Why Nonvenomous House Spiders Are More Than Just A Nuisance

Here in Knoxville, we get to see a wide range of wildlife, some of which we enjoy more than others. When it comes to spiders, we all know to stay away from the two poisonous types that live here, the brown recluse and the black widow, but did you know you should also be wary of having nuisance spiders take up residence in your home?

Below are three common nuisance spiders that live in the Knoxville area, why you don’t want them in your home, and what to do if you discover they have already invaded:

Orb Weaver Spiders

As their name suggests, orb weaver spiders weave intricate, wheel-shaped webs that they anchor between tree branches or other objects in order to catch their prey.

Orb weavers range from ¼ of an inch to 1 inch in length. These spiders have brown or black bodies with brightly colored markings on them that can be red, yellow, or orange. Their legs are spiny and hairy.

Orb weaver spiders are also commonly referred to as garden spiders as they are typically found in garden areas. These spiders can also be found in the corners of doorways, porches, and decks. Because the insects they feed on are drawn to light, they are also often found near porch lights.

Although they will bite if threatened, orb weaver spiders are not dangerous and their bites typically do not cause any health problems for humans.

Wolf Spiders

Wolf spiders range in size from ¼ inch to about 1 ½ inches. The females are typically larger than the males. These spiders have dark brown bodies with light brown or yellow colored stripes and long spiny legs. Wolf spiders can also be identified by their unique eye arrangement: four small eyes on the bottom row, two large eyes in the middle, and two medium-sized eyes on top.

Wolf spiders do not build webs. Instead, they hunt and capture their prey.

Although their name indicates otherwise, wolf spiders are not aggressive and would rather hide from humans than bite them. In addition, the bites of these spiders pose no serious threats to humans.

Cellar Spiders

Cellar spiders have small bodies that range in size from ¼ to ⅜ of an inch long and are typically pale yellow, light brown, or gray in color. Because of their long, skinny legs, cellar spiders often get confused with daddy long legs.

Cellar spiders build large, irregular-shaped webs that they continually add to. These spiders are social spiders and prefer to live in groups.

Cellar spiders cannot bite because their mouths are too small and therefore pose no danger to humans.

Why You Don’t Want Nuisance Spiders in Your House

Although they pose very few health risks in and of themselves, the presence of nuisance spiders in your home is not something to ignore. Though having nuisance spiders living inside your home is unpleasant enough, the presence could indicate other problems as well.

Spiders prefer to live in areas with high humidity levels. High humidity in your home or basement is not just uncomfortable, but could actually cause or indicate damage. Reduce humidity in your home by installing dehumidifiers, running fans, and making sure you have no leaking pipes or drainage issues.

Spiders also like to live near abundant food sources. If you begin to find large populations of nuisance spiders in your home, it could indicate that you have another pest problem as well!

What to Do About Them

Ridding your home of nuisance spiders from your home can be tricky business. Besides keeping humidity low and food sources to a minimum, you should also check outside your home for cracks or spaces that would provide them with easy entry to your home and seal any that you find.
