Mice and rats do not need an obvious opening to get indoors. In Florida, rooflines, utility penetrations, garage corners, vents, and landscaping can all create routes into homes, while warm conditions allow rodent activity to remain a year-round concern. The most useful residential rodent control methods focus first on exclusion, then on removing the food, water, and shelter that make a property worth revisiting.
Start With the Smallest Gaps
Walk the exterior slowly and check where plumbing, electrical, cable, and air-conditioning lines enter the structure. Inspect door sweeps, garage-door corners, crawl-space or attic vents, soffits, and the joint between the foundation and exterior wall. The CDC notes that mice can fit through an opening about 1/4 inch wide, so gaps that look insignificant may still need attention.
Use Materials Rodents Cannot Easily Push Through
Caulk alone is not the answer for every hole. CDC guidance recommends steel wool secured with caulk for small openings and stronger materials such as hardware cloth, metal sheeting, cement, or lath screen for larger gaps. Match the repair to the location and replace damaged vent screens or worn weather stripping instead of simply covering the surface.
Check Rooflines and Landscaping Together
Roof rats are capable climbers, which makes upper-level access just as important as foundation gaps. UF/IFAS recommends pruning limbs away from the house because rats and squirrels can use touching or overhanging branches as routes toward roofs. After heavy rain or storm-related repairs, recheck soffits, fascia, roof vents, and screens for new damage.
Remove the Reasons Rodents Stay Nearby
Exclusion works better when the yard and kitchen are less rewarding. Keep garbage tightly covered, clean grills and outdoor eating areas, store pet food and pantry goods in sturdy sealed containers, and pick up spilled bird seed. Move clutter and dense vegetation away from exterior walls. Fix leaking faucets and avoid leaving pet food or water out overnight. These steps do not replace treatment when rodents are already established, but they reduce competing food and shelter.
Do Not Seal an Active Infestation Inside
Fresh droppings, scratching in walls or ceilings, gnaw marks, nesting material, or repeated nighttime sightings may indicate active rodents, although individual signs can have other explanations. Before closing every opening, determine whether animals are already inside.
