Rodent Exclusion and Entry Point Sealing in Middleburg, FL

Exclusion work starts with a full exterior walk of the house, checking the foundation, roofline, vents, utility penetrations, and the gap under garage doors. A mouse needs a gap about a quarter inch wide and a rat needs about a half inch, so the inspection looks closely at spots that are easy to overlook from a distance.

Older homes near the center of Middleburg often have gaps around original plumbing chases and low block foundations that were never sealed against rodents in the first place, while newer construction more often has gaps around garage doors and dryer vents.

Entry points are closed with galvanized steel mesh, sheet metal, and mortar depending on the material and location, not spray foam alone, since foam is chewed through in a matter of days. Vents get rodent-proof covers that still allow airflow, and door sweeps are replaced where gaps have opened up under garage and exterior doors.

• Steel mesh packed into gaps around pipes and utility lines.
• Escutcheon plates and vent covers rated to resist gnawing.
• Door sweeps and thresholds replaced where wear has created a gap.

If mice or rats are already active, exclusion work is scheduled after trapping has reduced the population, so animals are not sealed inside the house. On smaller jobs with light activity, sealing and trapping can sometimes happen in the same visit.

Sealing closes existing entry points but does not treat an active infestation on its own. If droppings or noise continue after sealing work, call back so we can check whether a new gap has opened or whether animals were sealed in rather than out.
