Fleas pass through a complete life cycle of four stages.
The flea population is typically made up of 50% eggs, 30% larvae, 15% pupae and only 5% biting adults. The completion of the cycle from egg to adult varies from two weeks to eight months. Normally the female flea lays between 15-20 eggs per day up to 600 in a lifetime. Eggs hatch in two days to two weeks into larvae found inside and outside. Sand, dirt and gravel are very suitable for flea development (sand fleas common name) Larvae take a week to several months to develop ready for the pupae stage digesting organic debris. Pupae takes five to fourteen days, adult fleas can emerge or remain resting waiting for a blood host. Adult fleas can hybernate up to one year with out a blood meal. In just thirty day, 10 female fleas under ideal conditions can multiply to over quarter million different life stages. Newly emerged adult fleas live only about one week if a blood meal s not obtained. Breaking the cycle is not just killing a few fleas you need to target all the stage cycles.
What could you do.
Only suitable to those of us who want to fix the problem, all or nothing.
Use a monthly treatment such as Frontline, Advantage, Revolution or other brand. Treat every animal in the house and treat them all year round. Inspect your dogs coat regularily for fleas and flea spores. Regular hydrobath for your dog every two weeks. Weekly cleaning of where your dog visits (wash their blankets). Monthly yard spray with Insect Growth Regulator such as Coopex EC from a produce store. Monthly house bombing, flea bombs can be purchases from the supermarket. Stay away from ofF LEASh AREAs read carefully.
Yard spraying and house bombing can go to every two months once you see a breakthrough. If you stay on top of them then do it every three months for ever.
Other wise I will be back "The Flea"
