Rodent Control in Hacienda Heights

The open-space edge drives rodent pressure

The Hacienda Hills section of the Puente Hills Preserve sits inside the community. Its brush and oak cover is natural habitat for roof rats and deer mice, and in the dry months they push toward irrigated yards, avocado and citrus trees and pet food left outside.

Roof rats are climbers: they run along fence tops, utility lines and branches that touch the roof. On streets that back onto open space, we trim-and-seal at the roofline as well as at ground level.

Entry points in late-1960s construction

With a median build year of 1968, most homes here have original gable and foundation vents, low-pitched tile roofs with open eave ends, and attached garages whose door seals have worn out. A rat needs a gap about the size of a quarter; a mouse, the size of a dime.

We close openings with galvanized steel mesh, hardware cloth and metal flashing rather than foam alone, which rodents chew through. Every sealed point is photographed so you can see the work.

Rats, fleas and typhus

Los Angeles County recorded a record 220 flea-borne typhus cases in 2025. The disease spreads through fleas carried by rats, opossums and stray cats. Removing rodents and blocking wildlife from crawl spaces and attics lowers the flea load around your home — one more reason to treat a rodent problem early.
