The black widow’s venom is highly toxic. It is reported to be 15 times more toxic than the venom of a prairie rattlesnake. Even though only a tiny quantity of venom is injected with each bite, reactions to the venom can be quite severe.

Children and the elderly are more at risk for adverse reactions to the black widow’s venom. You could find black widow spiders in and around undisturbed areas, woodpiles, meter boxes, outdoor toilets, and under eaves.

The severity of your reaction to a black widow spider’s bite depends on the area of the body bitten, the depth of the bite, the amount of venom injected, your age and other factors.

Most spiders aren’t aggressive, and bites usually occur accidentally.

Spider Bite Prevention in Texas

Prevention is the most optimal treatment of all for poisonous spider bites. You can choose between chemical and non-chemical spider controls to reduce the risk of being bitten by spiders.

You can control spiders by introducing non-chemical measures. A simple way to keep spiders away is to reduce bright outdoor lighting that attracts bugs and insects. Since spiders feed on insects, more light attracts them, resulting in more spiders. Reduce the spiders’ food supply, and you will reduce the number of spiders.

Exclusion is an effective spider control measure. Caulk or seal outside openings that may provide spiders with easy entryways to your home.

If you trim grass and weeds on your property, you will discourage spiders from living nearby. The same goes for removing trash and debris from your yard.

Use a vacuum cleaner to remove spider webs, egg sacs, and spiders inside your home, garage, and attic.

Wear work gloves when you work in areas with poisonous spiders. Shake out linens, shoes, clothes, and towels before use, especially if they haven’t been used for extended periods.

Chemical spider control is an extremely effective for getting rid of poisonous spiders. You should hire a professional to apply a residual pesticide inside and around your home.

Unfortunately, over-the-counter pesticides are not strong enough to effectively control poisonous spiders. When you talk to a pest control professional, ask about contact pesticides.
