Caution: Avoid applying directly to delicate surfaces or vegetation where heavy residue could occur; test on a small area first.

It’s suitable for frequent touch-ups around doors or windows. Caution: Surfaces may require wiping if the spray leaves any residue on sensitive finishes.
Pest Rodent Repellent Peppermint Oil Balls – 24 Pack

Best for: Quick, visual, long-duration coverage in outdoor nooks and garages. The mesh-bag packaging allows placement in corners, car engines, and storage areas where rodents are common.

Caution: Replacement may be needed around very windy or heavily exposed outdoor spots to maintain effectiveness.
