When Are Roaches Most Active?
Cockroaches are often found in dark, warm and moist areas inside houses, hotels and restaurants. Some species also thrive in sewers or outdoors. Most cockroaches hide in dark, secluded areas by day. They can be found behind furniture and appliances, as well as under refrigerators and stoves and in cupboards or cabinets. They are capable of flattening themselves in order to fit into crevices between floorboards and walls. Roaches are most active at night, during which time they forage for food and mate.
Outdoor cockroaches in the northern United States enter a period of hibernation in winter, experiencing a suspended state of development in autumn. When spring arrives, they resume their activity.
Cockroaches are social insects that usually live in groups. Cockroaches emit pheromones that leave chemical odors in their feces and on their bodies. These pheromones serve as means of communication for the insects. The odor of the pheromone causes the roaches to cluster together in a harborage area. If you suspect cockroach activity, contact a pest control professional to discuss treatment options.
