The most common spiders found in homes and businesses are the yellow sac spider, cellar spider and house spider. Spider sizes range from 1/8” to 11/32” long. These are not aggressive and usually only bite when provoked. In this region, the yellow sac spider can be a concern due to its capability of piercing the skin and delivering a very painful bite. Each house egg sac can contain up to 400 eggs, with a single female producing an average of 10 egg sacs per year.

Can Spiders Harm Me?

Not all spiders are capable of piercing the human skin. The brown recluse has been known to cause necrosis and the black widow can deliver neurotoxin that can cause severe, painful reactions. Fortunately, neither one of these are commonly found in Wisconsin.

Some spiders in this region can bite but most of their venom does not causes necrosis. Most bites are often misdiagnosed and rarely occur. They are considered to be an unsightly nuisance pest and generally not tolerated by people.

Do Spiders Cause Damage?

Spiders do not cause any structural damage. However, they can create an unpleasant environment with their unsightly webbing.

What Can I Do?

Spiders are common in the environment and large numbers are usually associated with high moisture and water sources. Sealing gaps in the foundation, fixing door seals or pipe entries will help, but these critters seem to find their way in. Reducing lush landscaping and making sure that foliage is trimmed away from your home or business will help reduce harborage for it.

Reducing lighting on a structure or building is also a good way to reduce the attractiveness to spiders. As a home owner, you can vacuum it up and remove the webs as they appear. Most of the time physical removal is time consuming and hard to keep up with especially around lakes and water sources. Contact us today for professional assistance and peace of mind.

Frequently Asked Questions

What types of spiders do you treat?

We treat common species found in homes and businesses, including yellow sac, cellar, and house varieties. Each type is addressed with a targeted approach based on its behavior and nesting habits.

Most are not aggressive and will only bite if disturbed. However, some species, like the yellow sac variety, can deliver painful bites, making it important to manage infestations properly.

Increased activity indoors often means there is a food source available, such as other insects. They may also enter structures seeking shelter, especially during seasonal changes.

Populations can grow quickly due to their reproduction rate. A single egg sac can contain hundreds of eggs, and one female can produce multiple sacs in a year, leading to rapid increases if not controlled.

Our team identifies entry points, removes webs and nesting areas, and applies targeted treatments to reduce activity. We also provide recommendations to help prevent future infestations and keep your property protected.
