Raccoons in the Attic: Electronic Deterrents as a Supplement to Trapping

Situation: Raccoons in Attic of New Home

One caught by animal control; others likely remain. Entry point identified.

Electronic Deterrents: Role and Limits

• Devices (e.g., Walnut Creek Enterprises) emit sonic/ultrasonic/strobe to discourage approach.
• Place outside near entry point to deter re-entry.
• Not a standalone solution—will not evict established animals.

Required Steps

1. Confirm all animals removed (trapping, one-way door).
2. Seal entry permanently with hardware cloth/metal flashing.
3. Repair damage (insulation, wires, droppings cleanup).
4. Use electronic deterrent after exclusion to prevent new attempts.

Legal/Safety Note

Raccoons carry rabies, roundworm. Never handle. Hire licensed wildlife control operator for removal and exclusion.
