Tetramethrin can quickly knock down mosquitoes, flies and other flying insects and can repel cockroach well. It can drive out cockroach living in dark lift so as to increase the opportunity that cockroach contact insecticide, however, the lethal effect of this product is not so strong; therefore it is often mixed uses with Permethrin with strong lethal effect to aerosol, spray, which are especially suitable for insects prevention for family, public hygiene, food and warehouse. Normally it is used in combination with synergists (e.g. Piperonyl Butoxide), to increase effectiveness.
