff, they will know how to deal with it. Do not play with it, even with a stick, they can be very fast, if you of your family are bitten by one of these, go to hospital as fast as you can you life and vacation depend on it.

Brazilian Wandering Spider

The Brazilian Wandering Spider is classed as the worlds most venomous spider. Their bodies can be up to 5cm in length, then add on the legs and you have a dangerous 15cm spider, approximately, they can be smaller, but have also known to be bigger, that is a big spider, with legs this big, it must be very fast. These spiders do not have webs and they walk around the floor at night hunting for food. Like scorpions, they will rest in the daytime under rocks and anything else on the ground, including shoes, slippers, and hats.

A bite from this Brazilian beauty, can make men impotent and usually give a man an erection ?? Although the erections can last for several hours, they will also be very painful, you cannot have it both ways. There are different sub species of the Wandering Spider, one of these species, one spider, killed two children at the same time, in Brazil. Be warned.

There are Black Widows and the Brown Recluse Spiders in Brazil, and these two groups are responsible for most of the spider bites in Brazil, causing much discomfort and in certain circumstances, hospitalisation. If in any doubt about a bite or a sting, seek medical attention immediately, don't say it can wait till later, you may be dead.

The Brown Recluse Spider bite can leave a huge 20cm gaping hole on a human.

Online deals for vacations to Brazil should also come with a warning on the poisonous snakes and spiders which are in the area.

      I am Brazilian and I can guarantee that in 33 years so do not know a person who has been bitten by a snake or a spider. I know that animals are dangerous but bites are rare. In the United States more people die of snake bite. Not forgetting the black widow.

      I just came home from brazil with what i thought was a nasty burse. It turned out to be some kind of bug bite, very infectious, kept spreading and then causing pain. I needed lanceing and major aniibiotics. But I do not know what bit me.

      I'm not really sure. But I do know this: Next time you get your bananas shipped from Brazil, check for the 15 centimeter beasts before they find you. They really like bananas... No joke.

      The Brazilian Wandering Spider is described by "some" as the most venomous or poisoness spider in the world...however, most experts say its the Sydney Funnel Web Spider that is the most venomous. Which is true???
