How do Barс flea drops work for cats? - briefly
The product is absorbed through the cat’s skin, circulates in the bloodstream to the sebaceous glands, and releases fipronil, which interferes with the flea’s nervous system, causing swift death. One monthly application sustains protective concentrations, preventing new infestations.
How do Barс flea drops work for cats? - in detail
Barc flea drops are a topical solution designed for felines. The formulation contains a neurotoxic insecticide (commonly fipronil or imidacloprid) combined with a carrier that facilitates skin absorption. When applied, the active ingredient penetrates the stratum corneum, enters the bloodstream, and is redistributed through the cat’s sebaceous glands to the skin surface, where it remains active for weeks.
Application procedure:
- Measure the dose according to the animal’s weight, as indicated on the product label.
- Part the fur at the base of the skull, away from the eyes and mouth.
- Squeeze the calibrated pipette onto the skin, allowing the liquid to spread naturally.
- Avoid bathing or swimming for at least 48 hours to ensure complete absorption.
Mechanism of action:
- The insecticide binds to the γ‑aminobutyric acid (GABA) receptors in the flea’s nervous system.
- Binding disrupts inhibitory neurotransmission, causing rapid hyperexcitation, paralysis, and death.
- Systemic distribution reaches fleas that bite the host, ensuring that adult parasites are eliminated within 12 hours of contact.
- Residual activity interferes with egg development and larval maturation, breaking the life cycle.
Efficacy timeline:
- Initial kill of adult fleas occurs within 12–24 hours.
- Prevention of egg hatch and larval emergence continues for up to 30 days, providing month‑long protection.
- Re‑application is required at the end of the efficacy period or when the cat’s weight changes significantly.
Safety profile:
- Formulated exclusively for cats; canine‑specific products may contain ingredients toxic to felines.
- Toxicity is low when used as directed; accidental ingestion can cause vomiting or tremors.
- Contact with eyes, mucous membranes, or open wounds must be avoided.
- Wash hands after handling, and keep the product out of reach of children and other pets.
Overall, Barc flea drops function by delivering a systemic insecticide that rapidly eradicates adult fleas, inhibits reproductive stages, and maintains protective levels on the cat’s skin for a full month when applied correctly.
