Carpenter Bee
Xylocopa spp.
Carpenter bees are large, robust bees that drill perfectly round holes into wood for nesting. Unlike carpenter ants, they work alone or in small groups. Over time, repeated nesting in the same wood can cause cumulative structural damage to beams, door frames, and furniture.

Habitat & Behaviour
Activity & Breeding
Solitary nesters — each female drills her own tunnel into wood. Bores a perfectly round entry hole (about 10mm diameter), then turns 90° to create a gallery where eggs are laid in individual cells provisioned with pollen. Males are territorial but cannot sting.
Active Period
Year-round, active during daylight
