Rodent Control & Exclusion in Bellingham, WA

When the rain sets in, rats and mice head indoors — into crawlspaces, attics, walls, and garages. We find how they’re getting in, remove them, and seal the structure so they stay out.

On every visit, our technician inspects the interior, exterior, attic, and crawlspace to identify rodent access points into the structure — then builds a plan to trap, exclude, and prevent. It’s all backed by our 100% service guarantee, with no long-term contracts.

Rodent Exclusion That Lasts

Rats and mice can squeeze through gaps the size of a dime or a quarter. Our exclusion work closes those gaps with rodent-proof materials so new rodents can’t move in after the current ones are gone — for homes and businesses alike.

Frequently Asked Questions

Why not just set traps myself?

Traps catch the rodents you have, but if the entry points stay open, more move right in. Our service focuses on sealing the structure so the problem is actually solved.

Do you get into the crawlspace and attic?

Yes — that’s where most rodent activity is. We inspect and treat those spaces, and can restore damaged crawlspaces, including removing and replacing rodent-damaged insulation.

Is it safe around kids and pets?

Yes. We use tamper-resistant bait stations and place them responsibly, and we’re glad to talk through any concerns before we start.

Rats or mice on your property? We’ll seal them out.
