Termite Season Is Underway: Why the Next Few Weeks Are Critical for North Texas Homeowners

If you've lived in North Texas for any length of time, you know our weather doesn't follow the rules. One week it's 80 degrees, the next we're dodging ice storms. But there's one thing our unpredictable climate guarantees every year: prime conditions for termite activity. And right now—late March through May—is when it hits full swing.

The North Texas Termite Calendar

Unlike other regions where termite season has a clear start and end date, North Texas homeowners face a longer window of vulnerability. Our mild winters mean termite colonies rarely go fully dormant—they just slow down. When daytime temperatures start hitting the mid-70s consistently and we get those trademark spring rains, colonies that have been quietly feeding all winter suddenly shift into reproductive mode.

Here's what's happening underground right now: Eastern subterranean termite colonies—the most common species in North Dallas—are preparing to send out swarmers. These winged reproductives typically emerge between late February and May, with peak activity in March and April. They'll swarm during the day, usually in the morning hours, often within 24 to 48 hours after a good rain.

Why Your Neighbor's Problem Could Become Yours

Here's something most homeowners don't realize: termite colonies don't respect property lines. A single subterranean termite colony can forage across an area the size of a football field—workers have been documented traveling over 300 feet from their nest. When that colony sends out swarmers, they're looking to establish new colonies—and your home is just as appealing as any other structure in the neighborhood.

If your neighbors have had termites, or if homes in your subdivision were built around the same time with similar construction methods, your risk level increases. Multiple colonies often exist in the same area, and Texas A&M AgriLife Extension notes that Texas is one of the most at-risk states for termite infestations due to our warm, humid climate.

The Real Estate Factor

Spring is also peak home-buying season in DFW, and termites can throw a wrench into real estate transactions. Texas law requires sellers to disclose known termite damage, and most lenders require a Wood Destroying Insect (WDI) report before closing. If you're planning to sell this year, discovering an active infestation during the buyer's inspection can delay closing, reduce your sale price, or kill the deal entirely.

On the flip side, if you're buying a home, don't rely solely on the seller's inspection. Get your own WDI report from a company that will be around to back up their findings. A thorough inspection now can save you from inheriting someone else's termite problem.

What Makes Right Now Different

Late March through early May sits at a critical intersection in the termite calendar. Colonies that have been feeding through winter are at their strongest. Soil temperatures are rising, triggering reproductive behavior. And our typical spring weather pattern—warm days followed by afternoon or evening storms—creates ideal swarming conditions.

This is also when baiting systems are most effective. Termites are actively foraging and more likely to discover and feed on bait stations. If you've been putting off termite protection, waiting until summer means missing the window when preventative measures work best.

Your Spring Action Plan

Now through April: Schedule a professional inspection before swarm season peaks. This is the time to install or check existing monitoring stations. Early detection means simpler, less expensive treatment.

April-May: Peak swarming season. If you see winged insects inside your home—especially near windows after a rain—don't ignore them. Collect a sample and call for identification immediately.

June-August: Colonies are actively feeding and growing. Existing baiting systems are working hardest during these months. Maintain your monitoring schedule.

September-February: Activity slows but doesn't stop. This is a good time for preventative treatments if you missed the spring window, and for addressing any moisture or structural issues that make your home more vulnerable.

Now is the time to act—not after you see swarmers. Call Bug Zone at (972) 867-9800 to schedule your inspection before peak swarming season hits.
