Common Rodent Entry Points to Seal

Why exclusion is the only real fix

Traps remove the rodents you have. Exclusion stops the next ones from getting in. Without sealing entry points, a Florida home will get re-infested within a season. Here are the openings local pros check first.

Common entry points on Treasure Coast homes

Roof return and eave gaps

Where the soffit meets the fascia at the corners. Even a 1/2 inch gap is enough for a roof rat. Often hidden behind gutters.

Plumbing and AC line penetrations

Holes cut around copper lines, condensate drains, and pool plumbing often go un-foamed or get chewed open at the foam.

Garage door corners and weather seals

Mice and young rats slip in through the gap at the bottom corner of the garage door, especially on uneven slabs.

Roof vents and turbines

Plastic vents crack in the Florida sun. The mesh on attic gable vents rusts through near the coast.

Soffit returns over porches

Open or torn soffit panels above screened lanais are one of the most common roof-rat highways into the attic.

Sewer and dryer vents

Missing dryer vent flaps and uncapped roof stacks both lead straight into the building envelope.

Materials that actually hold up

• 1/4-inch galvanized hardware cloth, not screen
• Copper mesh packed into voids before sealing
• Sheet metal or backer rod plus exterior-grade sealant
• Self-closing dryer vent covers

Spray foam alone fails. Rodents chew through it. Foam is only acceptable as a finish over hardware cloth or copper mesh.

The order of operations

Inspect first. Then trap. Then seal. Cleanup last. Sealing before trapping leaves rodents trapped inside the walls, which is loud, smelly, and worse than the original problem.
