How many generations of carpenter bees emerge each year?

Carpenter bees typically have one generation per year. This means that they go through their entire life cycle—from egg to adult—in a single season. In the spring, the females emerge from their overwintering sites, mate, and begin the process of nesting and laying eggs. The larvae develop within the nests, pupate, and then emerge as adults by late summer. These adults often remain in the nests until the next spring, thus completing the cycle.

The nature of their life cycle limits them to one generation annually, as environmental conditions and food availability are generally more favorable for their development during this period. Understanding this single cycle is essential for effective pest control strategies aimed at managing carpenter bee populations.
