Break the flea reproductive cycle, clear tick burdens on contact, and prevent vector-transmitted diseases with Intas Nayflee Plus Spot-On for Dogs, available online at PetMitra. For companion dogs across India, ticks and fleas represent a persistent year-round hazard that peaks during hot summer and humid monsoon months. Ticks transmit life-threatening hemoprotozoan pathogens—such as Babesia canis, Ehrlichia canis, and Hepatozoon—while fleas cause severe pruritus, flea bite hypersensitivity, and Flea Allergy Dermatitis (FAD). A common frustration among pet parents is that ticks and fleas reappear within days of bathing or using standard adulticide sprays. This occurs because adult fleas represent only 5% of the total flea population—the remaining 95% exist in the home environment as microscopic eggs, larvae, and pupae. Treating only the adult fleas leaves the domestic reservoir intact. Intas Nayflee Plus provides complete eradication through a synergistic Dual-Action Chemical Matrix: Targeted Neuro-Inhibitory Adult Knockdown (Fipronil 9.8% w/v): A broad-spectrum phenylpyrazole insecticide and acaricide. Fipronil selectively binds to arthropod neuronal gamma-aminobutyric acid (GABA)-gated and glutamate-gated chloride channels. By blocking the inhibitory flow of chloride ions, it triggers uncontrollable neural hyperexcitation, paralysis, and death of adult fleas, ticks, and biting lice within 24 to 48 hours of contact—without requiring parasites to take a blood meal. Complete Life-Cycle Interruption ((S)-Methoprene 8.8% w/v): An advanced Insect Growth Regulator (IGR) that mimics natural juvenile hormone in insects. Absorbed directly by developing eggs and molting larvae, (S)-methoprene disrupts chitin synthesis and blocks larval pupation into adult fleas. Female fleas that come into contact with the treated dog produce sterile, non-viable eggs, stopping new flea generations from establishing in furniture, rugs, and bedding. Sebaceous Gland Reservoir Effect: Following topical application between the shoulder blades, the carrier vehicle disperses the active molecules across the dog’s epidermal lipid layer within 24 hours. The formulation concentrates inside hair follicles and cutaneous sebaceous glands, continuously replenishing onto the hair coat for 30 full days. Waterproof & Bath-Resistant: Once fully absorbed and bound to the cutaneous lipid layer (48 hours post-application), the formulation remains effective despite routine bathing, swimming, or outdoor rain. Easy, Stress-Free Application: Applied directly onto the skin at the base of the neck, eliminating the struggle of force-feeding oral pills or the mess of whole-body chemical dips.
