Every spring and early summer, many homeowners begin noticing large bees hovering around decks, porch rails, fences, eaves, and wooden siding. These insects are often mistaken for bumble bees, but in many cases they are actually carpenter bees.
At Rockland Bee Removal, we regularly receive calls from property owners concerned about bees “hovering like helicopters” around their homes. Understanding carpenter bee behavior can help you identify the issue early and protect your wooden structures from long-term damage.
What Are Carpenter Bees?
Carpenter bees are large bees, usually about one inch long, with yellow and black coloring that resembles a bumble bee. However, one of the easiest ways to tell them apart is by their abdomen.
• Carpenter bees have a shiny, smooth abdomen
• Bumble bees have a fuzzy, hairy abdomen
As pollinators, carpenter bees feed on nectar and pollen from flowers. Unlike termites, they do not eat wood for nutrition.
Why Are They Hovering Around My House?
Carpenter bees are commonly seen hovering around:
• Porch rails
• Decks
• Wooden siding
• Eaves
• Fences
• Overhangs
• Fascia Boards
They are searching for nesting locations or guarding nesting territory. These bees bore perfectly round holes into wood where they create tunnels to lay eggs.
Because the holes are often located on the underside of wood or hidden in difficult-to-access areas, homeowners may notice bee activity without ever seeing the actual nest entrances
Are Carpenter Bees Dangerous?
Carpenter bees are generally not aggressive toward people. However, they can become a serious nuisance around homes and wooden structures.
Over time, repeated nesting can cause:
• Damage to decks, railings, and siding
• Wood weakening from tunneling
• Staining from bee droppings
• New holes appearing season after season
While a single season of activity may not create issues, years of repeated nesting can lead to noticeable deterioration of exterior wooden surfaces.
Why Carpenter Bee Treatments Can Be Difficult
Unlike many other insects, carpenter bee treatments work best when the actual nesting holes can be located and treated directly.
In some situations, the holes are very high up, hidden or inaccessible inside trim/fascia boards, soffits, siding, or under decks. When this happens, only general area treatments may be possible, which are often less effective than direct nest treatments.
Carpenter bees are also persistent insects. Even after treatment, they may continue living nearby and create new nests in untreated wood. Because of this behavior, carpenter bee treatments are difficult to guarantee.
When Professional Help Is Possible
At Rockland Bee Removal, carpenter bee treatments are most effective when the actual nesting holes in the wood can be located and treated directly.
In many situations, the holes may be hidden underneath decks, inside trim boards, behind siding, or in other inaccessible areas. When nesting holes cannot be found, treatment options become much more limited and results may vary.
Because carpenter bees often continue living in the area and may create new nests over time, we cannot guarantee carpenter bee treatments.
If the nesting holes cannot be located, hanging carpenter bee traps around the affected area may be one of the only practical options to help reduce activity. While traps will not eliminate all carpenter bees, they can sometimes help lower the number of bees around decks, porches, eaves, and other wooden structures.
If you are seeing carpenter bees around your home, take photos of both the bees and the areas where activity is occurring so the species and possible nesting locations can be identified. ◆
