How are Spiders a Pest?

Harmful Spiders – Brown Recluse & Black Widows

The only two venomous spiders that we find in Metro East Illinois are Brown Recluse spiders and Black Widows.  Both prefer to stay outdoors, but may come inside when the weather outside is bad.

Thankfully, both of these spiders prefer to stay outside. When they do come inside, they like dark secluded, dry spaces where they can hunt other insects.

Brown Recluse

The Brown Recluse spider is a hunter, but they don’t hunt anything bigger than other small insects.  While they do build webs, they use their webs as homes, to lay eggs and store food.  They are rarely found inside homes, but if you do find them they’ll be in a dry, out of the way place like your basement, closet, attic, or perhaps a box or books that don’t move very often.  They like cracks and crevices that are good hunting grounds and keep them secluded.  Outdoors, you’ll find them in wood piles, or brush.

Black Widow

Black Widow spiders are gatherers, they build large sprawling webs close to the ground to capture other insects for food.  They can come indoors when the weather gets cold, but it is quite rare.  Black Widows prefer to stay outside under a deck, inside sheds, hollow stumps, wood piles, places that are cool, dark and dry.

Nuisance Spiders

All other spiders found in our area are nuisances, but they’re not dangerous.  Orb Weavers and Wolf Spiders look frightening, but they’re generally harmless.  Some spiders can bite, but they’re not venomous.  They may cause a pinch or an itching sensation if you get bit, but it will pass quickly.

How to Deal With Spiders in Your Home

To Keep Spiders Out, Keep Insects Out
