The adult Masked Hunter is a striking, shiny, black bug about 3/4” long. The immature (nymph) has a sticky “finish” that attracts lint and dust; in short, stuff sticks to Junior, earning it the nickname “dustbug.” MHs are insect-feeders, untiring consumers of bedbugs, a pest that is staging a comeback in big cities everywhere thanks to the ease of world travel. If you have the predator, perhaps you should check for the prey.
