  • Neem Oil: Spray the plants in the garden with neem oil as it helps to prevent adult beetles from feasting on them. Neem oil and potassium bicarbonate sprays are somewhat efficient, especially on roses. Neem oil has a substance that adult beetles consume and pass on to their eggs, which causes the subsequent larvae to perish before becoming adults. Reminder: Avoid using neem next to water sources like ponds, lakes, and rivers since it might harm aquatic life and fish. Once it rains, you must reapply it.
  • Row Covers: In the six to eight-week Japanese beetle feeding period, which starts in June, shield your plantings from the insects by using row covers. If your crops require pollination, make careful to remove the row coverings since they will keep out both pests and pollinators.
  • Use a dropcloth: Lay down a drop cloth. In the early hours of the morning because during this time the beetles are the most active, brush them off and pour them into a pail of warm water and detergent.
  • Insecticides: If you want to sprinkle or dust with pesticides, ask your local extension service or gardening center about the insecticides that are legal in your region.


If you have followed the aforementioned recommendations but still see Japanese beetles in the garden, yard, or other comparable locations, you most certainly have an infestation. You should get in touch with experts and allow them to take care of the issue for you to handle this situation effectively.
