Life Cycle of the Flea

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 pet and subsequently lay eggs, which drop off your pet’s coat. Within days, larvae hatch from the eggs and live undetected in your pet’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 pet to continue the life cycle. When these new fleas are seen on your pet, treat with Capstar Tablets.



Capstar Tablets should be administered according to the following schedule. Weigh your pet prior to administration to ensure proper dosage. Do not administer to pets under 2 pounds.
