Damage of Carpenter Bees

It’s that time year when the birds and the bees start their hunt for flowers to nibble at and spread the pollen so nicely as a part of their ecosystem. These creatures are such an important part of our global ecosystem that we need to safeguard them so to keep it healthy and thriving. Unfortunately, sometimes bees, such as the carpenter bee, can become a problem for homeowners. The damage that carpenter bees can cause can be widespread and continue year after year if treatment is not provided.


Carpenter bees make their nests in wood, which may mean an old tree stump, logs, or wooded areas around your home. It may also mean that these bees could target your home. Specifically they tend to target wood that is untreated, such decks, porches, outbuildings, sheds, outside steps, fences, and other external structures.


When carpenter bees make a nest in the wood around your home, they prefer to tunnel upwards into wood. These tunnels go up a couple inches and then take a turn to follow the grain of the wood. This is usually horizontal to the ground. Each tunnel is only a foot or two in length and the carpenter bees don’t actually eat the wood. Rather, they tunnel it out so as to have nesting space. If you have multiple carpenter bees or those that make return visit year after year, there can be significant damage made by the holes – about the size of a nickel – and the hollowed-out tunnels. Here are some of the damage that can occur.


  • Wooden steps and railings can lose their integrity if the carpenter bees tunnel multiple times in the same area. After significant damage, the steps and railing can snap.
  • Support beams around decks and sheds can begin to warp and “give” if the bees target an area around the beam.
  • If the bees tunnel around windows or door frames, these can also bend and potentially break.


Look for small holes in your wood about the size of a nickel and for bees that resemble bumble bees around your home. If you suspect that you may have carpenter bees, call us for treatment.

Identifying Carpenter Bees and the Damage they Cause

Carpenter bees are masters of disguise. Carpenter bees are large, black bees that closely resemble bumble bees. In fact, many homeowners believe that they are bumblebees and don’t give them a second thought until they discover damage on the exterior of their home. That is when they realize that the bumble bee was, in fact, a carpenter bee in disguise. Don’t be fooled. Here are some suggestions on identifying carpenter bees and their damage so you can call Pest-End Exterminators and solve your sneaky bee problem.

  • Appearance – To correctly identify a carpenter bee versus a bumble bee, look for a bee with a black shiny body, with white, orange or yellow hairs on the thorax. In addition Carpenter bees are about 3/4 inch to 1 inch (1.9 to 2.54 cm) in length. Females have black heads, and males have white markings on their heads. And finally look for dark, thick hair on the legs. Carpenter bees and bumble bees tend to hover and bounce around, so don’t expect to take out a ruler to measure but rather get a general idea about the physical features.
  • Behavior – These pests tend to seek out wood whether it is in the form of a tree, shed or the exterior of your home. They are searching for a nesting area and will often hover around a nesting area during the day. Male carpenter bees will hover outside the nesting area to protect the female as she works.
  • Damage – If you suspect that the bumble bees in your yard are not bumble bees but rather carpenter bees do a thorough inspection of your home especially under eaves and around decks where there is wood to be found. Look for bees boring holes into wood or flying near holes in trees. The carpenter bees will excavate the wood with a perfectly round hole at the opening. This hole indicates damage to your wood area whether it is the shed, facade, eaves or directly into your wood siding.

Wood Boring Bees – The Damage of Carpenter Bees

Over the past growing season did you notice bees that hovering around your eaves or notice small, round holes along the outside of your home? While you may believe these bees to be bumblebees, you may be misidentifying what could be a carpenter bee instead. Carpenter bees resemble bumblebees in both size and appearance, but are not social insects but do have the ability to bore hole into the exterior of your home.

Difference Between Carpenter Bees and Bumblebees

Carpenter bees are large, colorful wood-boring bees that look somewhat like bumble bees. The difference is that bumble bees are uniformly covered with dense hairs whereas carpenter bees have the upper surface of the abdomen bare and shiny black. Bumble bees have a hairy abdomen with at least some yellow markings. Bumble bees usually nest in the ground whereas carpenter bees tunnel into wood to lay their eggs. Bare, unpainted or weathered softwoods are preferred, especially redwood, cedar, cypress and pine.

The Damage of Carpenter Bees

Carpenter Bees like many other bugs overwinter in wood within abandoned nest tunnels. Female carpenter bees, once fertilized, excavate tunnels in wood and lay their eggs within a series of small cells. You may notice entrance holes and tunnels are perfectly round and about the diameter of your finger. They may be seen around the exterior of your home especially under eaves. Coarse sawdust the color of fresh cut wood will often be present beneath the entry hole, and burrowing sounds may be heard from within the wood. Carpenter bees tend to reuse old holes from one year to the next. The extent of damage to wood which has been utilized for nesting year after year may be considerable.


Pest-End Exterminators can evaluate the area and determine of your home has carpenter bees that have been tunneling deeper and deeper every year. We can treat and remove carpenter bees so that your property will be free of these wood borers.


The Interesting World of Bugs

Almost everywhere on the planet there are bugs. These critters are wildly diverse in color, size and behavior. While most homeowners call us to eliminate the pests from their property, we can’t help but marvel in their interesting features and characteristics. Every once and a while it is fun to take a closer look at pests and their interesting world.


Did you know. . . ?

  • A cockroach can live for up to 3 weeks without its head!
  • The weight of all the termites in the world outweigh the weight of all humans 10 to 1!
  • The queen of a certain termite species can lay 40,000 eggs per day.
  • The life cycle of a mosquito features four stages: egg, larva, pupa and adult.
  • Female mosquitoes drink blood in order to obtain nutrients needed to produce eggs.
  • A mosquito flaps its wings 500 times a second.
  • Male mosquitoes do not bite humans but rather live on plant juices and other natural liquids from plants and decomposing organic material.
  • The average housefly lives for one month.
  • Out of every 1,000 Mosquitoes, one female carries a disease that could be fatal to humans.
  • Houseflies find sugar with their feet, which are 10 million times more sensitive than human tongues.
  • To survive the cold of winter months, many insects replace their body water with a chemical called glycerol, which acts as an “antifreeze” against the temperatures.
  • Ants leave trails and communicate with each other using pheromones as chemical signals.
  • There are nearly as many species of ants (8,800) as there are species of birds (9,000) in the world.
  • Although insects can be found by the buckets just about anywhere on Earth, there’s one continent where they barely have a foothold: Antarctica. In fact, only one true species of insect, a wingless midge called Belgica antarctica, calls the southernmost continent home.


Carpenter Bees and the Damage they Cause

Many people tell us that they seem to have a large number of bumblebees every spring and summer. This may be the case, but these “so-called” bumblebees may, in fact, be something a bit more damaging – the carpenter bee. If you notice these imitators flying around the eaves of your home you may be dealing with carpenter bees.

Carpenter Bees vs Bumblebees

Carpenter bees resemble bumblebees in both size and appearance, but are not social insects. They construct their nests in trees or in frame buildings. Bumblebees are, in contrast,  large social bees 1/2 to 1 inch long, with black and yellow or, rarely, black and orange body markings. Their nests are underground and they spend most of their time traveling between the nest and the flowers from which they obtain food. Most of the top of the abdomen of carpenter bees is without hairs and is shiny black in color while the abdomen of a bumblebee is fully clothed with hairs, many of them yellow in color.

To determine if you have carpenter bees or bumblebees, look for bees that have a large, shiny, solid black abdomen. The male carpenter bees may dive bomb your head with a whitish spot on their face. The males do not have stingers. The female carpenter bees uses sharp teeth to excavate a perfectly round tunnel in soft wood. You may notice a half-inch or so diameter hole or holes that have been drilled in wood for their nests.

Damage Potential

While one carpenter bee may seem fairly harmless, it is usually the subsequent brood that will expand and grow the damage to wood of your home. According to Homeowner Today carpenter bees prefer to excavate their nests in soft, unpainted wood – such as the back side of fascia boards, siding, window trim, and porch ceilings. They also bore into decks, outdoor furniture, fence posts, and swing sets. Softer woods – like pine, cedar, redwood, and cypress – are more attractive for nests while treated lumber and hardwoods are less inviting.


While you can not see into these tunnels to examine just how extensive the damage is, Pest-End can do a thorough evaluation and discuss treatment options before your carpenter bee problem becomes a structural problem for your home.

Carpenter bees

Spring and summer are such wonderful times to enjoy the outdoors, especially if you have been working hard to nurture your lawn and garden.  Nothing can ruin that feeling more than finding unwanted pests damaging your lawn, garden or worse, your home.  This weeks blog we will be discussing one such pest – the carpenter bee,  including:  identification, behavior and treatment.

For most of us, bees are just a nuisance to be avoided,  but for individuals who suffer from severe allergic reactions to bee stings, having these pests in the yard is much more than a nuisance, it can be a real danger.

Identification – Carpenter bees, along with bumble bees,  are  the largest native bees in the United States. There are numerous species of carpenter bees that inhabit a broad range of ecosystems from tropical to subtropical to temperate. Carpenter bees are very often mistaken for bumble bees in that they resemble bumblebees.  They are rather large and mostly black but carpenter bees don’t have the yellow markings. They may show aggressive behaviors by darting or hovering around you.  Male carpenter bees will not sting you but a female one can pack a punch!

Behavior – Carpenter bees get their name from the main behavior they partake in – boring holes in wood  to make nests to lay their eggs.  They create galleries to lay their eggs in almost any wood they can find but especially like door and window frames, eaves, under decks and wooden outdoor furniture.  You can actually hear them inside the wood.  It is most likely the chewing of the wood that you are hearing.  You will possibly notice a completely round half inch hole for the entrance to the gallery. Carpenter bees, if allowed to dig their tunnels year after year, can do some real damage to your home.

Treatment – Given that most of the damage is inside the wooden structure and homeowners have no idea how extensive it may be, it is a good idea to contact an experienced pest management company like Pest-End with years of experience eliminating these types of pests.  Pest-End will be able to identify and chemically treat the area to eliminate the problem.
