How to get rid of rats in Coronado, CA
Roof rats thrive in San Diego County thanks to mild winters, mature landscaping, and citrus trees that offer food and cover year-round. They travel along power lines, fences, and palm fronds, then drop into attics through gaps at the roofline.
What you're dealing with in Coronado
Roof rats (black rats) dominate San Diego neighborhoods with mature trees, while Norway rats show up more in ground-level burrows near irrigation and trash areas.
Coronado homes sit in salt air and marine humidity 24/7, ideal conditions for drywood termites, brown widows under stucco overhangs, and roof rats in mature palms. The pre-1950 Spanish Colonial and Craftsman stock through the Village and along Ocean Boulevard needs annual termite inspections, not biennial.
Why rats show up here
Older beach neighborhoods in Point Loma and Coronado have mature landscaping and tight lot spacing that gives roof rats easy travel routes between yards. Salt-air weathering on older roof edges creates small gaps that add up over time.
How to get rid of rats: step by step
- Trim trees away from the roofline Cut back branches, especially citrus and palm, that touch or come within a few feet of the roof. This is the single biggest access point for roof rats.
- Use snap traps in the attic and along fence lines Rat-sized snap traps baited with peanut butter or nesting material work better outdoors than poison, which can leave a dead rat somewhere you cannot reach.
- Secure trash and compost Rats forage at night for anything left in unsecured bins. Tight-fitting lids on trash and compost cut off an easy food source.
- Check the roofline for gaps Look at vents, eaves, and the gap where the roof meets the fascia board. A rat needs a hole about the size of a quarter to get in.
- Pick fruit promptly Fallen citrus and avocados on the ground are a major rat food source in inland yards. Clearing fruit regularly removes the incentive to stay.
When to call a pro in Coronado
Rats are harder and more dangerous to trap than mice, since bite risk is higher and they often nest in places homeowners cannot reach, like wall voids or under insulation. If you are hearing movement in the attic at night or finding rat-sized droppings, it is worth calling a pro for exclusion work and a proper trap placement plan.

Rats questions from Coronado homeowners
Are roof rats more dangerous than Norway rats in Coronado?
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.
How much does rat exclusion cost in Coronado?
Exclusion work, sealing the actual entry points into the attic and walls, typically runs $400 to $2,000 depending on how many gaps a home has and how accessible the roofline is.
