Woodlouse spiders are usually found under logs, rocks, bricks, plant pots and in leaf litter in warm places, often close to woodlice.

They spend the day in a silken retreat made to enclose crevices in, generally, partially decayed wood, but sometimes construct tent-like structures in indents of various large rocks.

[3] The woodlouse spider's powerful jaws are made to impale the thick armor of woodlice and are strong enough to give humans a painful bite.

Although the woodlouse spider is a dangerous predator to woodlice, it is not known to be a health hazard to humans or smaller animals.

[6] Laboratory experiments have shown D. crocata will take other invertebrates, and shows no particular preference for woodlice; these are simply the most common prey in its habitat.
