What does it mean if you see a rat in your yard?

Seeing a rat in your yard can mean several things and does not automatically mean you have a large infestation inside your home, but it should be taken as a warning sign to inspect and take preventive action. A single rat in the yard could be a lone forager passing through from a nearby area, especially if you live near fields, sewers, wooded areas, or other homes, attracted by food sources like bird feeders, pet food left outside, fallen fruit from trees, compost piles, garbage cans that are not sealed, or water sources like pet bowls and leaky hoses. However, rats live in colonies and burrow, so seeing one rat during the day, which is unusual because rats are nocturnal, or seeing droppings, burrow holes near foundations, gnaw marks, and greasy rub marks along fences and walls, suggests there may be more nearby and possibly a nest in your yard, under sheds, in woodpiles, or in dense vegetation. Rats are attracted to shelter like overgrown shrubs, ivy, woodpiles, and clutter. If you see a rat in your yard, you should remove food attractants by securing trash in sealed bins, bringing pet food inside, cleaning up fallen fruit, trimming vegetation away from the house, storing firewood away from walls, and sealing entry holes larger than half an inch around your home's foundation, vents, and doors to prevent them from moving inside. Setting traps outside can help monitor.
