Talstar P is labeled to be used for treating underground nests for Bees, Wasps, Hornets, and Yellow-Jackets. The product label suggests mixing 1 fl oz per gallon of water and applying in late evening when insects are at rest. Aim spray at nest openings in ground, bushes and in cracks and crevices which may harbor nests, saturating nest openings and contacting as many insects as possible.
