Rodent control in Trussville, AL — one call to a licensed operator.

Trussville is growing faster than almost any city its size in Alabama, and that growth is exactly what shapes its rodent problem. The historic Cahaba Project, built in the 1930s under the federal Subsistence Homestead program, is one of Alabama’s few surviving New Deal planned communities — small cottages set on crawlspace foundations nearly a century old now, with sill plates, vent gaps and utility penetrations that have had decades to settle and loosen. That older stock gives rodents an easy, familiar way indoors that has nothing to do with the city’s recent growth.

The newer subdivisions pushing out along Happy Hollow Road and Roper Road tell a different story. This is farmland and open field converted to residential lots in real time, and every acre of dirt work displaces the field mice, voles and other rodents that were already living there — they do not vanish when the bulldozers arrive, they move to the nearest cover, which is often the half-finished house next door or the landscaping of a just-completed one. New construction also comes with its own entry points before anyone has thought to check for them: garage corner gaps that never got fully sealed, brick weep holes left wide open, and utility penetrations around a new HVAC line set that a builder’s crew moved past quickly.

The Pinnacle at Trussville and the surrounding retail growth along I-59 add a commercial-corridor pressure of their own. Restaurant and retail dumpster areas across a shopping center that size generate a steady, reliable food source, and an unsealed enclosure or an overflowing dumpster can sustain a ground-level rodent population that spreads into the residential subdivisions built up around and behind the retail corridor in recent years.

The Cahaba River, which runs through the heart of Trussville, and its feeder creeks give rodents a natural corridor as well — brush, culverts and streamside cover that let them move between wooded stretches and the residential lots that increasingly back right up to the river as development pushes closer to it.

Which species shows up tends to split along the same lines as the housing stock. House mice, small and adaptable, are common in the newer subdivisions where fresh construction gaps offer easy entry and food sources are still being established in yards and gardens. Roof rats, which prefer a mature tree canopy to climb, are more likely in the older, more established parts of town like the Cahaba Project and the streets around it, where decades-old trees actually touch rooflines the way a brand-new subdivision’s saplings do not yet.

Alabama’s real cold snaps typically arrive by November, and that is when both stories converge — field-displaced mice in the new subdivisions and canopy-based roof rats in the older neighborhoods both push indoors at roughly the same time, which is why November tends to be Trussville’s busiest month for rodent calls regardless of which part of the city they come from.

Exclusion is the fix in either case, but where to look differs by house age: a new-build garage corner or weep hole in a Roper Road subdivision, versus a settled sill plate or vent gap in a Cahaba Project cottage. An operator who works both ends of Trussville checks the entry points that actually match the house in front of them.

• “Is this a house mouse or a roof rat?” New subdivisions tend to see house mice from displaced field populations; older canopy neighborhoods like the Cahaba Project tend to see roof rats. The species changes where the operator looks for entry points.
• “What’s your ADAI license number?” Every legitimate Alabama operator carries one, and the Pesticide Management Section in Montgomery can confirm it. A pro expects the question.
• “Will you check the garage corners and weep holes if I’m in a new build?” Fresh construction often has unsealed gaps a builder’s crew moved past quickly. Ask the operator to specifically inspect garage corners, brick weep holes and utility penetrations rather than assuming a new house has no entry points.
• “Will you check the crawlspace sill plate if I’m in the Cahaba Project?” Nearly a century of settling can loosen sill plates and vent covers on this historic stock. Ask whether the crawlspace access point was inspected, not just the exterior.
• “Snap traps or bait stations, and why here?” A garage or crawlspace with limited foot traffic often favors snap traps on a confirmed travel path; a yard with kids or pets favors secured, tamper-resistant bait stations. Ask which applies to your property.

None of these questions slow down an operator who works both Trussville’s historic core and its newest subdivisions every week — the answers tell you whether the plan matches the age of your house.
