Find Out When You'll See Certain Pests More Often

Down here in the Southeast, we don't really get a true "pest break." From the coastal lowcountry of South Carolina and the rolling hills of Georgia to the varied landscapes of North Carolina, our warm, humid climate means pests are active 365 days a year. They don't disappear; they just change tactics.

The secret to a pest-free home is beating them to the punch. To help you protect your property, we've broken down exactly how local bugs and rodents adapt to our changing Southern seasons.

Spring: The Great Awakening

When that classic Southern spring humidity returns and the rain starts falling, the local pest population wakes up hungry and ready to expand.

• Subterranean Termites: Spring is prime time for termite "swarms." Winged swarmers leave their underground colonies looking for damp wood to start new ones—frequently targeting residential crawlspaces and foundations.
• Foraging Ants: As colonies expand, scout ants venture indoors in massive numbers, searching for sweet or greasy food sources in kitchens and pantries.
• Mosquitoes: Once temperatures consistently cross the 50°F mark, dormant eggs in standing water—even in a puddle as small as a bottle cap—begin to hatch.

Summer: Population Explosion

Our brutal Southern heat and high humidity act like rocket fuel for insect populations. Summer is when pest pressure reaches its absolute peak.

• Mosquitoes & No-See-Ums: Backyard gatherings quickly become battles against aggressive mosquitoes and biting gnats that thrive near our coastal marshes and humid inland areas.
• Stinging Insects: Wasps, hornets, and yellow jackets reach peak colony sizes, making them highly defensive and territorial around porches, eaves, and decks.

Fall: The Indoor Invasion

As the crisp autumn air moves in, local pests realize it's time to find a winter bunker. Your cozy, climate-controlled home becomes their primary target.

• Rodents (Mice and Rats): Roof rats and house mice excel at finding tiny structural gaps—some no larger than a dime—to invade attics, crawlspaces, and garages.
• Spiders: While they help control other bugs all summer, fall is mating season for many local spider species, bringing them out of hiding and into plain sight.
• Kudzu Bugs & Stink Bugs: These invasive pests love to gather on the sunny, warm sides of Southern homes before squeezing through window screens and siding cracks to overwinter.

Winter: Seeking Warmth and Moisture

Outdoor bug activity slows down when the frost hits, but the pests that successfully breached your home's defenses are now settled in for the winter.

• Mice & Rats: Once inside, rodents will nest in your home's insulation, chew through wiring, and forage through your pantry at night.
• Cockroaches: German and American cockroaches look for the dark, damp microclimates inside your house—frequently congregating behind kitchen appliances, under bathroom sinks, and in water heater closets.

The Palmetto Promise: Every region in the Carolinas and Georgia faces its own microclimates and specific pest challenges. A generic, one-size-fits-all spray won't cut it.
