Summer in Arizona means backyard barbecues, pool days, and unfortunately, increased termite activity. While many homeowners associate termites with spring, Arizona’s second termite swarming season typically runs from July through September, making this one of the most important times of year to inspect your home.
If you’re researching termite control in Surprise AZ or termite treatment in Surprise AZ, knowing what warning signs to look for can help you catch a problem before it turns into expensive structural damage.
Many homeowners are surprised to learn that some areas of Arizona may have up to 20 subterranean termite colonies per acre. That means even if you’ve never had termites before, there may already be multiple colonies living beneath the soil surrounding your property.
Here are eight signs your home may need professional termite control this summer.
1. You See Winged Termites Around Your Home
One of the most obvious warning signs is the appearance of winged termites, also known as swarmers.
Arizona experiences two major termite swarming seasons:
- March through May
- July through September
Swarmers leave mature colonies in search of new places to establish nests.
If you see swarmers around your windows, doors, garage, or outdoor lights, don’t ignore them. Even if they disappear after a day or two, a mature colony may already be nearby.
Professional termite control in Surprise AZ can help determine whether swarmers are coming from your property or a nearby colony.
2. You Find Discarded Wings
After swarmers land, they shed their wings.
Finding small piles of identical wings near windowsills, sliding glass doors, garages, or patios often indicates termite activity nearby.
Many homeowners mistake these wings for debris and simply clean them up without realizing they may be an early warning sign.
3. Mud Tubes Appear Along The Foundation
Subterranean termites build mud tubes to protect themselves while traveling between the colony and your home.
Mud tubes are commonly found on:
- Stem walls
- Foundation walls
- Garage walls
- Stucco surfaces
- Block fencing
If you discover mud tubes, avoid removing them until they’ve been inspected. They can help determine whether the infestation is active.

4. Wood Sounds Hollow
Termites eat wood from the inside out.
Because of this, wood may appear normal on the surface while being heavily damaged internally.
If trim, baseboards, window frames, or door frames sound hollow when tapped, it may be time for a professional inspection.
5. Your Home Has Never Been Treated
Many homeowners assume that because they have never seen termites, they don’t need protection.
The reality is Arizona has some of the highest subterranean termite pressure in the country.
With approximately 20 termite colonies per acre in some locations, every untreated home is exposed to termite activity.
Routine inspections help identify activity before damage becomes extensive.
6. You Are Relying Only On Bait Stations
Many homeowners ask whether bait stations are enough.
While bait stations can work in certain situations, they also have limitations.
Bait stations require termites to locate and feed on the bait before control begins.
Arizona’s irrigation systems, monsoon moisture, and poor drainage can sometimes allow mold to develop inside bait stations. When mold develops, termites may avoid feeding on the bait, reducing effectiveness.
Because termite pressure is already so high throughout Arizona, many homeowners prefer a treatment that protects the entire structure.
7. The Colony Continues Growing Underground
One reason termites are so difficult to eliminate is because homeowners rarely see the colony itself.
A subterranean termite queen can live as deep as 25 feet underground and may lay approximately 300 to 500 eggs every day.
As long as the queen remains alive, the colony continues producing worker termites that search for food.
That is why simply killing visible termites rarely solves the problem.
8. You Want Long-Term Protection
Many homeowners choose Termidor HE because it helps eliminate termites at the source.
Rather than waiting for termites to discover bait, Termidor HE creates a treated zone around the structure.
As termites move through the treated soil, they transfer the product throughout the colony, helping eliminate termites they never directly contacted.
Professional termite treatment in Surprise AZ using Termidor HE provides long-term protection and remains one of the most trusted treatment methods for Arizona homes.

Why Summer Is The Best Time To Schedule An Inspection
Arizona’s second swarming season has begun.
Waiting until visible damage appears often means termites have already been active for months or even years.
Scheduling an inspection now allows homeowners to identify activity before structural damage becomes more extensive.
Routine inspections are one of the best ways to support long-term termite control in Surprise AZ and help protect your home’s value.
