Safer’s Japanese Beetle Trap is an easy-to-use and effective method to control Japanese Beetles in your garden. Uses patented Biolure controlled-release pheromone system to lure insects into the trap and disrupt the mating cycle. The floral lure attracts the females while the pheromone lure brings in the males. Recycle the dead beetles in your compost pile. Replace the lures after 4-6 weeks, bags as needed. Use at least one trap per 20 metres along two sides of the area you are trying to protect.
