Fleas can be a problem because they reproduce so rapidly. A single female flea may produce up to 2,000 eggs over her lifetime. Eggs hatch and can develop into adults within only three weeks. Adult female fleas feed by ingesting blood from your cat and subsequently lay eggs which drop off your cat's coat. Within days, larvae hatch from the eggs and live undetected in your cat's surroundings such as the carpet, bedding, and other protected areas. Flea larvae spin a cocoon, and when appropriately stimulated, a young adult flea emerges and jumps onto your cat to continue the life cycle. After biting a PROGRAM-treated cat, the female flea ingests lufenuron which is deposited in her eggs. Lufenuron prevents these eggs from hatching or developing into mature adults. This safe and convenient approach to flea control effectively breaks the flea's life cycle and controls flea populations.
