Rodent Control & Permanent Exclusion

Stop Mice and Rats Before They Destroy Your Home

Mice and rats are more than a nuisance — they are incredibly destructive. They squeeze through gaps as small as a dime, chew through structural wood, tear up insulation for nesting material, and gnaw on electrical wiring, creating a serious fire hazard.

Most pest companies trap a few rodents and leave. The Cozy Penguin handles the entire problem — removal, permanent exclusion, and full insulation cleanup — so they don't come back.

Our Process

A complete 4-step rodent exclusion process

From the first knock on the door to the last sealed gap, here is exactly what we do — and why.

Rodent Removal

What happens: We safely remove the active mice or rats currently nesting in your home using targeted, humane trapping.

The goal: Eliminate the immediate threat of active pests before any repairs begin.

Entry Point Identification

What happens: A thorough structural inspection to locate every single gap, crack, or hole where pests are getting in.

The goal: Precision tracking — remembering that mice can squeeze into openings as small as a dime.

Permanent Exclusion

What happens: We seal the home with durable, rodent-proof materials at every identified entry point.

The goal: Block future generations of rodents from ever getting back inside.

Cleanup & Sanitation

What happens: We remove ruined, soiled, or contaminated insulation that rodents used for nesting and sanitize the area.

The goal: Restore your home to a safe, sanitary, hazard-free condition — especially critical where wiring has been gnawed.

"Absolutely an amazing company with astounding customer service and a super helpful and knowledgeable team! The work they did insulating the old side of our basement is amazing. It looks so good and it's already more comfy on that side of the house! We appreciate the care they put into it ensuring they did the job right. We are so happy with the results! I highly recommend this company. Cozy Penguin, you rock! Money well spent before winter."

"Very happy with Koala. From getting the quote, scheduling the job and having the work done. My wife was home the day the job was done. Very friendly group of workers. My current attic blow-in insulation was settled and sparse. I had plywood down for storage. I removed all except 1½ sheets in front of attic door. We had Koala blow in more over existing insulation. Very fair price."

"After the disaster of our ceiling falling down, Salim and his team at The Cozy Penguin got us back in the game with quick and reliable service. If you're in an older home and on the fence about upgrading your insulation, please don't hesitate to reach out to Salim — he will work with you to get your house insulated properly. We just had it installed the other day and you can already tell the difference in the heating system and how the house holds the temperature, rather than feeling drafts and the furnace running constantly. We also had them install a solar attic fan to further reduce energy costs. If you're in the market for insulation, look no further than Salim and The Cozy Penguin!"

FAQ

Rodent control questions, answered

The questions homeowners ask us most often. Don't see yours? Ask us directly.

How small a gap can a mouse fit through?

An adult house mouse can squeeze through a gap roughly the size of a dime — about 1/4 inch. Rats can fit through openings around 1/2 inch. That's why locating and sealing every entry point is essential to permanent rodent control.

Why isn't trapping alone enough to solve a rodent problem?

Trapping removes the rodents currently inside your home, but it does nothing about the openings that let them in. As long as those entry points stay open, new rodents will move in from outside. Permanent exclusion — physically sealing the structure — is what stops the cycle.

Do rodents in the attic really require insulation replacement?

Yes. Rodents tear up insulation for nesting material and contaminate it with urine and droppings, which can carry pathogens such as hantavirus and salmonella. Contaminated insulation also loses much of its R-value, so removal and replacement restores both sanitation and energy efficiency.

Can mice and rats really cause house fires?

Yes. Rodents instinctively gnaw to keep their incisors worn down, and electrical wiring is a common target. Damaged wire insulation is a well-documented cause of residential fires, which is why electrical inspection is part of a complete rodent remediation.

How long does the full rodent exclusion process take?

Most homes are inspected and sealed within one to three visits over one to two weeks, depending on the size of the home, the severity of the infestation, and the extent of insulation damage. You'll get a clear, written timeline after the free inspection.

Do you offer a warranty on the exclusion work?

Yes. Every sealed entry point is backed by our written exclusion warranty. If a rodent finds its way back in through somewhere we sealed, we come back and fix it at no cost.

Is the process safe for pets and children?

Yes. We use targeted mechanical trapping rather than scattering rodenticides throughout the home, and any materials used in exclusion are non-toxic. We'll walk you through every product and method before we start.
