Precor 2000 Plus Premise Spray uses the active ingredient (S)-methoprene to control fleas, ticks, ants, and other pests. It is an insect growth regulator (IGR) and an adulticide that will work against adult fleas and ticks for two weeks and kills flea eggs and prevents re-infestation for up to 7 months. This is the product that professionals use because of one-two punch of the IGR and the adulticide. This combination makes up the fast-acting formula that provides the knockdown power needed to rid your home of fleas and other pests. Precor 2000 Plus Premise Spray is versatile and reaches fleas hidden deep in many areas, including carpets, upholstery, and pet bedding. One can covers 2,000 square feet. If you need a bit more coverage or for your fleas spray to be labeled for a few more pests, you can try Precor’s sister product, Precor 2625!
