Rats are excellent climbers and often enter a home in the fall when outside food sources become scarce.


Control / Prevention

Keep firewood stored well away from the structure. Remove debris piles. Seal any holes larger than 1/4 inch. Remove moisture and harborage sources.


Rats can chew through wiring, causing fires. They also spread numerous diseases.
