Rats in National City: common questions
Are rats common in National City?
Canyon edges running through the city core and La Mesa carry wild rat populations into adjacent neighborhoods, and untrimmed palm trees common in older Central San Diego yards are a favorite roof rat highway straight to the roofline. If you're seeing these signs at your National City home, an inspection confirms it fast.
Are roof rats more dangerous than Norway rats in National City?
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.
