It's common to be afraid of all spiders, but the harmful species - such as the Black Widow - are the ones you should really be afraid of. According to Do-It-Yourself Pest Control, Black Widow Spiders are considered poisonous, spiteful spiders in North America. Fortunately, Black Widows are not usually lethal, because they can only inject a small amount of venom into humans, but they can still be harmful.
Minimize the hiding spots - Pestkill suggested getting rid of as many Black Widow hiding spots as you can. This includes boxes piled up throughout your home, clutter in the basement, unnecessary outdoor items or garage contents and debris left in the yard.
Inspect constantly - Make sure you're always checking for webs, egg sacs and spiders throughout your home. The more often you check and clean up the space, the less chance you'll find Black Widows taking residency in your house.
Keep vacuuming - By now you know that vacuuming up the Black Widow and its contents is an effective way to get rid of them, but it's an excellent way to prevent them from coming back, too. Always make it a point to dust and vacuum under furniture, in corners of the room and windows throughout your home. This will help remove the clutter of dirt and debris, giving the Black Widow no place to hide.
Store firewood safely - The National Pest Management Association suggested storing firewood at least twenty feet from your home and about five inches off of the ground. Piles of firewood are a common place for Black Widows to hide and reside in. The closer the piles are to your home, the greater the chance of the spiders' finding their way into your house is. Therefore, keeping your firewood as far away from your home as possible is the smartest choice.
