Re: How can I prevent bee damage from drift of Entrust (spinosad)?
I haven't been in a situation with potential drift from insecticides. But, once the hives are screened, if you have water available at that location, set up a sprinkler so the water spray from the sprinkler encompasses the hive area (without getting water inside the hives). The water from the sprinkler should deal with possible insecticide drift.
