How to get rid of poison spiders in your home?

Seal the entries

Examine your home thoroughly, including the insides of closets and crawl spaces, and seal up any wall cracks or crevices that could serve as entry points for spiders. No new spiders will be able to enter this way.

Avoid the mess at home

Clear all debris from the outside of your house, such as lawn clippings, branches, limbs, and wood, and clean out any clutter from any dark, cool, and dry areas of your home, such as your basement or attic.

These are popular haunts for spiders. Wear gloves when removing yard waste and cleaning up clutter to protect your hands from unwanted bites.

Set the traps

After you’ve removed all of the clutter and sealed up all of the spider entry points in your home, you might need to add another line of defense. You can catch spiders using glue mousetraps.

Place the sticky traps wherever you suspect spiders are trying to enter your home, and the traps will catch the spiders as they try to crawl inside.
