Japanese beetles aka June bugs. Nasty things. You can do it the old fashioned way and spend untold hours by picking them by hand and throwing them into a bucket of water, hoping you got them all, as recommended by a Canadian gardner or you can use "just another insecticide" named spinosad. Spinosad is available under numerous brand names. Any company that supplies gardening products will have it. The names change but as long as the active ingredient is spinosad it is all the same thing. For decades organic gardeners have wanted a safe insecticide and now we have one. This "just another insectcide" as described by our Canadian gardener is totally organic and safe for humans and pets up to the hour of harvest... It is an all around pesticide as it will also take care of caterpillars too. It also works very well on ants, both on the plant and underground. So, if you want to spend hours searching for bugs and caterpillars on your vegetables and spraying with hit or miss soaps or pepper sprays that only work on soft bodied insects forget spinosad. On the other hand if you want an inexpensive means of quickly controlling all of your garden pests you now know how to do it.
