They are not a household pest because they cannot bite or sting and they do not attack the house structure, furniture or occupants. Pseudoscorpions have 8 legs and are closely related to mites, ticks and spiders. Scorpions, however, are always much larger and have a sting on the end of their abdomens. Natural habitats for pseudoscorpions include under leaf litter and mulch, in moss, under stones and beneath tree bark. They have also been reported in bird nests and between siding boards of buildings.
Pseudoscorpions are predaceous and therefore beneficial.
They feed on other arthropods, particularly small insects and mites. Special treatments for control of pseudoscorpions are usually not warranted. Offending invaders need only be picked or swept up and discarded back outdoors. Iowa State University , Ames, Iowa. This information subject to a usage policy .
