Pheromone Traps

Pheromone traps are a good tool for monitoring insects easily attracted to pheromones (chemicals released by a insect species to exchange information). Insects are attracted to the scent (lure) at the apex of the trap, fall through the funnel, and remain in the container until collection.


Step 1. Assemble the pheromone trap by screwing the 4-inch-diameter (10-centimeter) bucket into the yellow, winged top.

Step 2. Attach either a pheromone capsule or a pheromone-soaked cotton swab to the top crux of the wings at the very top of the trap.

Step 3. Hang the trap by its handle on a metal post or nail. Be sure to replace the lure frequently, particularly when there is more than ½ inch (1.27 centimeters) of rainfall.

Note. Pheromone traps can attract a variety of insects. Only place pheromone traps during the time of the year you anticipate your target insect’s activity.
