Rats control — prevention & targeted treatment
Rats are larger than mice and enter through gaps of a half-inch or more. Norway rats burrow; roof rats climb and prefer attics and trees.
Signs to look for
- Large droppings (about 3/4 inch) near food or along runways
- Gnawed wires, wood, or plastic with visible teeth marks
- Burrow holes along foundations, sheds, or compost
- Runways (rubbed, greasy paths) along walls
Prevention (starts before the pest does)
- Seal holes larger than 1/2 inch; install door sweeps
- Keep trash in sealed cans and pick up pet food
- Trim trees that overhang the roof (roof rats climb)
- Store firewood and compost away from the house
Safe DIY limits
- Seal obvious openings with hardware cloth and caulk
- Remove food and water sources outdoors and in
- Keep vegetation and clutter away from the foundation
Eco-friendly approach
Rats are handled with a combination of exclusion, trapping, and careful bait station placement — with emphasis on preventing re-entry over reliance on poison.

Common questions
Why do rats keep coming back?
Rats return when food, water, and shelter remain. Persistent problems usually trace to an unsealed entry or an attractant like pet food or open compost.
How do I know if I have rats or mice?
Size is the clue: rat droppings are much larger, and rats create heavier gnaw marks and burrows. A licensed inspection can confirm.
