Buying a home in the Phoenix Valley comes with unique pest considerations. The desert climate
creates year-round pest pressure, and while many buyers carefully review home inspection
reports, pest-specific risks are often overlooked. This is true for both new construction and
resale homes. Understanding what to watch for can help buyers avoid costly surprises after
closing.
This guide highlights common pest red flags and explains why proactive inspections are an
essential part of buying a home in Arizona.

Why Pest Inspections Matter in Arizona Real Estate

Standard home inspections do not always catch pest-related issues. Termite activity, rodent
entry points or early infestations can be missed if inspections are not pest-focused. In Arizona,
termite inspections are especially important, as early detection can prevent expensive structural
repairs after closing.

Termites: The #1 Concern in the Valley

A common saying among real estate professionals is, “It’s not if you get termites–it’s when,”
reflecting the pervasiveness of these pests in the Phoenix Valley.

What Buyers Should Look For

● Mud tubes along foundations, stem walls or garage walls
● Wood damage, bubbling paint or hollow-sounding trim
● Evidence of past termite treatment, such as drill marks in slabs or treatment tags

New Build Considerations

● Was the home pre-treated during construction?
● Has the soil been disturbed after treatment due to landscaping or pool installation?
● Is there wood-to-soil contact around the structure?

Resale Home Considerations

● When was the last termite treatment or inspection completed?
● Does the home have a history of previous termite infestations?
● Are there any visible signs of untreated damage in older homes?

Roof Rats and Other Rodents

Roof rats and other rodents are common in certain parts of the Valley.

Signs to Watch For

● Droppings in attics or garages
● Chewed wires or damaged insulation
● Scratching noises reported by sellers
● Citrus trees or dense landscaping near the roofline

New Build Risks

● Construction debris left in attic spaces
● Gaps in roof tiles or damaged vent screens
● Developing neighborhoods near open land
Resale Home Risks
● Mature trees creating “bridges” to the roof
● Previous rodent entry points that were not properly sealed

Scorpions

Scorpions are another common household pest in the Phoenix metropolitan area.Why They’re Common in Arizona Homes

● New development disrupts desert habitats

● Irrigated landscaping attracts insects, which scorpions feed on
What Buyers Should Check
● Gaps under doors and around windows
● Cracks in foundations or block fencing
● Rock landscaping and clutter near the home

New Construction Hotspots
● Homes near desert preserves or open land
● Recently developed communities with higher scorpion activity

Cockroaches

Another pest that causes homeowners alarm is cockroaches.

Warning Signs

● Droppings that resemble pepper or coffee grounds
● Musty odors in kitchens or bathrooms
● Activity under sinks or behind appliances

New Builds

● Cockroaches can be introduced during construction or move-in
● Drain systems may harbor American cockroaches

Resale Homes

● More common in older plumbing systems
● Higher risk in multifamily or high-density neighborhoods

Ants and Other Nuisance Pests

Termites, rodents, scorpions and cockroaches aren’t the only pests to watch out for.

● Fire ant mounds in yards
● Odorous house ants entering kitchens
● Crickets, which can attract scorpions

Yard and Landscaping Red Flags

The home’s landscaping can give you clues into future pest problems you may encounter.

● Over-irrigation near the foundation
● Wood piles or debris against the home
● Thick shrubs touching exterior walls
● Poor drainage causing moisture buildup

Questions Buyers Should Ask Sellers or Builders

When buying a home, be sure to ask the seller (or the builder of new construction) the following
questions:

● Is there a current pest control service in place?
● When was the last termite treatment or inspection?
● Is there any history of rodent or scorpion activity?
● Are pest warranties transferable?

Why New Homes Still Need Pest Control

“Brand new” does not mean pest-free. Construction disturbs pest habitats, and gaps or settling
can create entry points during the first year. New homes still require routine pest prevention and
inspections.

Protecting Your Investment After Purchase

Once you secure your dream home, these steps can help prevent pests from becoming your
nightmare.

● Start routine pest control immediately

● Schedule annual termite inspections
● Seal and maintain the home’s exterior
● Monitor landscaping and irrigation carefully

When to Call a Professional Before Closing

If you have any doubts before putting in an offer, a professional pest control inspection can help
provide peace of mind.

● Visible pest activity or suspicious damage
● Homes near desert preserves, canals, or greenbelts
● Properties without recent termite protection

Pest awareness is a key part of smart home buying in the Phoenix Valley. Both new and resale
homes carry pest risks, and proactive prevention helps protect property value and peace of
mind.
