Japanese Beetles

— Written By and last updated by

Well, we didn’t see many Japanese beetles last summer but we are certainly paying for it this summer. The Japanese beetles have arrived and are devouring everything they see. Wouldn’t it be great if they liked weeds? So here’s what you can do to save your gardens from being carried off:

  • When using pesticides, treat frequently. Beetles must ingest the insecticide
  • Reapply after heavy rain
  • Check plants often for infestations of Japanese beetles
  • When possible, pick beetles off into a bucket of soapy water
  • Consider treating the lawn for grubs

Remember that when Japanese beetles feed they emit a pheromone or scent that lets other beetles know that there’s food available so be diligent about spraying or picking off beetles because they will invite their friends!

Japanese beetle traps don’t work all that well, but if you do use them, make sure and follow the directions when placing the trap. When purchasing pesticides, look for products containing carbaryl, permethrin, acephate or neem.
