Pest control in Atlanta, GA, from the crawl space to the tree line

What pests are most common in Atlanta, GA?

The pests Atlanta homeowners call about most are subterranean termites, cockroaches (American, smokybrown and German), ants, mosquitoes, rats, mice and squirrels. Spiders, wasps, fleas and ticks follow. The mild climate means most of them stay active well beyond the warm months, so a problem rarely resolves by itself when the weather turns.

Many of these pests give early warning. Catching a trail of ants, a few droppings or a handful of shed wings early usually means a smaller job and a smaller bill. The signs below are the ones callers describe most often.

Not every sighting means an infestation. A single large roach on a hot, wet night can be a visitor from the yard, while a second and third in the same week suggests a nest or a path indoors. A technician can tell the difference and will say so.

• Winged insects at a window or shed wings on a sill in spring: possible termite swarmers
• Large brown or dark roaches in kitchens, baths or basements after heat or rain: American or smokybrown cockroaches
• Small roaches in cabinets, behind appliances or in apartment kitchens: German cockroaches
• Scratching or running in the ceiling at night, especially in fall: rats or squirrels in the attic
• Fine trails of small ants along counters after a storm: odorous house or Argentine ants
• Raised mounds in a sunny lawn that erupt when disturbed: fire ants
• Daytime bites on the patio from small striped mosquitoes: Asian tiger mosquitoes breeding in nearby containers

How does Atlanta's long, wet season change pest control?

Atlanta has hot, humid summers, mild winters and rain spread through the year, so the pest season runs for much of the year rather than stopping at the first frost. Indoor roaches and rodents never fully stop, mosquitoes can linger well into autumn, and termite and ant activity can start early in spring.

Hard freezes do happen on some winter nights, but they are usually brief, and the occasional ice storm does not reset the calendar the way a long northern winter does. Remnant tropical systems can also bring heavy rain in late summer and autumn, which pushes roaches, ants and rodents toward drier ground, which often means a house. A plan that goes quiet for months at a time can leave gaps in the calendar below.

The table is a rough guide only. Timing shifts from year to year with temperature and rain, and our month-by-month Atlanta pest calendar goes into more detail.

Why does the crawl space matter in older Atlanta houses?

Many in-town Atlanta houses from the 1880s to the 1930s sit on brick or block piers over a vented crawl space instead of a slab. That space is dark, often damp and out of sight, which makes it a common place for termites, rodents and large cockroaches to settle and for moisture problems to start.

Neighborhoods such as Grant Park, West End, Inman Park, Kirkwood, Virginia-Highland and Adair Park are full of heart-pine and wood-frame houses of this kind. Termites favor wood that touches or sits close to damp soil, and a porch post, a sill or a pier cap can be exactly that. Rodents can enter through vents and gaps, and American cockroaches shelter in damp, dark voids before wandering up into the house.

That is why a thorough termite inspection in these houses usually means someone going under the floor, not just looking at the trim. Our crawl space pest and moisture service covers what a technician looks for there, and our guide on what lives in an Atlanta crawl space explains the vented-versus-sealed question in plain terms.

How do tree canopy, creeks and house type shape pest problems here?

About 45 percent of Atlanta is under tree canopy, according to Trees Atlanta's 2023 report, which means limbs on roofs, deep shade and leaf litter across many lots. Add creek corridors, rail lines, restaurant strips and a mix of crawl-space and slab houses, and each block can have a different pest profile.

Canopy is the quiet driver. Oak and pine limbs that touch a roof are a bridge for squirrels and roof rats, leaf-choked gutters hold water for mosquitoes, and heavy shade keeps wood damp for carpenter ants. On the other side of town, creek and rail corridors give Norway rats and mice a path to the back doors of neighboring homes and restaurants.

House type matters just as much. A 1920s bungalow with a crawl space and a 2020s slab townhome can stand on the same BeltLine-side block, and they have different weak points: sills and vents on one, slab edges, plumbing penetrations and mulch piled against the siding on the other.

• Older in-town streets (Grant Park, Kirkwood, Virginia-Highland): crawl spaces, wood porches, carpenter ants and termites
• Mid-century ranch neighborhoods (Cascade Heights, Candler-McAfee, Forest Park): slab edges, overhanging limbs, squirrels and fire ants in sunny lawns
• Restaurant and apartment corridors (Buford Highway, Clarkston, Doraville): German roaches, bed bugs, rodents
• Creek and park edges (Brookhaven, Sandy Springs, Cascade Springs Nature Preserve area): mosquitoes, squirrels, ticks
• Airport corridor (Hapeville, College Park, East Point): hotels, food service, rail and warehouse land that keep roach and rodent calls steady

What should you check before hiring a pest control company in Georgia?

In Georgia, structural pest control is regulated by the state. Before you agree to any treatment, ask the company for its license details, ask what pest it thinks you have and why, and ask for the total price, including any follow-up visits. A clear answer to each question is a good sign.

Also ask what will be applied, where it will go and what precautions apply to children and pets. A good answer is specific: the pest, the area and how long to stay away from it. If a quote cannot be explained in plain language, that is a reason to pause.
