Agricultural-Edge Rodent Pressure
Columbia is surrounded by some of Tennessee's most productive agricultural land — horse farms along Pulaski Pike, cattle operations to the south, and the Duck River bottomland running through the county. These landscapes support enormous rodent populations, and the animals don't respect the line between farm and subdivision.
- House Mice — Enter through gaps a quarter-inch wide. Every Columbia home is vulnerable, but properties near farmland face heaviest fall invasion when field mice seek winter shelter.
- Deer Mice — More common on rural-edge properties. They nest in outbuildings and attics and carry hantavirus.
- Norway Rats — Found near the Duck River corridor, commercial areas, and older downtown infrastructure.
Trapping and Exclusion
Snap traps in active runways, entry point sealing with rodent-proof materials, and habitat modification create lasting results. For Columbia's many homes with crawl spaces, we focus on foundation vent screens, plumbing penetrations, and the gap between sill plate and foundation — the most common rodent entry point in Middle Tennessee construction.
