Sasquatch Pest Control | 281-627-4810 | Serving Greater Houston & Harris County
A lot of Houston homeowners assume termites are only a springtime worry, when the big swarms happen. The reality is that termites stay active year-round in our climate — they simply become less visible after spring. Underground, subterranean and Formosan termite colonies keep feeding through fall and winter, quietly consuming wood inside homes across Harris County. Fall is actually one of the smartest times to inspect and protect your home, because you’re catching damage before it compounds and getting ahead of next spring’s swarm season.
At Sasquatch Pest Control, termites are one of the pests we take most seriously, because the damage is expensive, largely hidden, and usually not covered by homeowner’s insurance. Here’s what fall termite activity looks like in the Houston area and how to stay protected.
Do termites really stay active in the fall in Houston?
Yes. In colder climates, termite activity slows dramatically as the ground cools. Here on the Gulf Coast, our mild temperatures and high soil moisture keep subterranean termites feeding well into fall and through much of winter. The colony doesn’t shut down — it stays underground, sheltered from temperature swings, and continues sending workers up into the wood of homes and structures.
What changes in fall is visibility. The dramatic spring swarms of winged reproductives — the event most people associate with termites — are largely over. That absence lulls homeowners into thinking the threat has passed. In truth, the quietest months are when a lot of damage accumulates, precisely because nobody’s looking.
What kinds of termites do Houston homes deal with?
Native subterranean termites
Eastern subterranean termites are the most widespread termite in the region. They live in underground colonies and reach wood by building distinctive mud tubes — pencil-width tunnels of soil and saliva — up foundations, piers, and walls. They feed on the softer spring wood within lumber, hollowing boards from the inside out while leaving a thin surface intact, which is why the damage stays hidden for so long.
Formosan termites — the aggressive threat
Houston is squarely within the range of the Formosan subterranean termite, often called the most destructive termite in the country. Formosan colonies are enormous — potentially numbering in the millions — and they feed faster and more aggressively than native species. They can also build nests called cartons inside wall voids and other above-ground spaces where moisture is available, meaning they don’t always need soil contact. A Formosan infestation can cause significant structural damage in a fraction of the time a native colony would take, which is exactly why fall vigilance matters here more than in most parts of the country.
Why this matters in Houston: The presence of Formosan termites raises the stakes considerably. Their speed and colony size mean a problem that goes unnoticed through fall and winter can become serious structural damage by spring. Early detection is everything.
What are the warning signs of termites in the fall?
Because termites work out of sight, you have to know what to look for. Watch for these signs around your Houston home:
- Mud tubes — pencil-thin tunnels of dried soil running up foundation walls, piers, or in the crawl space or garage.
- Hollow-sounding or soft wood — tap baseboards, door frames, and trim; termite-damaged wood sounds hollow and may feel spongy.
- Discarded wings — small piles of translucent, equal-length wings near windowsills, doors, or light sources, left behind by swarmers.
- Bubbling, blistering, or peeling paint — often mistaken for water damage, this can indicate termites tunneling just beneath the surface.
- Frass (drywood termite droppings) — tiny wood-colored pellets, though subterranean species are more common here.
- Tight-fitting doors and windows — as termites damage and warp wood, frames can start to stick.
- Small holes or crumbling wood in structural timbers, decks, fence posts, and door jambs.
What attracts termites to a Houston home?
Termites need three things: wood (or other cellulose), moisture, and access. Reducing those conditions makes your home far less inviting. Common attractants around Houston-area properties include:
- Moisture against the foundation from poor drainage, leaky faucets, AC condensation, or downspouts dumping next to the house
- Wood-to-soil contact — deck posts, fence pickets, stair stringers, and siding in direct contact with the ground
- Mulch and wood debris piled against the foundation, and firewood stacked against the house
- Clogged gutters that keep soffits and fascia damp
- Crawl space and slab moisture that gives subterranean termites the humidity they need
- Tree stumps, buried scrap wood, and old form boards left near or under the structure
How can I reduce my termite risk this fall?
Fall is a natural time to knock out the moisture and wood-contact issues that draw termites, since you’re already thinking about yard cleanup and getting the house ready for cooler weather. Focus on:
- Fix drainage and leaks. Direct downspouts away from the foundation, repair dripping faucets and AC lines, and correct low spots that hold water.
- Break wood-to-soil contact. Keep siding, deck posts, and fence pickets from touching bare ground where possible.
- Move wood away from the house. Store firewood off the ground and away from the structure, and clear mulch, scrap lumber, and debris from the foundation.
- Keep gutters clear so water doesn’t sit against the roofline and walls.
- Ventilate crawl spaces and address standing moisture underneath the home.
- Schedule a professional inspection to catch anything already underway.
Important: Prevention lowers your risk, but it can’t detect or eliminate an active colony. Only a thorough inspection can confirm whether termites are already present — and with Formosan termites in the area, that confirmation is worth having before winter.
Why is a fall termite inspection worth it?
Termite damage compounds. Every month an infestation goes undetected, workers remove more wood and the eventual repair grows more expensive. A fall inspection catches active termites and hidden damage before winter, gets protection in place, and puts you ahead of the spring swarm — when new colonies establish and existing ones expand.
It’s also about peace of mind and protecting one of your largest investments. Because termite damage is typically excluded from homeowner’s insurance, the cost of ignoring a problem falls entirely on you. A professional inspection is a small, sensible step to make sure a quiet fall isn’t hiding an expensive spring surprise.

If you’re in Houston, Spring, Tomball, or anywhere in Harris County and it’s been a while since your last termite check, fall is the right time to take care of it.
Frequently Asked Questions
Are termites active in the fall, or just in spring?
They’re active year-round in Houston. Spring is when the visible swarms happen, but subterranean and Formosan termite colonies keep feeding through fall and winter thanks to our mild temperatures and moist soil. The colony doesn’t shut down — it just becomes less visible. That’s actually why fall matters: a lot of hidden damage accumulates in the months when homeowners assume the threat has passed.
Why are Formosan termites such a big deal in Houston?
Formosan subterranean termites are often called the most destructive termite in the country. Their colonies can number in the millions, they feed faster and more aggressively than native species, and they can even nest above ground inside wall voids where moisture is available. Because Houston is within their range, an infestation that goes unnoticed through fall and winter can cause serious structural damage by spring — making early detection critically important here.
What are the earliest signs of termites I should look for?
Watch for pencil-thin mud tubes running up foundation walls or piers, wood that sounds hollow or feels soft when tapped, small piles of discarded translucent wings near windows and doors, and paint that bubbles or blisters like water damage. Doors and windows that suddenly stick can also signal wood damage. Because termites work out of sight, these subtle clues are often the only warning before a professional inspection.
What around my house attracts termites?
Termites need wood, moisture, and access. Common attractants include moisture against the foundation from poor drainage or leaks, wood-to-soil contact from deck posts and fence pickets, mulch and firewood piled against the house, clogged gutters keeping the walls damp, and crawl space or slab moisture. Reducing these conditions makes your home far less inviting, though it won’t eliminate a colony that’s already established.
Can I prevent termites myself, or do I need a professional?
You can meaningfully lower your risk by fixing drainage and leaks, breaking wood-to-soil contact, moving firewood and mulch away from the house, and keeping gutters clear. But prevention can’t detect or eliminate an active colony — only a thorough inspection can confirm whether termites are present, and treating an established infestation (especially aggressive Formosans) requires professional products and methods. Prevention plus a professional inspection is the reliable combination.
Does homeowner’s insurance cover termite damage?
Generally no. Termite damage is typically excluded from standard homeowner’s policies because it’s considered a preventable maintenance issue rather than a sudden accident. That means the full cost of repairs falls on you if an infestation is ignored — which is exactly why a modest investment in a fall inspection and protection is so worthwhile. Catching termites early is far cheaper than repairing months of hidden structural damage.
Do you offer termite inspections in the Houston area?
Yes. We provide free termite inspections throughout Houston, Spring, Tomball, Shenandoah, Aldine, Jersey Village, and the surrounding Harris County communities. We check for mud tubes, wood damage, and the moisture and wood-contact conditions that invite termites, then give you honest options if we find anything — no contracts, no scare tactics, and everything backed by our 100% service guarantee.
