Common Pests in the Southeast
The Southeast experiences some of the highest pest pressure in the continental United States due to its warm, humid climate and long growing seasons. Year-round mild temperatures allow many pest species to remain active even during winter months, with explosive population growth in spring and summer.
Hot, humid summers with mild winters; average annual rainfall of 50-65 inches supports dense vegetation and standing water that fuels pest breeding cycles.
Seasonal Pest Activity
spring
Termite swarm season begins in earnest, with subterranean and drywood termites producing winged alates. Fire ant mounds multiply rapidly in yards and fields. Mosquito populations surge as standing water accumulates from spring rains. Carpenter ants become active in damp wood around foundations.
summer
Peak season for nearly all pest categories. German and American cockroaches invade homes seeking moisture and food. Mosquitoes reach their highest populations, particularly Aedes species carrying disease. Yellowjackets and paper wasps aggressively defend nests near structures. Fleas and ticks thrive in shaded yards and wooded edges.
fall
Stink bugs, lady beetles, and other occasional invaders seek winter shelter inside homes. Rodents begin moving indoors as temperatures cool. Brown recluse spiders are commonly found in storage areas and garages. Fire ants remain active and territorial through late fall.
winter
Mild winters keep cockroaches, rodents, and spiders active indoors year-round. Subterranean termites continue feeding below the frost line. Overwintering pests like cluster flies and lady beetles emerge on warm days. Indoor ant activity persists in heated structures.
