What Is The Purpose Of Carpenter Bees – Even though we love them with all our hearts, the truth is that each of our dearest friends and family members has a side that drives us crazy at times… and that doesn’t make us love them any less. I think our relationship with pollinators and other beneficial insects is like the one we have with our loved ones: pollinators pollinate and play an important role in native plant reproduction and food production… and sometimes can become a nuisance if not managed properly. As for our loved ones, the fact that pollinators can become a nuisance should not stop us from supporting them; We must learn how to maintain our relationship while controlling its negative aspects. In today’s post we will talk about a pollinator in particular, with which our relationship can sometimes become complicated. Let’s talk about carpenter bees.
. If you enjoy being outdoors, I’m sure you’ve already seen them. The most common species in our area is the Eastern carpenter bee, which is about the size of a bumblebee, has a “spot” on its back and dark wings, and when exposed to sunlight, has a shiny abdomen. These bees are very common in our area and are very common flower visitors to many ornamental and food producing plants.

The Eastern Carpenter Bee: An Unloved Nectar Robbing Bee
Because they are similar to bumblebees, carpenter bees are often confused with them. To tell them apart, a quick look at their abdomen can tell who’s who; Carpenter bees have shiny abdomens, while bumblebees have very fuzzy and hairy abdomens.
It is no coincidence that carpenter bees are called that. Their life cycle is closely tied to wood, in which females dig holes to build their nests. Carpenter bees have impressive mandibles that they use to chew soft wood to dig galleries. Although they may look impressive, these are peaceful bees that only sting when physically and aggressively disturbed. In the spring, the males of these bees establish and defend their territories, a strategy that wins females a mate. During this defense, they “drive away” other males but also “drive away” people who are close to what they perceive to be their spaces. However, these males are harmless because they lack stingers and thus cannot sting.
The life cycle of these bees is seasonal. In early spring, hibernating adults emerge, mate, and females build their nests in the wood. These nests consist of galleries, at the end of which females lay eggs and store food (nectar and pollen) for the developing larvae. Larvae develop throughout the spring and summer and emerge as adults by late summer. These adults are typically carpenter bees that fly in early fall. Once the weather begins to turn cold, in early winter, these adults return to some cavities and overwinter there, emerging the following spring to restart the cycle.
As we saw above, carpenter bees nest in wood. If a house or any structure is made of wood, they may choose it to build their nests. When this happens, these bees have the potential to affect the integrity of our wooden buildings. So, while these bees are very important pollinators of our region, we see that this particular aspect can be problematic in our relationship with them. The good news is that there are solutions!

The best solution is actually not reactive, but proactive. If we have important wooden structures that we don’t want these bees to invade, it’s best to use hardwood (which these bees don’t like) and/or treat the wood first. Treatment involves painting or varnishing the wood, which prevents adults from nesting in it. A good treatment is to coat the wood with almond oil in the spring, which prevents bees from choosing the nest.
Another proactive step that can be taken along with wood staining is to distract bees from the wood we want to protect. To do this, one can use pieces of wood that one is not interested in keeping and display them in other parts of the open area so that females choose to nest in those surfaces rather than in the wood that we want to protect. In addition to protecting the wood, it also allows us to support these important native pollinators in our region, while minimizing potential negative impacts on our buildings.
If carpenter bees are already established, there are several options. First, if the number of nests is really small, and the structure can be removed and replaced, then this should be done and the new wood structure stained to protect it. If possible, the removed piece of wood can be placed elsewhere in the green spaces around the property, which provides nesting resources for these pollinators and simultaneously protects the home and supports native pollinators.
How To Deal With Carpenter Bees
Carpenter bees can sometimes build several nests in building materials. If it affects the integrity of the building, more drastic measures are required. Photo: JoeyZ51.
If the piece of wood cannot be removed and, in particular, if the nests appear to compromise the integrity of the building, more drastic action should be taken. In that case, the use of pesticides can be considered. If this route is taken, it is important not to carry out pesticide applications without proper knowledge, which means it should be done by an expert applicator. This point is really important, because non-targeted and incorrect insecticide treatments may lead to low efficacy of the treatment on carpenter bees and the death of other non-target beneficial insects (eg, other bees, beneficial pest control insects, etc. .) that may be associated with the treated area.

The ‘buzz’ Is True Carpenter Bees Are Important Pollinators
Pollination is a buzzword right now and a lot has been said about pollination and pollinators. But how do people learn about pollination and pollinators? How do people know who pollinators are and how pollination works? As I am researching pollination, I would like to take this opportunity to share with you…
The golden leaves of the trees outside my window remind me that the growing season is almost over and winter is coming. However, those same golden colors also remind me that spring is not far away, and in my place, it starts with some gold in my garden. This golden…

Identifying Carpenter Bees
Contrary to popular belief, most wild bees lead solitary lives. But among these solitary creatures, the carpenter bee stands out. These tiny bees raise their brood just like human mothers.
Maternal care has tremendous benefits for the microbiome, development, and overall health of young carpenter bees. It protects bees from harmful pathogens during critical stages of development.
In fact, the lack of maternal care results in an alarming increase in pathogen loads. The researchers found that 85 percent of these pathogens were fungi, while 8 percent were bacteria.
Such an imbalance severely affects the bees’ microbiome, which is vital to their health. This not only affects their immune system and gene expression but also leads to developmental changes in their brain, eyes and behavior.

A prominent fungus, Aspergillus, induces the deadly stonebrood disease in bees, turning them into mummy versions of themselves.
