Injuries caused by the German yellow jacket Vespula germanica F. to dry and lactating dairy cows (Bas tourus) in 5 herds in Israel were monitored and adversely affected ≤ 65% of the cows. Elimination of large alternative protein sources (placentas, sewage containing milk from the milking parlor), and prebaiting with high-quality minced meat (01' fish) in adequate numbers of baiting cages around the dairy farm for several days, are necessary for successful control. Significant control was achieved after a shorter period of time when the dairy farm was surrounded by a smaller area of uncultivated land than by a larger area. At some dairy farms there were significant differences among numbers of wasps visiting the various cage sites and significant variability between baiting days. Efficient and significant control was achieved by minced meat bait containing 1.5% acephate (orthene) and 2% micro encapsulated diazinon (Antikan). Wasps were totally repelled by minced meat bait containing 2.25% of a plant-derived bioinsecticide derived from Meliaceae (Ag100).The potential of using Ag 1000 for repelling yellow jackets from teats and udders of dairy cows is discussed.
