About Rats
Rats are one of the most destructive pests found in Arizona homes. They invade attics, garages, wall voids, sheds and outdoor storage areas.
Once inside, they chew electrical wires, contaminate food, damage insulation and create constant noise at night. Rats reproduce quickly, so a small problem can become a full infestation within weeks if left untreated.

Common Rats Found in Arizona Homes
Arizona homes typically experience infestations from two main rat species:
Roof Rat
A slender, agile rat species that climbs stucco walls, trees, fences and power lines. Roof rats commonly enter attics and rooftops.
More info: roof rats on Wikipedia.
Norway Rat
A larger, stronger burrowing rat that nests in soil, foundations, crawlspaces and basements.
More info: Norway rats on Wikipedia.
Roof rats are the most common in Phoenix metro neighborhoods, especially areas with citrus trees, older homes or dense landscaping.
Where Rats Hide in Arizona Homes
Rats prefer dark, warm and quiet places where they can nest undisturbed. Common hiding areas include:
- attics and insulation
- garage shelves and storage corners
- wall voids and crawlspaces
- behind refrigerators or water heaters
- pool equipment boxes
- rooftop gaps and eaves
- block wall voids
Roof rats often enter from overhead access points, while Norway rats push in through ground level openings or burrows.
Signs You Have a Rat Infestation
- scratching, running or chewing noises in the attic at night
- droppings in garages, pantries or storage areas
- chewed electrical wires or damaged insulation
- grease marks along walls or pipes
- urine smell in enclosed rooms or attics
- fruit disappearing from citrus trees
- holes chewed into food packaging
If you hear noises at night or find droppings, the colony may already be established.
Why Rats Are Common in Arizona
Rats thrive in Arizona neighborhoods because of:
- mild winters that allow year round breeding
- irrigated yards and landscaping that attract rodents
- citrus trees that provide steady food sources
- tile roofs and attic voids that offer nesting sites
- dense suburban neighborhoods with shared access points
Once rats find a food source or shelter, they rarely leave on their own.
Are Rats Dangerous?
Yes. Rats pose serious health and property risks. They can:
- contaminate food and surfaces with bacteria
- carry fleas, mites and parasites
- spread diseases such as leptospirosis and salmonella
- cause electrical fires by chewing wires
- damage insulation, siding and stored items
The smell from rat urine and droppings can spread quickly throughout a home and attract more pests.
DIY Rat Control vs Professional Rodent Removal
DIY traps or repellents often fail because rats are cautious and avoid new objects. They also travel through hidden routes that homeowners cannot see. Removing a rat colony requires:
- accurate identification of entry points
- strategic trap placement
- inspection of attics and wall voids
- removing contaminated nesting material
- sealing openings so rats cannot re-enter
Fromms Pest Control follows a full rodent removal program that includes trapping, follow ups and entry point detection. Learn more on our rodent control service page.
How Rats Enter Arizona Homes
Rats squeeze through holes as small as a quarter. They enter through:
- gaps in roof tiles and eaves
- AC or dryer vent openings
- utility line gaps in stucco or block walls
- garage door gaps
- foundation cracks
- holes around outdoor pipes
Roof rats often climb trees or fences to access rooftops and slip through attic gaps.
Rat Prevention Tips
- trim tree branches away from the home
- seal openings around utilities
- store pet food in airtight containers
- pick up fallen citrus under trees
- clean garage clutter and storage piles
- repair irrigation leaks or standing water areas
Prevention reduces activity but does not remove rats that have already moved indoors.
