The following practices will help to reduce dangers to honey bees when using insecticides against Japanese beetles and other insect pests. Use insecticides only when needed and at the recommended rates. If possible, select an insecticide that is least hazardous to bees. Of those in Table 1, methoxychlor is the least harmful. Use the least hazardous method of application.
Sprays drift less than dusts and are less likely to kill bees in nearby areas.
Once dry, spray deposits are less harmful than dust formulations. Do not treat when honey bees are active on the crop. Applications in the late afternoon are least likely to damage bees. Avoid treating blooming plants. The use of some products may not be legal in your state or country.
