The Damage They Cause

Carpenter bees bore into wood to create nests, which can lead to significant structural damage over time. Unlike termites, they do not consume wood but excavate tunnels for their larvae.

Common Affected Areas

• Siding and Eaves: These are prime spots for nesting, often going unnoticed until damage becomes extensive.
• Decks and Fences: Wooden outdoor structures are attractive to carpenter bees seeking shelter and breeding grounds.
• Windows and Doors: Frames and trims provide easy access for these bees to enter and nest.

Statistics show that a single carpenter bee can create up to 1 inch of tunnels in a wooden surface annually, leading to weakened structures and costly repairs.

Life Cycle and Behavior

Understanding the lifecycle of carpenter bees is essential for effective management. Their lifecycle consists of four stages: egg, larva, pupa, and adult.

Lifecycle Stages

1. Egg: Laid in the tunnels created in wood, the egg hatches within a few weeks.
2. Larva: The larva feeds on stored pollen and nectar, growing rapidly.
3. Pupa: The larva enters the pupal stage, developing into an adult bee.
4. Adult: Emerging from the tunnel, adult bees continue the cycle by creating new nests.

Carpenter bees are solitary by nature, unlike their social counterparts, which means each female operates independently. This solitary behavior can complicate control efforts, as infestations may spread unnoticed.

Prevention and Control Methods

Preventing carpenter bee infestations involves making your property less attractive to these wood-boring insects. Here are some effective strategies:
