Woodlouse Spider Facts & Information

What Orkin Does

Homeowners usually do not need to deal with woodlouse spiders if they don’t have a woodlice infestation, which is also a sign of a potential moisture problem. Since woodlice are the major source of food for woodlouse spiders, the best way to keep these spiders away is to get rid of a woodlice infestation and manage moisture levels. Removing or reducing the amount of mulch, leaf litter, and pine straw next to your home will also help deter these spiders.

Orkin is trained to help manage spiders and similar pests. For more information on spider treatment, call your local Orkin branch.

What Do Woodlouse Spiders Look Like?

Adult female woodlouse spiders are about ½ inch long, while males are slightly smaller. The woodlouse spiders have a dark red or orange body offset by a grayish-white abdomen. They have six eyes tightly clumped together. They also have very long fangs that they use to deter predators and capture prey.

Woodlouse Spider Life Cycle

The woodlouse spider overwinters in its adult form. Mating occurs in early spring with up to 70 eggs being deposited shortly thereafter. Eggs are suspended within the female's silken retreat by a few strands of silk. The immature spiderlings will at first remain with the female, living in her sheltered location until they’re ready to venture out on their own.
