Solutions for Japanese Beetles

  • Japanese Beetles

Be prepared!  The Japanese Beetle has been spotted in in the Midwest.

Japanese Beetles are not picky about what they eat and can cause a great deal of damage in a short period of time.  They chew on almost 300 different varieties of plants.  Some favorites include asparagus, fruit trees, raspberries, grapes, maple trees, birch trees and roses, but will also feast on many other varieties of plants, trees and shrubs.

Controlling Japanese Beetles

Japanese Beetle Traps are very effective but can draw a lot of beetles in, be ready with plenty of replacement bags.

Earl May’s Eight is a very efficient spray that is labeled for the use on a wide range of plants.  It is available in ready-to-use sizes as well as concentrates.

    Does the eight spray keep them away or just kill on contact or both ?

      Hi John,
      Thank you for your question. Super Eight Insect Control will kill Japanese Beetles on contact and also prevent them from feeding on your plants. Remember to reapply after a rain and always follow label directions.
      Grow your own way,
      Earl May

      The beetle traps and Earl May Eight are both great ways to treat a full grown tree invaded by the Japanese Beetles.

    This did not answer my question about products to use for my large linden trees which have Japanese beetles on them. I had read someplace that there are systemic products available. I know imidacloprid would kill bees, etc, and I thought there were other systemics available that were not as long lived in the tree that would be better to use for blooming trees that could be applied after the tree was finished blooming. Do you know the name of these products, and do you sell them?

      Thanks for the question Jane. We are not aware of a systemic that is labeled for use on linden trees for Japanese beetles. We verified this with information recently published by the Horticultural Department at Iowa State University.

      Traps may be an option but they do run the risk of attracting more beetles into the area. However, we do know of homeowners that have been successful using several traps around the tree to protect the defoliation on their linden.
