Mantis 1×2 Flylight Glue Boards are sold individually, or by the package. Each package contains six full-sized glue boards measuring 16.5”× 9”. Glue boards are black in colour to hide dead insects from view. Contains Reflectobakt sleeve to protect from the drying effect of the UV light. Special hard glue stays on the board, not your hands. Boards are double-coated, front and back, to protect against moisture absorption in steamy or high temperature environments.
