Black widow spiders are easily identifiable due to their distinctive color patterns.

Ways on How to Get Rid of Black Widow Spiders Naturally

Strong Scents

Black widow spiders, both males and females, have shown an aversion to potent fragrances, specifically those of lemon, tea tree oil, eucalyptus, and peppermint. These scents act as natural spider repellents, dissuading black widows from occupying and returning to sprayed locations.

This can be a useful strategy to prevent black widow spider bites. A homemade spray, concocted from these natural ingredients, can be employed and distributed in spider-infested regions of your house.

Diatomaceous Earth

Diatomaceous earth, a sedimentary rock that occurs naturally, can serve as an effective physical means to manage black widow spiders. This substance functions by slicing through the spider’s exoskeleton, leading to dehydration and eventual death of the spider.

This is particularly effective against female black widow spiders, known for their more potent venom. Scatter this remedial material around suspected spider hideouts and places of spider activity.

Setting Spider Traps

An additional all-natural method to keep black widows, particularly male black widows, in check involves the use of spider traps. These traps, fabricated from adhesive cardboard, can be situated in areas where spider presence has been detected.

The spiders, attracted by the scent of the lure, become ensnared on the gluey surface, thus effectively curtailing their proliferation.

This could include closets, basements, garages, attics, and other areas that are often undisturbed. Make sure to mop the floors and dust off spider webs so they don’t have any places to hide.

Seal Cracks and Crevices

These spiders often use small gaps in walls, floors, and around windows and doors to enter homes. By sealing these potential entry points, you can make your home less inviting to black widow spiders and other pests.

What Kills Black Widows Instantly?

Look for pesticides that have an active ingredient of pyrethroid, permethrin, or carbaryl as these are the best insecticides against spiders. Make sure to follow the directions on the label and use protective equipment such as gloves and masks when you’re spraying them.

Another thing you can do is to make a vinegar solution with equal parts white vinegar and water in a spray bottle. This natural mixture is effective against black widow spiders and other pests. Spray it on areas where you suspect the spiders are hiding, paying special attention to cracks, crevices, windowsills, and door frames. The acid from the solution will kill black widows instantly.
