Best used for: Flea control once a month after infestations have been eliminated. Kills hatching fleas only. Dose: 500mg per capsule Flea Control also known as Lufenuron ( Also known as Program ) is stored in the animal's body fat and transferred to adult fleas through the host's blood when they feed. Adult fleas transfer it to their growing eggs through their blood, and to hatched larvae feeding on her excrement. It does not kill adult fleas. Lufenuron, inhibits the production of chitin insects. Without chitin, a larval flea will never develop a hard outer shell (exoskeleton). With its inner organs exposed to air, the insect dies from dehydration soon after hatching or molting (shedding its old, smaller shell). It has no toxic effects at any dosage on humans other mammals or any animals not having hard shells.
