Carpenter Bee Control for Avon Porches, Barns, Decks and Log Siding

How do I tell a carpenter bee from a bumble bee?

Look at the top of the abdomen. Carpenter bees have a shiny, mostly hairless black abdomen, while bumble bees are fuzzy with yellow bands all the way back. Carpenter bees hover around eaves and porch rails and nest in wood; bumble bees nest in the ground, in old rodent burrows or under decks and sheds.

The difference decides who you call. Carpenter bees in wood are a job for a pest technician. Honey bees clustered on a branch or living inside a wall should go to a local beekeeper, since honeybee removal is not offered here. Paper wasps under the eaves and ground-nesting yellowjackets are covered by wasp and hornet nest removal.

Do carpenter bees sting?

Male carpenter bees, the ones that hover and zoom at you near the porch, cannot sting at all. Females can, but rarely do unless handled or pinned against skin. The bigger concerns are the slow damage to wood and, for anyone allergic to bee stings, the chance of a sting while working on a ladder near nests.

Males have a pale yellowish patch on the face; females have an all-black face. You do not need to tell them apart to book a visit, but it is reassuring to know that the bee following the kids across the deck is all bluff.

Why do carpenter bees go after barns, porches and log homes?

Carpenter bees prefer bare or weathered softwood with a sheltered underside, which describes most barn siding, porch ceilings, exposed rafter tails, fascia boards and log walls. Painted or solid-stained wood is far less attractive. Old holes are reused year after year, so a barn that has had bees for a decade can hold dozens of tunnels.

Older farm properties around Avon's French Creek District still have original barns and outbuildings, many of them unpainted. Farther south, horse farms in Columbia Station and Grafton add stalls, run-in sheds and board fences. Log-sided homes and cabins in rural Lorain County are especially exposed, since every log end and chinked joint is an invitation.

When should carpenter bees be treated in Avon?

Treat in spring, as soon as you see bees hovering and fresh sawdust below a hole, usually April into May around Avon. That is when females dig and stock the tunnels, so treating then stops the year's brood. A late-summer visit catches newly emerged adults, and holes should be sealed afterward, ideally before the next spring.

Lake Erie keeps the shoreline cooler in spring, so bees in Avon Lake or Sheffield Lake may get going a little later than those inland.

Winter is the wrong time for dust, since the galleries sit quiet under lake-effect snow and cold, but it is a fine time to plan repairs, sand and paint, or replace boards riddled with holes.

Will sealing the holes stop carpenter bees?

Sealing helps, but only after treatment. Plugging an active gallery can trap bees that then chew a new exit, and untreated larvae may emerge right through the plug. Once a gallery is treated and quiet, a wood dowel set in exterior glue, followed by paint or solid stain, makes that spot far less attractive next spring.

Paint and solid stain are the strongest long-term defense on fascia and porch ceilings; clear sealers and semi-transparent stains help less. Some owners replace the worst boards with composite trim or aluminum-wrapped fascia, which carpenter bees generally leave alone.
