How many days until fleas die after a Barse treatment? - briefly
Fleas generally perish within two to three days following a Barse application. The product’s active ingredients act rapidly, eliminating the infestation in that timeframe.
How many days until fleas die after a Barse treatment? - in detail
Fleas begin to die within 24 hours of exposure to Barse, and most adult insects are eliminated by the second day. The product’s active ingredient attacks the nervous system of the parasite, causing rapid paralysis and death after contact.
The life‑cycle disruption proceeds as follows:
- Adult fleas: 90 % mortality within the first 48 hours; the remaining survivors are usually killed by the second application.
- Eggs: Barse does not affect eggs directly, but the rapid loss of the adult population prevents further egg laying. Any eggs already present hatch in 2–3 days.
- Larvae: Without a fresh supply of adult blood meals, larvae fail to develop and die within 5–7 days.
- Pupae: The protective cocoon can shield developing fleas for up to two weeks; however, the lack of new adults entering the environment limits the emergence of viable adults.
Because the residual activity of Barse persists on treated surfaces and on the host’s coat for approximately 30 days, a second dose is recommended after 7–10 days to intercept any newly emerged adults that escaped the initial kill. This schedule ensures that the entire flea population, including those hidden in the pupal stage, is eradicated.
Key points to remember:
- Initial adult kill: 24–48 hours post‑application.
- Egg hatch: 2–3 days; no new eggs are laid after adult death.
- Larval death: 5–7 days due to lack of nourishment.
- Pupae may emerge up to 14 days; a follow‑up treatment at day 7–10 prevents reinfestation.
- Residual protection lasts about one month, supporting long‑term control.
The overall timeline from the first treatment to complete eradication of the existing flea population typically spans 10–14 days, with continued protection for the remainder of the month.
