Amdro Quick Kill Outdoor Insect Killer Concentrate is not labeled for yellow jackets.  Talstar P would be a good alternative. It is labeled for use on yellow jackets and hornets. If you know where the nests are and can readily reach them, we would recommend using Wasp-X. This product can be used up to 15 feet away from the nest. This product will foam and cover the nest. It will provide a knockdown and fast kill of hornets and yellow jackets.
