Carpenter Bee Control in Cibolo, TX
In Cibolo, carpenter bees usually announce themselves with a neat, round hole about the width of a pencil eraser in fascia, a fence rail or a deck board, a little pile of sawdust under it, and a big shiny black bee hovering nearby. Have the active holes treated and plugged, then paint or seal the bare wood so the next generation looks elsewhere. Call or text (210) 281-1064, or book online, to schedule an inspection.
Bee damage, or something else? The sawdust test #
AgriLife's carpenter bee bulletin says the entrance hole is close to perfectly round and about 1/2 inch across, and that no other insect makes an opening that large and that round (AgriLife L-1826). Fresh sawdust usually piles up below an active hole.
The bee is 3/4 to 1 inch long, glossy blue-black, sometimes with a green or purple sheen. Its abdomen is shiny and nearly bare on top. A fuzzy abdomen means a bumble bee, which nests in the ground or old debris, not in wood; see bumble bees in Cibolo.
Which wood on a Cibolo house is at risk? #
| Spot | Why it draws bees | First fix |
|---|---|---|
| Back side of fascia and eave trim | Often left unpainted, sheltered and sunny | Paint all faces of the board |
| Fence posts and rails | Weathered softwood | Paint or replace worn boards |
| Deck rails and pergolas | Exposed grain, overhead cover | Seal with paint or polyurethane |
| Siding, shed trim, play forts | Weathered, bright spots | Inspect each spring |
Carpenter bees favor redwood, cypress, cedar and pine, and they move on to hardwood once weather or decay has softened it. AgriLife says holes are usually in well-lit spots with some overhead protection.
Homes from Cibolo's 2000s boom #
Cibolo built a large share of its houses in a single decade. Census survey data for 2020 to 2024 shows 36.9% of the city's homes were built between 2000 and 2009 (Census ACS). Many of those fences, decks and trim boards have now had close to two decades of Texas sun and rain, and the Texas Apiary Inspection Service names weathered siding, fence posts, decks and eaves as prime targets.
If your house dates from those years, the paint on hidden faces may be thin or gone. That is often where the first holes appear.
Old fence posts and outbuildings on former farm ground #
The San Antonio River Authority's Cibolo Creek plan describes farmland in the area being converted into residential subdivisions (SARA master plan). Where a property still has an older fence line, a barn or a wooden shed from those days, check it closely. Bare, aged posts are just the kind of wood the bees like.
Do they sting? #
Males are the ones that dart at your face around the deck, and males cannot sting. Females can, but AgriLife says they do so only when handled or provoked. A nesting female can get testy if you start working on her hole, so take care during repairs.
Fixes that hold #
- Paint beats stain. AgriLife rates oil-based or polyurethane paint and pressure-treated wood as the most effective; well-kept latex paint usually works. Sources disagree on stain, and AgriLife considers it inadequate.
- Never plug an untreated hole. New adults will chew back out.
- Metal flashing or screen is a last resort for boards that keep getting hit.
- Want to keep some bees? AgriLife suggests a softwood nesting block in the garden, away from the house.
How Pest Trappers treats carpenter bees in Cibolo #
The technician looks over trim, fences, decks and outbuildings, counts active holes, and checks whether any boards are weakened. You hear the options, and each gallery is treated with a labeled product before plugging. Sources differ on the wait before plugging, from 12 hours to a day (AgriLife) to a few days (Kentucky and Florida extension). Badly damaged wood should be replaced. AgriLife also notes that termites, carpenter ants and wood-boring beetles sometimes turn up during these inspections, so we look for those too. The price is set after the inspection. Pest Trappers LLC (TPCL #0887549) is a family-owned company with a Texas Department of Agriculture license, and the office will confirm your appointment.
