Carpenter Bees, the Great Digger

You may give an attention to this fact, because it means that the female bees may sting you when they feel in danger, but not in groups. So there is possibility that you don’t notice any carpenter bee around you.

As we mentioned above, carpenter bees have high preference toward untreated woods and weathered softwood. They build a burrow tunnels inside wood to set up a nest. The tunnels are usually around 4 to 8 inches long, with ½ inch wide suit for their body. You can easily spot their nest by holes in the wood surfaces, mostly in untreated or unpainted woods [1]. They don’t like oil-painted or coated woods. But if you are not sure which of the holes on your wood furniture belong to the carpenter bees, spot their in and out route. Usually carpenter bees prefer hole with open downward position to the ground as their tough spot. The nest is used by the female carpenter bees to lay their eggs until hatch. Their hole is commonly very neat. They like to make a hole in the decks, siding, porches, doors, fences, wooden lawn furniture, and other wooden things around your living space. As a result? Carpenter bees may damage your garden furnishings and structural beams in your home.

Carpenter Bees’ Life Cycle

In middle of March, the female carpenter bees are laying eggs in the nest. After that the stage are: larval, pupal, and adult. It takes around 7 weeks from eggs to become adult bees [3]. When they become adult, it is not like they can fly and forage as they want. But they need to stay inside the wooden shelter for several weeks, and leave the nest during April or May. At that time they will be ready to do the job as pollinator and looking for food. Within a year, the female carpenter bees can reproduce 2 generations, mostly in US. But for areas less infested by carpenter bees, they only reproduce 1 generation within a year. Remember, the female carpenter bees have gone through intensive process during labor. It took a lot of time and energy. That’s why carpenter bees prefer to inhabit existing nest instead of excavate a new one. And this is also another reason to know the 10 tricks to keep carpenter bees away from your wooden furniture.
