- Eliminating Pests
Rid Your Home of Black Widow Spiders
Our black widow house invasion took about 18 months to unfold. Two reasons made your house ready for the population explosion.
First, our carpets were removed and we installed engineered wood and we started seeing silverfish. The suggestions on the internet were of no help, and no whole scale eradication was done. These bugs were in every corner and cabinet and most likely became the black widow's food.
Second, the black widows were outside of the house for the past two years in alarming quantities. Control of the areas we frequent during the day were sprayed at night, when the spiders are more visible under a flashlight.
At the same time, I started to see white spots and webs under the new wood lip of the dining room step. The reappearing webs, thought of, as the work of a "house" spider.
What Happen Next?
We had the silverfish as food for the spiders in the house and we ignored the white spots. In a few months we had more spider evidence than was acceptable.
We were using boric acid for the silver fish and started to see less and less of them. I am glad for that, because silver fish are very creepy. We are sure the widows helped us with that task. We also had no ceiling webs from house spiders either, for months, also the work of black widows.
So how were we to rid the house of scary black widow spiders?
A Plan for Killing Black Widows Spiders
Time required: Two months
Cost: Less than $10.00
- Can of Raid roach killer
- Spray cleaner
- Shop Vac or house vacuum
1. Be aware of white spots in corners or under tables and chairs. If the spots look like these pinhead sized spics you may have a Black Widow in the house.
Do not ignore.
2. Look under every piece of furniture in the affected area.
This is an entire spider trail used over and over again. Found under a wall unit which was completely closed to view from the front.
3. The white web trail is the black widow's highway. You will also find egg sacs: white balls completely spin with filaments. If you see any black spiders or smaller brown juveniles use Raid and a strong vac to clean everyone out of the area.
Clean all white spots in every area to be able to see if such evidence reappears.
4. This spot is where our problem started about 18 months ago. I continued to clean white dots and wipe away webs. This month we inspected under the rounded lip and saw open cracks that allow a spider to hide. Black widows will run rather than be seen.
We have used clear silicone to seal the cracks and I see no more evidence at this spot.
Update: Feb. 2016. No black widows in the house or a few years. The homeowner's are now both retired and do have more time to keep the home in better order. Jobs are a toll on home care, but are very necessary. Be sure to go to the Internet for possible solutions, someone else has surely gone through the same thing and is willing to tell about it.
Hope this was of help to you.
Homeowners need to alert be to avoid such a black widow infestation. Those white spots are an important clue for unwanted spiders.
Second, the Raid does not have any lasting effect. It is only good for the "first kill". Any new spiders that walk in the area will not be affected. Visualness and attention is the key for keeping unwanted venomous spiders out of your house.
