Occasional invaders come in many shapes and sizes. They are the pests that come in through a crack, an open door, a hole in a screen, a potted plant, or a piece of firewood. They do not often infest a home (that is, feed and breed), so are more a nuisance than anything. Common invaders are ground beetles, sow bugs, millipedes, crickets, wood cockroaches, cluster flies, lady beetles, springtails, leaf-footed bugs, hornets, wasps, and earwigs. Not to mention all the tiny night-flying insects that fit through a screen, heading toward your light. occasional invaders are often just nuisance pests because they cannot survive for long periods of time indoors. Take, for example, the brown marmorated stink bug, which has become notorious for its "smelly" reputation.
