Memphis really does have two different rat problems depending on which part of town you're in. In Midtown, Cooper-Young, Central Gardens, and the older streets of Vollintine Evergreen, mature oaks and power lines put roof rats within easy reach of a roofline, and many of these houses still sit on real crawl spaces or, on the higher ground toward East Memphis, an honest basement โ both of which give a ground-dwelling Norway rat somewhere to den undisturbed for months. Out in Cordova, Bartlett, Collierville, and the newer edges of Germantown, slab construction is the norm and tree cover is thinner, so the pressure shifts toward Norway rats and mice working fence lines, AC pads, and foundation gaps rather than roof rats working an attic.
Memphis's climate doesn't give rats much reason to slow down. Summers push into the high 90s with brutal humidity, which sends rats looking for shade, standing water, and the cool relief of a crawl space or an air-conditioned attic. But Memphis also gets real winter cold snaps and the occasional hard freeze or ice event, unlike the Gulf Coast, and that cold is enough to push rats out of yards and into wall voids from late fall through midwinter. The result is a two-season pattern rather than one dominant surge โ a summer moisture push and a genuine cold-weather push indoors, both worth watching for.
The ground under Memphis adds its own wrinkle. Much of the city sits on thick loess โ wind-deposited silt โ layered over river-bottom clay near the Mississippi, and that soil settles and shifts unevenly compared to harder Piedmont or Blackland Prairie ground. Foundations move a little every year, brick veneer separates slightly from sill plates and window trim, and a gap that didn't exist when the house was built opens up gradually near a foundation vent or utility penetration โ exactly the kind of quarter-sized opening a rat needs.
We start every call with an inspection, not a bait drop, checking the exterior, attic, and crawl space or basement for burrows, rub marks, droppings, and gnaw damage to confirm whether we're dealing with roof rats, Norway rats, or โ common in Memphis's older, mixed-construction neighborhoods โ both on the same block. We trap the active population first, then seal every entry point with heavy-gauge hardware cloth, galvanized flashing, and mortar patching, never foam or steel wool alone. You get a written report and a workmanship warranty on the exclusion work. Call (877) 240-9073 for a free inspection.
