Squirrel in the Attic: Why Repellents Fail and What Works

Home remedies like cedar oil, garlic, cayenne pepper, mothballs, ultrasonic devices, and radios are largely ineffective for evicting squirrels from an attic. Mothballs are especially dangerous—their vapors are toxic to humans and pets.

The only reliable solution is hiring a licensed wildlife control professional to trap and remove the animal and, crucially, seal all entry points permanently. Prevention is far cheaper than repair.
