Protection of Pollinators: Look for the “bee-box” or “bee hazard icon” on product labels and read the restricitions and instructions to protect bees and other insect pollinators. Bees and other pollinators will forage on plants when they flower, shed pollen, or produce nectar. Follow these steps when using products that are hazardous to bees: 1) minimize exposure of the product to bees and pollinators when they are foraging on pollinator attractive plants around the application site 2) Minimize drift of the product on to beehives or to off-site pollinator attractive habitat as drift into these areas will kill bees.
