Driftwatch (also known as Beecheck) is a tool that is used to help protect honey bees from exposure to chemicals that are toxic to bees.  By adding the locations of your beehives to the map and registry, pesticides applicators will avoid application of pesticides toxic to bees to blooming crops in close proximity of the registered location during heavy honey bee foraging hours. Pesticides labeled as toxic to bees may not be applied to blooming crops by commercial applicators between the hours of 8AM and 6PM in areas within a one mile distance from a registered apiary location, according to the “Pesticide/Bee Rule” of the Iowa Administrative Code Chapter 21-45.31(206).
