They most important part about using insecticide impregnated tags is that the whole herd is protected. The major challenge with shipping products made in Canada to a poorer country like Nepal is that it is just not affordable. The largest challenge with this product is that it is toxic to fish and bees. (Vetoquinol, 2000). This product cannot be disposed of near water as it waters soluble and will kill fish. (Vetoquinol, 2000) Another issue with this product is that it causes a huge decline in bees, which are already on the endangered species list. A deep concern is if this product was exported to Nepal it could cause more damage than good. There was also a study completed in the states it is rare for the horn fly to be prominent at elevations higher than 2400m, as well the face fly is not a problem at high altitudes either. (Scasta, 2015). Using high integrated pest management by increasing the altitude reduces input cost, and helps prevent the use parasite treatments. (Scasta, 2015)
