| Japanese beetles are a difficult pest to control. Your best bet is a two-prong approach: one to deal with the larvae, one to deal with the adults. Japanese beetle grubs are best controlled by spraying beneficial nematodes on the lawn and garden area. These microscopic worm-like creatures attack only the grubs in the soil and not plants, animals or humans. Spray them in spring when the temperatures are above 55F. You can also try a new product called whole neem oil. This is different than standard Bioneem in that it is a stronger concentration of this organic spray. Persistence is the key to control. Best wishes with your garden! |
