Where do carpenter bees hide during winter

 

Carpenter bees have to survive the winter. Before winter the old generation starts dying and the new generation leads their colony.

Usually, the carpenter bee colony is very small. Even a single female carpenter can start building a nest individually.

From the fall they start preparing for the winter. So, they move to a warmer location or in a safe location where they can protect themselves from cold. This is why carpenter bees are not seen often during winter.

It is also a fact to be considered that during winter carpenter bees choose warmer locations to live. It could be inside your house too. So, they can damage wooden materials inside your house. This is why you should try to get rid of them without killing them.

Almost all the season they spend in hibernation. They cluster together to keep themselves warm. Usually, the older generation dies before the winter emerges. The new generation starts preparing themselves for the next season.

They hide in a safe and warm location with enough food. Moreover, during winter flowers are scarce. Though bees can eat various things when there is no flower, they are less likely to go outside.

They have storage of food in their nest to survive the winter. So, they become inactive and spend the entire winter to keep themselves warm.

 

 

 

Can Carpenter Bees Survive Cold?

In most cases, carpenter bees become able to survive the cold. To survive the cold carpenter bees stop reproducing from the Fall. They have food storage for winter and they emerge to a safer location during fall. By doing so the new generation of the carpenter bee colony was able to survive the cold.

They keep themselves in their shelter to fight against the cold. They spend the entire winter inside their nest.

During spring, as soon as the temperature rises, carpenter bees start coming out from hibernation.

The female carpenter starts boring holes in wood cavities, tree cavities, or ground cavities. From the late spring to early summer the female carpenter starts laying eggs in the nest cavity. So, a new colony is produced and the new colony starts pollination and other activities.

As soon as the fall arrives this newly developed colony starts preparation for the winter. That is the new carpenter bee colony follows their ancestors.
