Is there an insecticide spray sold in Canada that kills Japanese Beetles?
Not interested in in killing larva in the lawn or Japanese Beetle traps.
Thank you for contacting the Toronto Master Gardeners about controlling Japanese beetles.
In Ontario, for home gardeners, there are no registered pesticide products to control this pest, or the available products are very expensive, according to this Government of Ontario website. You may also read another TMG reply HERE
We recommend the non-chemical option of physical removal of these beetles.
In the early morning or in the late evening when the beetles are not as likely to fly around, simply knock them into a small container of water with a few drops of soap added where they drown. Begin this process at the end of June or the beginning of July and continue until sometime in early August.
I hope you find this information helpful! Good luck!
