Куда деваются блохи после обработки кошки? - briefly
After a cat is treated, fleas either die on the animal or fall off and die in the environment, often within a few hours as the insecticide takes effect. Residual spray on the cat’s fur also kills any remaining fleas that later try to re‑infest.
Куда деваются блохи после обработки кошки? - in detail
When a cat receives a flea treatment—whether a topical solution, oral medication, or a spray—the adult insects on the animal’s coat are killed almost immediately. The dead bodies, often referred to as flea debris, fall to the floor, carpet, or bedding and become part of the household dust. Over the next several days, these remnants are removed by routine cleaning: vacuuming, sweeping, or washing of fabrics.
The surviving stages of the flea life cycle behave differently:
- Eggs: Most products prevent adult fleas from reproducing, so few eggs are laid after treatment. Any eggs already present are laid on the cat’s fur, then drop onto the environment. They hatch within 2‑5 days, producing larvae that seek dark, humid areas such as cracks in flooring, under furniture, or in pet bedding.
- Larvae: After hatching, larvae feed on organic debris, including adult flea feces (often called “flea dirt”) and dead bodies. They remain hidden in the same micro‑habitats where eggs fell. Continued use of the treatment reduces the adult population, eventually depriving larvae of food, causing them to die or fail to develop.
- Pupae: Larvae spin cocoons and become pupae, a dormant stage that can persist for weeks or months. Pupae are resistant to most adult‑targeting products; they await favorable conditions, such as vibrations or increased temperature, to emerge as adults. As the treated cat remains flea‑free, emerging adults have no host and eventually perish.
Effective control therefore relies on two complementary actions:
- Kill the adults on the animal – immediate reduction of biting insects and interruption of egg laying.
- Eliminate environmental stages – regular vacuuming, washing of bedding at 60 °C, and use of environmental insecticides or growth regulators to destroy larvae and pupae.
If the household is thoroughly cleaned and the cat continues to receive monthly treatments, the flea population collapses within 4‑6 weeks, and the insects that initially fell off the pet are removed through routine housekeeping.
