Rats stay around a home when they can find food, water, and shelter. The most durable approach is to remove those resources, restrict access, and monitor activity; chasing visible animals or scattering poison without correcting the environment does not solve why they are there.
Remove accessible food and water
Store pet food and bird seed in resistant containers, pick up fallen fruit, and secure trash. Repair leaks and avoid leaving food bowls out overnight when activity is present.
Reduce shelter next to the building
Move firewood, boxes, and dense vegetation away from walls and foundations and remove clutter that provides cover. Keeping a visible strip around the building makes burrows and travel routes easier to detect.
Find and correct entry points without trapping animals inside
Inspect ground-level gaps, garage doors, vents, and utility penetrations. Before sealing an active opening, make sure animals are not trapped inside and use gnaw-resistant materials without blocking ventilation or drainage.
Persistent activity near occupied areas may need professional control
Heavy fresh droppings, active burrows, or rats entering the building justify targeted control. Prioritize exclusion, sanitation, and legal, safe methods while avoiding secondary hazards to children, pets, or wildlife.
