The carpenter bee trap for the yard is safe and effective. Eliminate pesky carpenter bees in just four steps 1. Grasp the wasp trap and extract the net from it. 2. Peel off the release paper to expose the adhesive. 3. Position one end of the outer net beneath the lid until it clicks into the snap. Continue to install the remaining frames in sequence. 4. Pass the rope through the loop atop the lid, allowing the trap to dangle near the insect nest. Reminder: Before replacing the sticky paper, please check whether all the wasps on the sticky paper are dead.
