Occasional Invaders

Occasional invaders are as diverse a pest group as you can get. They are insects or other arthropods that enter structures sporadically. They can occur in small or large numbers throughout the year and are most often considered a nuisance. They usually live and reproduce outdoors. Because this group has such a diversity of species there is no general life cycle or physical description for this overall group. A few of the common species are below.
