Hi-Yield Turf Ranger II is an insecticide that contains 2 different active ingredients, and could kill a bee that landed on a treated area. However, if you apply and water the product in when the bee activity is low, such as early morning or late evening, it should have less of an impact on those beneficial insects.
Hi - Yield Turf Ranger II should be applied, watered in as directed and completely dried before allowing pets in the treated areas. If used as directed, it is pet safe.
