Q&A - How do I get rid of Japanese beetles?
Question:
What is the best way to kill/get rid of Japanese beetles? I have dusted with Sevin dust but they have returned and multiplied. They are everywhere.
Answer:
Japanese beetles are an invasive species with few natural predators in our area. These beetles spend most of their lives as grubs underground. The adults give off a pheromone which attracts more beetles to the area. For this reason Japanese beetle traps do not work. They attract with the pheromone but they attract more beetles than they trap. If you pick them off and put them in soapy water they will die and the pheromone won’t linger to attract more. They can be killed by insecticides but more will arrive after the insecticide has worn off in a few days.
