Japanese beetle traps are a great way to prevent these pests from growing larger. Traps work by luring males away, and killing them before they can mate.
There are different types of traps to buy, but the main idea is that traps contain some sort of attractant such as pheromones (chemical messengers) to attract males into the trap. They are then killed by poison or when the trap has a mechanism to prevent them from leaving.
