Nyguard EZ1 is an insect growth regulator with pyriproxyfen, that cuts the reproductive cycle of fleas, roaches, ants, and flies. Pyriproxyfen not only breaks the life cycle of these insects, but prevents re-infestation by interfering with their growth process. The active ingredient, Pyriproxyfen can be found in both NyGuard EZ1 and NyGuard IGR, but with different formulas. Both of these formulations of NyGuard are photostable in sunlight and can be used outdoors in yards to control fleas.
Happy with the purchaseArrived promptly and as described. I've used it as one part of a flea decimation plan, and one week after starting I'm already seeing significantly less fleas. Thank you.
