Trapping removes the rats that are inside today. Exclusion is what keeps the next ones out, and it is the step most do-it-yourself efforts skip. Rat exclusion means finding and sealing every gap a rat uses to get in, with materials they cannot chew through. In Denver, where rats are pushed around constantly by construction, the river corridors, and cold winters, exclusion is the difference between a fix that holds and a problem that repeats.

Rats only need a gap about the size of a quarter. A local exterminator seals the low entry points Norway rats use, foundation cracks, crawl-space and utility openings, gaps under garage doors, and the high ones roof rats use along the roofline and vents. Call 720-379-2570 to get the entry points on your property sealed.

The Entry Points That Matter in Denver

Exclusion targets the gaps Denver rats actually use:

  • Foundation cracks and gaps in the older brick and stone foundations common across Denver's established neighborhoods.
  • Crawl-space vents and openings, a main Norway-rat route at ground level.
  • Utility penetrations where pipes, gas, and wiring enter, and gaps under garage and entry doors.
  • Roofline, soffit, and vent gaps for roof rats, plus sewer and lateral-line connections that rats travel underground.

How Exclusion Is Done Right

Exclusion is only as good as the materials and the thoroughness. Foam or caulk alone does not stop a rat that can chew, so a local exterminator uses rodent-proof materials, steel mesh, hardware cloth, copper mesh, and metal flashing, at the gaps that need to hold, and reserves sealants for finishing. Every opening matters, because a rat only needs one.

It also has to come after removal, or in step with it. Sealing a house with rats still inside traps them in the walls, so the sequence is inspect, remove, then seal. Done in that order, exclusion turns a recurring Denver rat problem into a closed one.

Why call a local exterminator

Exclusion Is Where Experience Pays Off

Finding and sealing every entry point on an older Denver home takes someone who knows where they hide: the gap behind the stone foundation, the open crawl-space vent, the spot where the gas line enters, the separated soffit. A local exterminator brings that eye and the right materials, so the seal holds against the constant rat pressure here.

You get a clear scope of what needs sealing and an upfront estimate before any work. No guesswork, and no leaving half the gaps open.

FAQ

Rat Exclusion Questions

What is rat exclusion?

It is the work of sealing every gap rats use to get into a building, from the foundation and crawl space to utility penetrations and the roofline, with materials they cannot chew through. It is what makes removal last.

How small a gap can a rat use?

About the size of a quarter, and they can enlarge smaller openings by gnawing. That is why a thorough exclusion job seals even gaps that look too small to matter.

What materials actually keep rats out?

Rodent-proof materials like steel mesh, hardware cloth, copper mesh, and metal flashing at the real gaps, with sealants for finishing. Foam or caulk alone does not stop a rat, which is why DIY seals often fail.

Should sealing happen before or after removal?

After, or in step with removal. Sealing with rats still inside would trap them in the walls. The order is inspect, remove, then seal, which is how a local exterminator does it.
