California is home to a diverse array of rodents, from tiny mice to bulky beavers. While many species live exclusively outdoors, several have adapted to take advantage of the shelter and food provided by human homes. According to Birdwatchinghq.com, the most frequent offenders that invade households throughout the state include the House Mouse, Roof Rat, Norway Rat, Deer Mouse, and House Sparrows.
These resourceful rodents locate even the smallest gaps and cracks to enter attics, basements, walls, and living areas. Once inside, they contaminate food, destroy insulation, and spread parasites. An infestation of these destructive pests can be stressful and expensive to eliminate. The key is prevention through exclusion techniques before they ever gain access to your home.
House mice enter through even smaller gaps than rats and reproduce rapidly once established. Squirrels occasionally nest in attics in neighborhoods with mature tree canopy, particularly in older communities in Fullerton, Orange, and Tustin. Each species requires a different exclusion approach. Attic Projects identifies which species is present during our free inspection and tailors the exclusion plan accordingly.
Orange County is home to several rodent species that invade residential attics and crawl spaces. Roof rats are the primary attic pest, traveling along power lines, tree branches, and fence tops to access rooflines. Norway rats are more common in crawl spaces and ground-level entry points, particularly in areas near water sources and commercial districts.
Norway Rats (Rattus norvegicus) enter homes through any openings at ground level. They live in burrows around foundations, sewers, etc.
Deer Mice (Peromyscus maniculatus) sometimes enter homes in rural areas or where homes back up to wildland areas. They can be carriers of hantavirus.
House Sparrows (Passer domesticus) are common invaders of holes in eaves, vents, and around edges of windows. They build messy nests and can damage insulation. The best defense against household rodents is prevention through professional rodent-proofing. By sealing up potential entry points and removing exterior rodent attractions, you can stop these pests from ever entering your home. Our rodent-proofing service identifies and blocks their secret access routes, removing any food, water, or shelter. Don’t wait until you have an infestation to take action. Be proactive and rodent-proof your home today! Our effective rodent deterrent service provides lasting results you can enjoy for years to come.

DIY rodent control and monthly pest control services treat symptoms without solving the underlying problem. Traps and poison reduce the current population but do nothing to prevent new rodents from entering through the same gaps. Attic Projects takes a structural exclusion approach: we identify and seal every entry point on your home’s exterior, from foundation vents to roofline gaps, using steel mesh, metal flashing, and expanding foam that rodents cannot chew through. This is why we offer a 10-year warranty against rodent re-entry, and pest control companies do not.
Attic Projects has performed rodent proofing on thousands of Orange County homes since 2016. Our exclusion process includes a full exterior inspection, sealing of all identified entry points, trapping and removal of existing rodents, and complete attic cleaning to remove droppings and contaminated insulation. Every project is backed by a 10-year warranty covering both workmanship and rodent re-entry.
Rodent proofing alone does not restore your attic to a safe condition. After exclusion, Attic Projects performs complete attic restoration that includes removing contaminated insulation, sanitizing all surfaces with EPA-registered antimicrobials, repairing rodent-damaged wiring and ductwork, and installing new insulation to current code standards. This full-scope approach eliminates health hazards, restores energy efficiency, and prevents the conditions that attracted rodents in the first place. Our insulation removal and replacement services are included in our complete rodent proofing packages.
