Bed bugs are elusive and usually nocturnal, which can make them hard to spot. They often lodge unnoticed in dark crevices, and eggs can be nestled in fabric seams. Aside from bite symptoms, signs include fecal spots, blood smears on sheets, and molts.

Bed bugs can be found singly, but often congregate once established. They usually remain close to hosts, commonly in or near beds or couches. Harborage areas can vary greatly, however, including luggage, vehicles, furniture and bedside clutter. Bed bugs may also nest near animals that have nested within a dwelling, such as bats, birds, or rodents. The eggs of bed bugs are found in similar places where the bed bugs themselves are found, and are attached to surfaces by a sticky substance. Attractant devices for detection use heat and/or carbon dioxide.

Bed bug control requires significant work on the part of both the resident and your pest control technician.
