House Spiders

DOMESTIC SPIDER PREVENTION

To prevent common house spiders from entering the home, seal cracks and use screens on windows and doors. Use a vacuum to remove adults, egg sacs and webs. If a broom is used, adult house spiders can usually escape.

The common house spider is usually the spider most often encountered indoors. It is a nuisance pest, probably more because of its webs than the spider itself. The house spider is found worldwide and is common throughout the United States and Canada.

Habits

The boxelder bug population lives and thrives on maple and seed-bearing boxelder trees during the warmer months where they lay their eggs and feed on leaves, flowers and seeds. Occasionally, they will feed on the fruits of plum and apple trees.

Habitat

The house spider randomly selects its web locations and creates a tangled web. If a web does not yield prey it is abandoned, another site is selected, and a new web is built.

Threats

Common house spiders are nuisance pests, but they pose no threats to humans.
