They feed on diverse diets, including pollen, fungi, nematodes, insects and mites, and may be dispersed by various insects, inluding bees. Blattisociidae often have a short (1-2 weeks) life cycle.

Economic importance: Some Blattisociidae, such as Blattisocius tarsalis, prey on and partake in the control of some pests, like Ephestia cautella and of nematodes.
