Be in the Know
Learn everything you can about these critters. Are they in your area? Find out here. Roof Rats can squeeze into almost any opening, crack, or crevasse. They have an oil and dust combination on their bodies which produces a lubricating grease. This enables them to squeeze into holes as small as a ¼ inch. Play it smart– if you can stick your finger in the hole, it’s going to be a problem!
Find Out How Roof Rats Could Get In
Roof Rats can come into the home from anywhere, but they generally enter from the roof. Check the areas surrounding your ducting, chimney, ventilation, cooling, and roof work. Examine the siding and base of the house for any possible gaps that lead into the home. Front doors, back doors, pet doors, and garage doors can also be a point of entry. Verify that none of these doors have gaps in the corners or sides. Keep these doors shut whenever possible. Install screens on all windows.
Do Not Underestimate Roof Rats
Roof Rats have sharp teeth that can cut through cement, metal pipes, aluminum siding, sheetrock, drywall, wood, plastic and a variety of other materials. Seal up holes with steel. Steel wool, steel plating, and steel mesh sealed with heavy duty caulking work best. Steel feels like razor blades on roof rat teeth.
Double Check These Areas
When it comes to the interior of your home, ensure that there are no holes in the walls, baseboards, floorboards, or ceiling. The holes created by pipes or electrical cables are especially a target. Many of these holes in the walls are made by kitchen appliances like stoves and refrigerators, but water heaters and air conditioners can also create holes. Be certain that the areas around the holes are sealed up well.
