Many insecticides are highly toxic to honey bees, bumble bees, and other pollinating insects. Certain materials should not be applied any time during bloom, while many others should be applied only in the early morning hours and/or late evening when pollinators are not foraging. Avoid spraying materials on ornamentals that are surrounded by blooming flowers or weeds. Simple steps like removing (mowing) blooming clover from lawns should always be practiced before applying materials that are harmful to bees. Select the least hazardous material (if given the choice) when plants in the infested area are in bloom. Always follow label directions for bee safety.
