- Noise overhead at nightHeavier scurrying or thumping in the attic after dark, especially along the roofline where roof rats travel.
- Gnawed fruit and irrigation linesHalf-eaten citrus still on the tree or on the ground, and chewed watering lines near garden beds.
- Rub marks on beamsDark greasy smudges on attic rafters or fence tops where rats repeatedly travel the same route.
- A dead-animal smellA strong odor from a wall void or attic space, often the first sign a rat died somewhere inaccessible.

Rats in San Marcos: common questions
Are rats common in San Marcos?
Escondido, Vista, and San Marcos sit in citrus and avocado country, which is close to ideal roof rat habitat with year-round food and cover. Larger inland lots often border groves that keep reintroducing rats even after a yard is cleared. If you're seeing these signs at your San Marcos home, an inspection confirms it fast.
Are roof rats more dangerous than Norway rats in San Marcos?
Roof rats are not more dangerous to health, but they are harder to control because they nest above ground in attics and trees rather than in ground burrows, which limits how well ground-level bait stations work.
Should I use poison bait for rats around my house?
We generally recommend against loose rodenticide for homeowners. It poses a risk to pets and wildlife, and a poisoned rat often dies inside a wall, creating an odor problem that is worse than the original infestation.
