Most traps are designed to catch carpenter bees and also capture other flying stinging insects commonly labeled as wasps (including paper/red wasps) and mud daubers; some product descriptions refer more generally to trapping flying insects.
Many traps use visual attractants—colored, multi-dimensional patterns (often called VisiLure or similar)—that draw bees toward a sticky surface or trap entrance where they become caught.
Traps typically lure insects visually and then capture them either on a sticky surface where they expire or inside a contained vault or removable jar for removal. Some models advertise chemical-free, odorless operation and touch-free disposal mechanisms.
Most traps are intended to hang or be mounted near man-made structures where bees bore holes—common locations include eaves, awnings, pergolas, garages, and sheds. Some models include mounting hardware, while others can be set or hung with the provided parts.
Product descriptions commonly state these traps work best from spring through fall, targeting both queens and workers during that period.
