Tick and Flea Control Spray for Dogs and Cats - TTK Big Boss Fipronil 0.25% | 100ml

Found a tick on your dog after a walk? Spotted fleas on your cat's coat? TTK Big Boss tick and flea control spray for dogs and cats kills ticks, fleas, and lice at all life stages, including eggs, larvae, and adults, in a single application, with no rinsing required.

Powered by Fipronil 0.25% w/v, a fast-acting ectoparasiticide trusted in veterinary parasite control across India, this spray dries quickly on the coat and continues to provide protection for up to 4 weeks after a single application. Unlike powders and shampoos that require rinsing or lengthy contact time, the spray format reaches the skin through the coat and is stored in the sebaceous glands, releasing slowly onto the coat surface over several weeks.

What sets this apart from most tick sprays is its safety profile, it is suitable for use on pregnant and lactating dogs and cats, and on puppies and kittens above 8 weeks, making it one of the most versatile Fipronil sprays for dogs and cats available in India.

(Available in 100ml. Marketed by TTK Healthcare Limited, Chennai. Manufactured by Makam Pharmachem, Bangalore.)

What Is It Used For?

Here's what TTK Big Boss Fipronil spray is used for:

• Tick control: Kills ticks on contact and provides up to 4 weeks of residual protection, making it effective for both clearing an active infestation and preventing reinfestation during peak tick season.

• Brown dog tick treatment: Specifically effective against Rhipicephalus sanguineus, the brown dog tick most commonly found on dogs in India, particularly during and after monsoon season.

• Flea treatment and prevention: Works as a flea spray for dogs and cats, killing adult fleas and targeting eggs and larvae to break the reinfestation cycle — suitable for both treatment and ongoing monthly prevention.

• Lice elimination: Kills body lice in dogs and cats, providing relief from the intense scratching, coat damage, and skin irritation that lice cause.

• All life stage coverage: Unlike treatments that only kill adult parasites, this Fipronil 0.25% spray targets ticks and fleas at all life stages, helping prevent reinfestation from eggs and larvae already in the environment.

• Safe use on young and pregnant pets: Suitable for puppies and kittens above 8 weeks, and safe for pregnant and lactating dogs and cats; one of the few sprays in this category that covers the entire household without restrictions.

How Does It Work?

• Fipronil belongs to the phenylpyrazole class of insecticides and works by blocking GABA-gated chloride channels in the nervous system of parasites, causing uncontrolled neural activity, paralysis, and death within hours of contact

• Because it acts on a receptor type not present in mammals, it is selective for insects and arachnids at the concentrations used in veterinary products

• After application, Fipronil is absorbed into the sebaceous glands of the skin and slowly released back onto the coat surface over time. This reservoir mechanism is what gives TTK Big Boss spray its residual protection for up to 4 weeks from a single use

• Because it kills parasites at all life stages, including eggs and larvae, it disrupts the reinfestation cycle rather than just eliminating the adults currently visible on your pet

How To Apply TTK Big Boss Fipronil Spray?

Bathe your pet the day before application and allow the coat to dry fully. Then:

• Part the fur against the direction of growth so the spray reaches the skin

• Apply at a rate of 3–6ml per kg body weight, using approximately 5–10 pump sprays per kg

• Spray across the entire coat, neck, back, belly, legs, and tail, without missing any areas

• For the face and head, spray onto a gloved hand and apply carefully, avoiding the eyes, nose, and mouth

• Allow to air dry naturally. Do not towel-dry or rinse off

• Keep your pet away from water and do not bathe for at least 48 hours after application

Repeat monthly for ongoing protection, or as directed by your vet.

⚠️ Before you use it:

• Not for puppies or kittens under 8 weeks of age

• Apply in a well-ventilated area or outdoors

• Avoid your pet's eyes, nose, and mouth during application

• Keep your pet away from open flames or heat sources until the spray has fully dried

• Wash your hands thoroughly after applying

What Are The Side Effects Of This Spray?

TTK Big Boss Fipronil spray side effects are uncommon when applied correctly. Here's what to watch for:

• Temporary skin irritation: Mild redness or itching at the application site, particularly in pets with sensitive skin. This usually settles within a few hours.

• Excessive drooling: Rare, but can occur if a pet grooms the sprayed coat before it has fully dried. Monitor your pet after application and prevent licking until the coat is dry.

• Lethargy or loss of appetite: Very rare, and usually resolves within 24 hours. If symptoms are prolonged, contact your vet.

• Eye irritation: If the spray contacts the eyes accidentally, flush immediately with clean water and contact your vet if irritation persists.

If your pet shows any serious neurological signs after application, including tremors, loss of coordination, or laboured breathin, stop use immediately and consult your vet.

FAQs

What is Fipronil spray used for? 

Fipronil spray is used to treat and prevent infestations of ticks, fleas, and lice in dogs and cats. It kills parasites at all life stages, including eggs, larvae, and adults, making it effective for both clearing an active infestation and preventing reinfestation. TTK Big Boss Fipronil spray is also safe for use on puppies and kittens above 8 weeks and on pregnant and lactating pets when used as directed.

How long does Fipronil spray last on dogs and cats? 

TTK Big Boss Fipronil spray provides protection for up to 4 weeks after a single application. Fipronil is stored in the sebaceous glands of the skin after application and slowly released onto the coat surface over time, giving it residual protection well beyond the day of use. Frequent bathing, swimming, or heavy rain can reduce the duration, monitor your pet and reapply as needed or as advised by your vet.

How quickly does Fipronil spray work? 

The TTK Big Boss starts acting within hours of the application. Most pet parents see ticks and fleas becoming inactive and falling off within 12 to 24 hours of the first spray, fleas typically die faster, often within a few hours. For a heavy infestation, a second application and simultaneous treatment of the environment may be needed to fully clear the problem. Reapply every month for continuous protection.
