The most effective long-term defense against rats isn't a trap or a bait station — it's exclusion, sealing your home so rats simply can't get in. Here's how it's done.
Find every entry point
Rats can squeeze through a gap the size of a quarter, so rat-proofing starts with a careful inspection of the whole structure: roofline and fascia gaps, soffit and vent openings, spaces around pipes and wiring, garage door edges, and any hole leading into a wall void or attic.
It's easy to miss the small ones, which is why a professional eye matters — a single overlooked gap is all a rat needs.
Seal with the right materials
Effective exclusion uses durable, rodent-proof materials — heavy-gauge hardware cloth, sealed vent covers, and reinforced closures — not foam or steel wool that rats chew through. Vents are screened, gaps are closed, and the structure is made genuinely rat-tight.
Trimming tree branches back from the roof removes the aerial highway roof rats love.
Exclusion is the lasting fix
Trapping clears the current rats; exclusion prevents the next ones. Done thoroughly, it ends the cycle of repeat infestations. That's why exclusion is the highest-value part of any rodent job.
