Carpenter bees show up across Greater Houston every spring, drilling perfectly round holes into fascia boards, decks, fences, and eaves and returning to the same softwood year after year. Sasquatch Pest Control treats the galleries, protects your wood, and backs every stinging-insect service with a 100% guarantee and no long-term contracts.

How to Identify Carpenter Bees

Carpenter bees are large, robust bees about 3/4 to 1 inch long that look much like bumble bees, but their key difference is a shiny, hairless black abdomen rather than the fuzzy yellow-banded abdomen of a bumble bee. Along the Gulf Coast the Eastern carpenter bee is the common species; males often hover and dart aggressively near nest sites but cannot sting, while females can sting but rarely do. Instead of nesting in the ground, they bore into bare or weathered softwoods — cedar, cypress, pine, and redwood are favorites — leaving a clean, dime-sized entry hole on decks, pergolas, fascia, window trim, and fence rails.

Signs of a Carpenter Bee Problem

Look for smooth, round holes roughly half an inch across on the underside of eaves, deck rails, and unpainted trim, often with a fan of coarse sawdust (frass) and yellowish staining on the wood or ground below. In spring you may see one or more bees hovering and chasing near the same spot, and hear a faint chewing or buzzing inside the wood. Because females extend existing tunnels each year and woodpeckers tear into galleries hunting the larvae, an untreated Houston-area nest can cause widening structural damage and unsightly holes over several seasons.

How Sasquatch Treats Carpenter Bees in the Houston Area

Sasquatch starts by inspecting all the vulnerable softwood on your home — fascia, soffits, decks, railings, pergolas, and fences — to map every active gallery. We treat directly inside each hole with a residual dust that coats the tunnel so bees pick it up as they move through, eliminating adults and developing larvae, and we time the work to catch bees before new generations emerge. After the product has done its job we recommend sealing the holes so they cannot be reused, and we follow up to confirm the galleries are inactive. Every stinging-insect service is backed by our 100% guarantee, so if carpenter bees return between visits, we come back at no additional cost.

How to Prevent Carpenter Bees

Paint or apply a hard polyurethane finish to exposed softwood, since carpenter bees strongly prefer bare or weathered wood and usually avoid well-finished surfaces. Fill and seal existing holes with wood putty or a dowel once the gallery is treated, and consider replacing frequently attacked trim with hardwood or composite material. Store firewood and untreated lumber away from the house, keep an eye on south- and east-facing wood that warms early in spring, and address the first few holes quickly before females expand the tunnels and attract woodpeckers.

Frequently Asked Questions

Do carpenter bees actually sting?

Rarely. The males that hover and dart at you near a nest look intimidating but have no stinger at all. Females can sting but are docile and only do so if handled or seriously provoked. The bigger concern with carpenter bees in Houston is the structural wood damage they cause, not their sting.

How much damage can carpenter bees really do?

A single hole is minor, but the same females extend their tunnels every year and new generations start their own galleries in the same wood. Over several Gulf Coast seasons this weakens fascia, decks, and railings, and woodpeckers often make it worse by ripping open the wood to eat the larvae inside.

Why do carpenter bees keep coming back to the same wood?

They are drawn to bare, soft, sun-warmed wood, and they reuse and expand existing galleries season after season because it saves them the work of boring fresh tunnels. That is why simply swatting the bees does not solve it — the untreated tunnels remain attractive year after year.

Should I just plug the holes myself?

Not until the gallery is treated. If you seal a hole while bees or larvae are still active, they can simply chew a new exit and you trap developing bees inside the wood. We treat the tunnel first so the material reaches the whole gallery, then seal the holes so they cannot be reused.

How much does carpenter bee treatment cost in Houston?

It depends on how many galleries are active and how much vulnerable wood your home has, so a few holes in one deck rail is priced differently than widespread activity across fascia and a pergola. We inspect first and give you a free, upfront quote with no contracts, so you know the price before any work begins.
