Yes. Texas A&M AgriLife Extension entomologists report that invasive Formosan subterranean termites are established in Texas — concentrated in the humid southeastern part of the state, which puts Deep East Texas squarely in their range.
What is a Formosan termite?
The Formosan subterranean termite is an invasive termite species originally from East Asia. It behaves like our native subterranean termites — living in soil and tunneling into wood — but with one alarming difference: colony size. A mature Formosan colony can contain millions of termites, many times larger than a native colony, which means it can do far more damage in far less time.
Are they actually established in East Texas?
Yes. Texas A&M AgriLife Extension entomologists report that Formosan subterranean termites are established in Texas, concentrated in the warm, humid southeastern part of the state — the same conditions found across the Piney Woods. They spread through infested landscape timbers, mulch and soil as well as by swarming, which is how new counties keep getting added to the map. This is not a distant coastal problem — it is a real consideration for homes in Angelina and Nacogdoches counties.
When should a homeowner act?
Act on any of the classic warning signs: mud tubes on the foundation, piles of discarded wings after a spring swarm, hollow-sounding or blistering wood, or frass pellets. Because Formosan colonies grow so large, early detection matters even more than it does with native species. If your home has never had a termite inspection — or your termite bond lapsed — schedule one now rather than waiting for evidence.
What goes wrong when people wait?
The most common failure mode we see is treating termites as a "call when I see them" problem. Subterranean termites eat wood from the inside out; by the time damage is visible, a colony has typically been feeding for months or years. The National Pest Management Association estimates termites cause about $5 billion in property damage every year in the U.S. — and homeowners insurance almost never covers it, because insurers classify termite damage as preventable.
How does Spot On protect homes from Formosan termites?
Our termite treatment program pairs a thorough inspection with targeted colony elimination, a termite colony elimination system for long-term prevention, and ongoing monitoring through our SPOTGuard + Termite plan. Spot On is a local, family-owned company serving Lufkin, Nacogdoches, Diboll and all of Deep East Texas.
What should you do next?
If you've seen possible termite signs — or simply don't know your home's termite status — request a quote and we'll schedule an inspection. If you're comparing coverage options first, read our guide to termite bonds vs. warranties.
Quick questions
How are Formosan termites different from native East Texas termites?
Formosan termites are also subterranean, but their colonies are dramatically larger — often millions of individuals — so they consume wood faster and can damage a structure in far less time than native species. They also build carton nests that can hold moisture, occasionally letting them survive above ground.
Does homeowners insurance cover Formosan termite damage?
Almost never. Insurers treat termite damage as preventable maintenance, which is exactly why active termite protection matters in East Texas.
What time of year do Formosan termites swarm in East Texas?
Formosan swarms typically happen on warm, humid evenings in late spring, often around dusk near lights. Discarded wings on window sills the next morning are a common tell.
