If you’re a homeowner in Arizona, termites aren’t a maybe problem, they’re a when problem. Thanks to our warm climate and mild winters, termite activity is common across Phoenix, Tempe and surrounding areas.

If you’ve ever asked yourself, “How do I know if I have termites in my house?” this checklist is for you.

When Is Termite Swarm Season in Phoenix?

In the Phoenix area, termite swarm season typically happens between February and May, depending on weather conditions. Swarms usually appear:

• After warm days
• Following rainfall or increased moisture
• During calm evenings

Swarming termites are often mistaken for flying ants, but they’re a sign of something much more serious: A mature termite colony nearby or inside your home.

What Is a Termite Swarm (and Why It Matters)?

A termite swarm is when winged termites (called swarmers) leave their colony to start new ones. Seeing swarmers indoors is especially concerning and should never be ignored. While the swarm itself is short-lived, it’s a warning sign that:

• A colony is already established
• There may be hidden damage
• The infestation could grow quickly if untreated

Homeowner Checklist: Signs You May Have Termites in Arizona

1. Flying Termites Inside or Near Windows

Swarmers are attracted to light and are often found near windows, doors, or light fixtures. If you see them indoors, it’s time to act.

2. Discarded Wings

After swarming, termites shed their wings. Finding small piles of clear or milky wings on windowsills or floors is a classic sign of termites in Phoenix homes.

3. Mud Tubes on Walls or Foundation

Subterranean termites (the most common type in Arizona) build pencil-sized mud tubes along foundations, walls, or garages to protect themselves from dry air.

4. Hollow or Damaged Wood

Wood that sounds hollow when tapped or crumbles easily could indicate termite damage beneath the surface, Even if everything looks fine from the outside.

5. Tight Doors or Windows

Termites introduce moisture as they tunnel through wood, which can cause doors and windows to warp or stick unexpectedly.

Why Termites Are So Common in Phoenix Homes

Arizona’s environment is basically a termite paradise. Even well-maintained homes can have termites without obvious signs. Here is why termites are so common in the Phoenix Metro area:

• Warm temperatures year-round
• Expansive soil that supports subterranean colonies
• Irrigation systems and moisture near foundations
• Older and newer homes alike at risk

What To Do If You Suspect Termites

• Don’t disturb the area (sprays won’t solve the problem)
