capshield plus canine 46-90

Skin Supplement for Extended Flea Protection. CapShield Maxx is a combination of Nitenpyram and Lufenuron. Lufenuron is a growth inhibitor (IGR) that will stay in the bloodstream for about 30 days. Any new fleas that get on the dog after the first day and take a blood feed will not fully reproduce. Capshield Maxx is the only way to introduce a long term IGR into the animal's environment as sun breaks down IGR in yard sprays within a day
