Quick tips

Each year when we change our clocks, after you've checked the batteries in your smoke detectors, check the exterior of your home for obvious rodent entry points. Repair any attic and subarea vent screens that are missing or damaged. To find more information on how to prevent rodents from coming into your home click here.
