The Q&A Archives: japanese beetles

Question: what is the best way to get rid of them especcially on large bushes like crape myrtles.?

Answer: Many insecticides are labeled for use against adult Japanese beetles. Examples include pyrethroid products such as Tempo, Bayer Advanced Lawn & Garden Multi-Insect Killer, Ortho Bug-B-Gon Garden & Landscape Insect Killer, and Spectracide Bug Stop Multi-Purpose Insect Control Concentrate. Botanical alternatives include Neem products such as Azatrol or Neem-Away, or Pyola (pyrethrins in canola oil) provide about 3-4 days deterrence of Japanese beetle feeding. With all products, foliage and flowers should be thoroughly treated. The application may need to be repeated to prevent reinfestation during the adult flight period. Follow label directions and avoid spraying under windy conditions or when bees are foraging. Be sure the insecticide is registered for use on the plant or crop you intend to spray
