Nayflee Spray is a fast-acting ectoparasiticide spray formulated with Fipronil, designed for the treatment and prevention of fleas, ticks, lice and mites in dogs and cats. Fipronil is a phenylpyrazole insecticide that kills parasites by blocking GABA-gated chloride channels in their nervous system, causing hyperexcitation, paralysis and death within hours of contact. After application, Fipronil is absorbed into the coat and stored in the sebaceous glands of the skin, from which it is continuously released onto the coat surface over several weeks, providing residual protection beyond the day of treatment. Nayflee is supplied in a 100 ml pump spray bottle, from NUVO, a division of Intas Pharmaceuticals Ltd.
KEY FEATURES
- Contains Fipronil 0.25% w/v
- Kills ticks, fleas, lice and mites on contact
- Residual protection via sebaceous gland reservoir effect
- Spray format allows precise, full-body, bodyweight-based dosing
- 100 ml pump spray bottle
- Suitable for dogs and cats
BENEFITS
Fipronil works by blocking GABA-gated chloride channels in the nervous systems of ticks, fleas, lice and mites, leading to paralysis and death. Because it is stored in the sebaceous glands rather than absorbed systemically into the bloodstream, it remains concentrated on the skin and coat surface, where external parasites feed. This provides residual tick and flea control that continues beyond the day of application, and helps manage lice and surface-dwelling mites that can cause skin irritation and discomfort. The spray format allows precise, controlled dosing by bodyweight, which can be especially useful for very small dogs, puppies, kittens, and pets with dense or thick coats where spot-on distribution may be less even. Consistent, regular use may also help manage flea allergy dermatitis in sensitive pets by reducing flea exposure. Nayflee contains Fipronil only and does not include an Insect Growth Regulator (IGR); for flea lifecycle control including egg and larval stages, a separate IGR-containing product would be needed.

SAFETY INFORMATION
Age and pregnancy/lactation safety — please verify before publishing: The supplied marketing copy states this product is safe for puppies and kittens under 8 weeks of age, and safe for use in pregnant and lactating dogs and cats. These are specific, safety-critical claims that go beyond what's typical for many fipronil products, so please confirm this directly against the official product label/pack insert before publishing, since incorrect age or pregnancy safety information on a pesticide-class product carries real risk if wrong.
For external use only. Avoid contact with eyes.
