WHAT TO LOOK FOR
Wolf spiders survive by camouflage, so their color will resemble their preferred environment. They are a variety of browns, grays, and blacks. They are spherical in shape between ½ to 2 inches long with hairy bodies. Their eyes are arranged with four small eyes on the bottom, two large eyes in the middle, and two medium-sized eyes on the top. Female wolf spider will carry their egg sacks and young spiders with them.
Black widows like protected areas to spin their irregular webs. Locations such as stone or woodpiles, barns, sheds, shrubs, garages, basements, and crawlspaces. They usually do not enter homes but will do so if an area is cluttered and/or undisturbed. Look for the distinctive black body with red or yellow hourglass shape on the females.
Reducing the insects a spider preys on will help reduce populations. Reduce clutter and periodically clean basements and outbuildings. Store firewood away from buildings. Wear gloves and long sleeves and be careful when moving stored items around.
Occasionally property insurance will cover removing the bats, cleaning up the feces and any dead bats, as well as replacing any damaged insulation material. Insurance will not cover sealing up entry points.
