Carpenter Bees Control
in Westminster.
Professional carpenter bees treatment across Westminster. Wood-boring bees that drill perfect 1/2-inch holes in eaves and decks.

Carpenter Bees are a recurring concern across the Denver metro, and Westminster is no exception. Westminster's terrain is rolling Front Range plain with major open-space holdings — Westminster Hills, Standley Lake, and the Big Dry Creek corridor. Wildlife pressure is significant, especially in neighborhoods backing to open space. Carpenter bees love unfinished cedar, redwood, fir, and pine — especially deck rails, eave fascia, fence posts, and outbuilding framing in sun-exposed locations.
Front Range homes with heavy cedar siding and unfinished deck construction experience persistent carpenter bee damage. Older fences, log structures, and pergolas are particularly vulnerable. In Westminster specifically, open-space adjacency in west westminster and along standley lake drives heavy rodent, vole, and wildlife pressure. apartment density along sheridan and federal corridors drives bed bug and roach calls. standley lake and big dry creek create persistent mosquito breeding habitat. compounds the picture — meaning Westminster homes face carpenter bees pressure that's distinct from the metro average.
EPC has run carpenter bees jobs across every corner of Westminster. Westminster housing is a mix of 1970s–90s tract single-family, mid-century neighborhoods on the eastern side, and new construction in West Westminster. Multi-family density along the corridor brings bed bug and cockroach calls; single-family homes face heavier rodent and wildlife pressure. Our approach is wood-boring bees that drill perfect 1/2-inch holes in eaves and decks.
How EPC Treats Carpenter Bees in Westminster
Direct Tunnel Treatment
Insecticidal dust applied directly into each tunnel. Kills the female, larvae, and any returning bees. Most effective in spring before egg laying.
Tunnel Sealing
After treatment, tunnels are plugged with wood putty or dowels and painted/sealed. Prevents reuse next season — carpenter bees prefer existing tunnels.
Preventive Wood Treatment
Borate-based treatment to vulnerable wood surfaces — eaves, deck framing, fence posts. Reduces susceptibility for several years.
Painting/Sealing Recommendations
Carpenter bees avoid painted and stained wood. Tech identifies which wood surfaces need attention to break the year-over-year cycle.
Signs of Carpenter Bees in Westminster Homes
- Perfect 1/2-inch round holes in deck rails, eaves, fascia, or fence posts
- Yellow-orange staining on wood below holes (bee waste)
- Coarse sawdust below holes
- Large bees hovering near or returning to holes (especially in spring and early summer)
- Year-over-year damage in the same wood pieces (returning bees and new generations)
Carpenter Bees Prevention for Westminster Properties
- Paint or stain all unfinished exterior wood — carpenter bees rarely tunnel sealed surfaces
- Replace severely damaged wood members; small damage can be filled and painted
- Inspect deck, eaves, and fence in early spring for new holes; treat immediately
- Use hardwoods or composite materials for new construction (less attractive to bees)
- Plug existing holes after treatment so they aren't reused
