Key Takeaways
- 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.

Frequently Asked Questions
Can I reuse insulation after a squirrel infestation?
No. Contaminated insulation should be removed and replaced. Squirrel urine and droppings can carry diseases, and the insulation loses its R value when soiled.
How do I fix wires chewed by squirrels?
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.
Does homeowners insurance cover squirrel damage?
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.
How much does professional attic restoration cost?
Professional attic cleanup and restoration after a squirrel infestation typically costs $500 to $3,000. DIY restoration costs $100 to $400 in materials.
