Easy to mount this trap where you need it and easy to remove the jar for discarding bees. Only catches carpenter/wood boring bees with attractant (pre-treated wood, never requires more).
Wood-boring bees can nest in a wide range of softwoods and hardwoods, especially if weathered. Eastern species prefer soft woods (cedar, redwood, pine, fir).
Carpenter Bees will attack structural timbers, firewood and lawn furniture. Look in the bare wood near eaves and gables, ceilings of porches, weathered wood in decks, siding, shutters, and you might see evidence of nests.
