Why is using an insect growth regulator (IGR), like the Nylar® in Bio Spot Stripe-On Flea Control, so important?
Flea infestations often start from the few fleas that the family cat picks up and brings back home from his wanderings in the neighborhood. Treating such cats with Bio Spot Stripe-On Flea Control for Cats and Ferrets prevents any fleas that they pick up from infesting your house. Cats will normally groom off (kill) the few adult fleas within days, and the Nylar in Bio Spot prevents any eggs those fleas may lay from developing into biting, breeding adults.
