CS 101 is an EPA registered, residual crack and crevice insecticide spray. CS 101 drops a broad spectrum of insects on contact. This cherry scented formulation contains esfenvalerate for residual control up to seven weeks and ETOC for quick knock down and flushing action. The dual action valve and spout allow the product to be sprayed in a powerful straight stream that can be directed into hard to reach areas or a less forceful mist pattern for use as a surface spray on baseboards, etc. Pleasant cherry fragrance.
