Read along as we let you in on the timeline of carpenter bee season, when they’re most common, when they go away and how long carpenter bees are active for.
When Are Carpenter Bees Active?

When Do Carpenter Bees Go Away?
Carpenter bees go away once the weather starts getting colder, generally around mid-September or October. When the weather starts getting colder carpenter bees are ready to cozy up in their nests and hibernate for the Winter until next Spring.
To determine when carpenter bees go away, take a look at their life cycle. But generally speaking, once fall comes around carpenter bees nests will be full and closed for the season.
Carpenter bees usually have a lifespan of 1 year and they are most active from early spring through to late summer. Every late summer, a new generation gets hatched.
Property owners must find and plug existing carpentry bees nests before their periods of hibernation runs out. Doing so saves you from stress and reduces the task of controlling the bees.
Where Do Carpenter Bees Go In Winter?

Do Carpenter Bees Hibernate?
Yes, carpenter bees hibernate during the Winter! Carpenter bees will return to their nests to hibernate and escape the cold weather, and wait for Spring to come!
How To Keep Carpenter Bee Activity Under Control:
There are several methods you can use to control these pests. But consider the two options discussed below:
- Painting of wood: The first method you should implement is painting or varnishing of your home’s exterior. Carpenter bees love untreated and unfinished wood, therefore they cannot build their dwelling when they encounter painted or varnished wood. By painting and adding varnish you can help to protect your wood from carpenter bee damage.
- Apply insecticides: If they have already made their tunnel in your home’s exterior, your next best bet would be to employ an insecticide against them. Sprays or dust come in highly recommended by professionals as they penetrate deep, reaching even into the interior areas of these tunnels. The pesticides need to get applied at dusk because that is the period when the bees are least active. The bees must also come in contact with the pesticide as they crawl through the entrance holes of their tunnels for the insecticides to have a higher effect.
These methods should help limit carpenter bee activity on your property and keep them away for good.
