Most are chewing pests that eat leaves and stems. The most common beetles that I battle in my garden are Japanese Beetles, Cucumber Beetles, Colorado Potato Beetles, and Mexican Bean Beetles. They chew the leaves to lace and destroy my plants and vegetables!
ALWAYS READ and FOLLOW the LABEL directions when using any pesticides.
Even natural or organic products can be deadly to pollinators like bees. If possible DO NOT spray when plants are in bloom. If this is not possible, spray early in the morning or later in the evening when bees are less active and ALWAYS read the label!
