The potato plants are very small and while checking around them, some Colorado Potato Beetles were found. These bugs overwinter as adults and each bug lays about 50 eggs on its host, potato plants. With a small patch of plants it is possible to pick them off and better still find the egg clusters before they hatch. Large patches must be sprayed. They cannot be ignored, since in a few days a potato patch vegetation will be completely destroyed. I have lived many places in Canada and have always had potato bugs in the garden.
