After evicting squirrels from your attic or walls, the real work begins. Squirrels leave behind chewed wires, torn insulation, droppings, and urine soaked materials that create health hazards and fire risks. Using the right repair supplies ensures your home is safe, clean, and fully restored.
Learn the process step by step in my insulation repair guide. I compared the best products for attic cleanup after squirrel infestation, wire repair, insulation restoration, and odor removal using manufacturer specifications and published reviews.
- Safety first: Always wear an N95 respirator and gloves before entering a squirrel infested attic. Dried droppings and urine can release harmful particles and bacteria.
- Enzyme cleaners eliminate odors permanently: Bio enzymatic cleaners break down urine proteins at the molecular level, removing odors that would otherwise attract other wildlife to the same spot.
- Heat shrink tubing is the only safe wire repair method: Standard electrical tape fails over time. Use heat shrink tubing for permanent insulation on chewed wires.
- Seal repairs before restoring insulation: Always seal every entry point with hardware cloth and rodent block foam before installing new insulation, or squirrels will return.

- Remove contaminated insulation: Bag and dispose of all soiled material
- Clean all surfaces: Spray enzyme cleaner on wood, beams, and concrete
- Allow to dry: Wait 24 to 48 hours for enzyme cleaner to fully work
- Repair chewed wires: Use heat shrink tubing to re insulate damaged wiring
- Seal every entry point: Install hardware cloth, Xcluder, and rodent foam
- Install one-way exclusion doors: If any squirrels may still be inside
- Replace insulation: Install new R value batts or blown in insulation
Frequently Asked Questions
No. Contaminated insulation should be removed and replaced. Squirrel urine and droppings can carry diseases, and the insulation loses its R value when soiled.
For minor damage where the wire is not severed, use heat shrink tubing to re insulate. For severed wires or major damage, call a licensed electrician. Never use standard electrical tape for long term repairs.
Many policies cover squirrel damage to electrical wires and insulation if it is sudden and accidental. Check with your provider. Damage from gradual infestation may not be covered.
Professional attic cleanup and restoration after a squirrel infestation typically costs $500 to $3,000. DIY restoration costs $100 to $400 in materials.
Yes. Squirrel droppings, urine, and nesting material contaminate insulation and can carry parasites and disease. Spot clean small areas, but heavy contamination usually means replacing the affected insulation rather than reusing it.
Repair entry points only after you are certain all squirrels are out, using a one-way door first or confirming activity has stopped. Sealing while squirrels are still inside traps them and leads to worse damage, odor, and a dead animal in the wall.
