I have to spray multiple times a year to control insects. Of course, I have a large garden, plus a lot of other host plants. The potato beetles are usually hardest to control, along with the squash bugs. I also have to spray beans, corn, tomatoes, and sometimes the strawberries. I use Sevin, Captain Jack's, Colorado Potato Beetle Beater, some organic stuff on occasion, and I have been known to use some off label chemicals made for use on agricultural crops.
