FRONTLINE Flea and Tick Spray is a trusted, veterinarian-recommended topical treatment designed to protect dogs and cats from fleas, ticks, and biting lice. Manufactured by Boehringer Ingelheim (formerly Merial), this spray contains Fipronil (0.25% w/v) , a powerful insecticide and acaricide from the phenylpyrazole family that works by blocking the GABA chloride channels in parasites, leading to their rapid death (VMD, 2026; Square Pharma, 2026).
FRONTLINE Spray is one of the few treatments that can be used on puppies and kittens from just 2 days of age, making it an incredibly versatile solution for pet owners (Frontline, 2026). This guide covers everything you need to know about FRONTLINE Spray—from its active ingredients and application method to its price in Bangladesh and real customer reviews.
What Is FRONTLINE Spray and How Does It Work?
FRONTLINE Spray is a topical ectoparasiticide formulated as a cutaneous spray solution for external use on dogs and cats (VMD, 2026). Its primary active ingredient is Fipronil (0.25% w/v) , which exhibits insecticidal and acaricidal activity against a broad spectrum of parasites (Square Pharma, 2026).
When applied correctly, Fipronil accumulates in the hair follicles and sebaceous glands of the skin, providing a reservoir of active ingredient that is released gradually over time. This creates a long-lasting protective layer that kills parasites on contact. The product is effective against:
-
Fleas (Ctenocephalides spp.)
-
Ticks (Rhipicephalus spp., Ixodes spp.) including paralysis ticks and brown dog ticks (Frontline Pet Care, 2026)
-
Biting lice (Trichodectes spp. and Felicola spp.) (Square Pharma, 2026)
-
Sarcoptes mange and Cheyletiella species (Square Pharma, 2026)
The spray is waterproof and remains effective even if your dog or cat swims or is bathed. Treatment with FRONTLINE Spray has been shown to significantly reduce the incidence of flea allergy dermatitis in both dogs and cats (HPRA, 2026).

How to Use FRONTLINE Spray Correctly
Proper application is essential for the product to work effectively. Follow these steps based on veterinary guidelines:
-
Prepare the Area and Yourself: Wear PVC or nitrile gloves to avoid skin contact (VMD, 2026). Work in a well-ventilated room or outdoors (Square Pharma, 2026).
-
Adjust the Nozzle: Ensure the pump nozzle is set to the spray setting.
-
Spray the Entire Coat: Hold the bottle upright at a distance of approximately 10–20 cm from the animal. Spray against the lay of the hair to ensure the product reaches the skin (Square Pharma, 2026). Make sure the entire coat is wetted down to the skin (Frontline, 2026).
-
Ruffle the Coat: Especially for longhaired animals, ruffle the coat to ensure the product penetrates down to the skin (Square Pharma, 2026).
-
Allow to Dry Naturally: Do not towel dry. Allow the coat to dry naturally in a well-ventilated area (Square Pharma, 2026). Keep treated animals away from fires or other sources of heat for at least 30 minutes following spraying and until the fur is totally dry (VMD, 2026).
-
Dosage: To wet the coat down to the skin, apply 3 to 6 ml per kg body weight (7.5 to 15 mg of active ingredient per kg body weight), which is equivalent to 2 to 4 pump applications per kg body weight (Square Pharma, 2026).
