When Your Home is Attacked By Carpenter Bees

 Carpenter Bee Control

Carpenter Bees resemble bumblebees in appearance and size. These bees build their nests in trees or frame buildings. If you see a swarm of bees near the eaves of a home or wood drilling, it’s likely carpenter bees. Specifically, carpenter bees do not eat wood. Instead, they excavate the tunnels to rear their young and for shelter.

Typically, carpenter bees attack unpainted items, such as roof eaves, railings, windowsills and doors. These bees drill a small round hole into the wood and then bores tunnels. Over time, there may be considerable structure damage. If your home has been attacked by carpenter bees, it’s time to implement some bee control.

If you want to eliminate carpenter bees without using an insecticide, try plugging the holes with putty or caulk. While you might think that the bees would burrow their way out, but carpenter bees don’t try to get out of trapped areas.

Blocking up those entrances to the carpenter bee galleries usually works. But after you apply the putty or caulk, be sure to paint over it. You can also try to agitate the colony and vacuum them out. Just keep in mind that this strategy is only effective with new colonies.

With a home infestation of carpenter bees, there are bee dustings, sprays and liquids to get rid of these pesky creatures. Apply the dust in as many carpenter bee holes as possible. Although the holes look only an inch deep, it usually is set at a 90 degree angle. You can purchase dusters with a curved tip to reach the bees including the eggs.

Delta dust is a great residual dust that works well on the exterior and heavy moisture areas, it can be found at www.epestsolutions.com.

With residual liquid treatments to spray, spray the areas where the carpenter bees are boring in the wood. Be sure to check the underside of wood surfaces, including window frames, fascia boards, overhangs, soffits, fence posts, decks and siding. It’s best to use these products during the spring season at intervals of three to four weeks. If the structure is log or cedar, more than two treatments may be needed. After applying the spray, use a bee dust at all entry points. After the bees are killed, plug up the entrances with a caulking compound.

Prevention is key to carpenter bee control. Varnish or paint wood surfaces to make them less attractive. Since carpenter bees scout the area for exterior openings, seal and caulk any cracks, crevices or openings. Keep in mind that carpenter bees will reuse holes from the previous season. These holes should be caulked before the fall season. The best time for extermination is spring as nesting and the rearing of young generally occur in late spring or early summer. The female carpenter bee bores a main corridor in the wood and lays eggs in galleries. She brings in pollen for the hatched larvae to feed on and seals each gallery for protection during development. Continue treatment until the fall for the best results.
