Japanese Beetle

Japanese Beetles

Japanese beetles are one of the top problems for roses besides black spot. Usually seen starting the end of June into July, these beetles unfortunately do not discriminate on what types of plants they feed on. Leaving behind skeletonized leaves and completely defoliated plants in their wake.

One beetle may not cause much damage, but they like to feed  in groups.

There is hope for your garden. Although it is impossible to get rid of Japanese beetles entirely, there are some controls which can be used that with a little time and patience will keep them in check.

What We Recommend:

Always apply chemicals in the early morning or late evening.  Only use chemicals as needed.

  • Hand Pick: Each morning pick them off plants and toss them into a bucket of soapy water. If you get the “scouts” that are the first to arrive, it will greatly reduce the overall population.
  • Bonide Neem Oil Is an excellent all purpose insecticide, miticide, fungicide for organic gardening. It is also safe to use around pets and children. Just follow directions on bottle. Will burn plants if applied during the heat of the day.
  • Garden Safe Crawling Insect Killer: Kills insects whom come into contact with it or ingest it within 24 hours. (Can not be used on vegetable gardens.)
  • St. Gabriel Milky Spore: Prevention is the best medicine. Place down Milky Spore to kill future grubs that turn into Japanese Beetles, following the directions on the back of the bag.
  • Rue: Is known to be a natural, herbal repellent for Japanese beetles. Plant it near your roses or raspberries.

We Do Not Recommend:

  • Japanese Beetle Traps: Many people ask about Japanese Beetle traps which are out on the market. We do not carry them here at the store, reason being is they attract more beetles to your garden than you may have had previously and they are not a very good means of eradication.
