Rodent Control & Attic Restoration That Keeps Your Home Sealed Tight

The Cozy Penguin protects Harrisburg-area homes from mice, bats, and unwanted wildlife — handling complete exclusion and insulation replacement under one roof.

The Cozy Penguin Difference

Pests Out. Comfort In.

The Cozy Penguin earned its name keeping Harrisburg homes warm, efficient, and comfortable. Doing that work taught us something most pest companies overlook: rodents and bats get inside through the very same gaps, cracks, and entry points that let your conditioned air escape.

That whole-home perspective is exactly what makes our pest control different. We don't just trap the mice and leave. We find how and why they're getting in, physically seal the entry points, and completely replace the contaminated insulation. It's the same thorough approach you already trust us for, now protecting your family from unwanted guests.

What We Do

Complete Wildlife & Rodent Control

We specialize in humane, long-term exclusion over quick chemical fixes—addressing the root cause of how pests are entering your home.

Rodent & Wildlife Exclusion

We implement specialized one-way doors and exclusion tactics to safely remove mice, rats, and bats from your property without the need for harmful chemical sprays.

Entry-Point Inspection & Sealing

As insulation specialists, finding hidden gaps is what we do best. We pinpoint the cracks and openings pests use and install permanent physical barriers to keep them out.

Attic Restoration & Insulation

Pests destroy insulation and leave dangerous waste behind. We completely remove contaminated materials, sanitize your attic, and install brand new insulation under one roof.

Expert Mice & Rodent Control

Mice and rats are more than just a nuisance—they are incredibly destructive. They squeeze into gaps as small as a dime, chewing through structural wood, tearing up insulation for nesting material, and gnawing on electrical wires, which creates a serious fire hazard. Most pest companies just trap the mice and leave. At The Cozy Penguin, we handle the entire problem. We remove the rodents, identify exactly how they are entering, seal off your home with permanent barriers, and pull out any ruined, contaminated insulation so your home is safe and sanitary again.

Full-Service Cleanup

Our Complete Attic Restoration Process

When rodents or bats invade, they ruin your attic insulation. We are equipped to handle the cleanup and replacement from start to finish.

  1. Pest Removal and Exclusion: We safely and humanely remove the active pests and install exclusion devices so they can leave but can't get back in.
  2. Sanitization and Cleanup: We treat the area to neutralize odors, clean up hazardous droppings, and eliminate pheromones that attract new pests.
  3. Contaminated Insulation Removal: Using commercial vacuums, we safely extract all ruined, soiled insulation from your attic.
  4. Air Sealing: Before new insulation goes in, we aggressively air seal any hidden gaps, cracks, and top plates to improve home efficiency and block future pests.
  5. New Insulation Installation: Finally, we install fresh, high-performance insulation, restoring your home’s comfort and energy efficiency.

A Note on Bats in Central PA

Bats in the attic are a serious issue. Bat colonies leave behind guano that heavily saturates insulation and creates severe health risks, including histoplasmosis. Because of these risks—and strict Pennsylvania regulations that prohibit bat removal during the June-August maternity season—this is not a DIY job. The Cozy Penguin safely handles the legal exclusion, expert guano cleanup, and complete insulation remediation from start to finish.

Frequently Asked Questions

How much does rodent and wildlife exclusion cost?
The cost depends on the size of your home, the type of pest, and the extent of any insulation damage. That's why we start with a free inspection — once we've seen your home and attic, we give you an accurate, upfront quote with no obligation.
Do you spray chemicals in the house?
No. The Cozy Penguin focuses entirely on safe, physical exclusion and barrier methods to keep pests out. We do not apply or spray chemical insecticides indoors, prioritizing permanent sealing over temporary chemical fixes.
How soon can you come out?
We serve the greater Harrisburg area and can often schedule a free inspection within the same week. For urgent problems like rodents in the walls or bats in your living space, let us know — we'll do our best to prioritize your visit.
Why do I need to replace my insulation after a pest problem?
Rodents and bats leave behind large amounts of urine, droppings, and pheromones. These ruin the insulating properties of the material, create severe health risks like histoplasmosis, and the lingering smells attract new pests to your home. Complete removal is the only way to be safe.
What areas do you serve?
