Vivaldis Vi-Fi Forte (Fipronil 0.25% w/v) Tick and Flea Control Spray for Dogs and Cats (100ml)

Ticks and fleas do not wait. And if you have both a dog and a cat at home, you want one product that works safely on both — without switching formulas, without guessing doses, without worrying about age or pregnancy.

Vivaldis Vi-Fi Forte spray is a Fipronil 0.25% w/v tick and flea control spray for dogs and cats that covers the whole household in one bottle. A single pump spray format that kills ticks, fleas, lice, and mites on contact, spreads through the coat via the sebaceous glands for lasting residual protection, and is confirmed safe for puppies and kittens from 8 weeks, pregnant pets, and lactating pets — a flexibility most Fipronil sprays in India do not explicitly offer.

Formulated without alcohol and free from harsh solvents, Vi-Fi Forte is gentler on skin and coat than many competing Fipronil sprays — a meaningful advantage for pets with sensitive skin or for households where the spray is used regularly. From Vivaldis Health & Foods Pvt. Ltd., Pune, the company behind the Bark Out Loud by Vivaldis range, manufactured by Disinfecto Chemical Industries Pvt. Ltd., Lucknow. Available in a 100ml pump bottle.

What Is Vivaldis Vi-Fi Forte Spray Used for in Dogs and Cats?

Here is what Vi-Fi Forte fipronil tick flea spray treats and prevents:

• Tick control — kills adult ticks on contact and provides residual protection that prevents reinfestation for weeks after application. Effective against all common tick species found on dogs and cats in India, including Rhipicephalus sanguineus, the brown dog tick is most prevalent during the monsoon season

• Flea control — kills adult fleas on contact and disrupts the flea lifecycle by preventing eggs and larvae from developing into adults, breaking the reinfestation cycle at the source rather than just treating the surface.

• Lice control — eliminates both sucking and biting lice that cause coat damage, skin irritation, and persistent scratching in dogs and cats.

• Mite control — provides coverage against surface-dwelling mites that cause skin inflammation and discomfort.

How Does Fipronil Work on Parasites?

• Vivaldi's Vi-Fi Forte spray uses Fipronil, a phenylpyrazole insecticide that works by blocking GABA-gated chloride channels in the nervous systems of parasites

• Blocking these channels causes uncontrolled nerve activity, leading to hyperexcitation, paralysis, and death of ticks, fleas, lice, and mites within hours of contact

• After application, Fipronil spreads across the coat and is stored in the sebaceous glands of the skin, from where it is continuously released onto the coat surface over several weeks — this is what gives Vi-Fi Forte its lasting residual protection beyond the day of application

• Because it is stored in the sebaceous glands rather than absorbed into the bloodstream, it is not systemic — it remains on the skin and coat surface where external parasites live and feed

• The alcohol-free, toxin-free formulation base means the active ingredient is delivered without the skin-stripping effects of solvent-heavy competing sprays

How Do You Apply Vi-Fi Forte Fipronil Spray Correctly?

1. Part the fur against the direction of hair growth so the spray reaches the skin

2. Hold the bottle 10 to 15cm from your pet's body and apply evenly across the entire coat

3. Dose at 6 to 12 pumps per kg of bodyweight — the higher end for pets with thick or dense coats

4. For the head and face, spray onto a gloved hand or cloth and apply carefully, avoiding the eyes, nose, and mouth

5. Allow to dry naturally — do not towel dry or rinse off

6. Keep your pet away from water and avoid bathing for at least 48 hours after application

Quick dosage guide:

 

⚠️ Before you use it:

• Apply in a well-ventilated area or outdoors

• Avoid the 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

• Keep other pets and children away from the treated coat until fully dry

What Are the Side Effects of Vi-Fi Forte Spray?

Side effects are uncommon when applied correctly. Here is what to watch for:

• Temporary skin irritation at the application site — mild redness or itching, particularly in pets with sensitive skin. Usually settles within a few hours.

• Drooling or excessive salivation — rare, occurs if a pet grooms the sprayed coat before it is fully dry. Prevent licking until the coat is completely dry.

• Lethargy or reduced appetite — very rare, typically resolves within 24 hours. Contact your vet if symptoms persist beyond this.

• Eye irritation — if the spray contacts the eyes accidentally, flush immediately with clean water and contact your vet if irritation continues

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

When Should You Not Use Vi-Fi Forte Spray?

Check with your vet before using if:

• Your pet is under 8 weeks of age

• Your pet is already on another ectoparasite treatment — combining without vet guidance can cause overexposure

• Your pet has open wounds or severely broken skin across large areas of the body

• Your pet has a known sensitivity to Fipronil or phenylpyrazole compounds

⚠️ Clinical Safety Notice:

• Vi-Fi Forte spray is confirmed safe for puppies and kittens from 8 weeks, pregnant dogs and cats, and lactating pets — always follow dosage instructions carefully

• Apply only in well-ventilated areas

• Prevent your pet from licking the coat until the spray has fully dried — licking before drying is the most common cause of adverse reactions.

• In multi-pet households, separate pets after application until all treated coats are completely dry

How Should You Store Vivaldis Vi-Fi Forte Spray?

• Store in a cool, dry place away from direct sunlight

• Keep the pump nozzle clean and tightly capped after every use

• Keep out of reach of children and pets

• Do not freeze or store near heat sources

• Check the packaging for the expiry date before use

What Are the Alternatives to Vivaldis Vi-Fi Forte Spray?

FAQs

What is Vivaldis Vi-Fi Forte spray used for in dogs and cats?

Vivaldis Vi-Fi Forte is a Fipronil 0.25% spray that kills and controls ticks, fleas, lice, and mites in dogs and cats. It provides residual protection for weeks after a single application by storing Fipronil in the sebaceous glands of the skin. It is safe for use on dogs, cats, puppies and kittens from 8 weeks, and pregnant and lactating pets.

How do you apply Vi-Fi Forte fipronil spray correctly?

Part the fur against the direction of growth so the spray reaches the skin. Apply at 6 to 12 pumps per kg of bodyweight across the entire coat. For the face, spray onto a gloved hand and apply carefully. Do not rinse off — allow to dry naturally. Keep your pet dry and avoid bathing for at least 48 hours after application.

Is Vi-Fi Forte spray safe for puppies, kittens, and pregnant pets?

Yes — Vivaldis Vi-Fi Forte is confirmed safe for puppies and kittens from 8 weeks of age, and for pregnant and lactating dogs and cats. Always follow the dosage instructions carefully and apply in a well-ventilated area. Prevent licking until the coat is fully dry. If you are unsure about the suitability for a very young or unwell pet, check with your vet first.

How often should I use Vivaldis Vi-Fi Forte spray on my dog or cat?

Vi-Fi Forte provides residual protection for up to 4 weeks after application, so monthly use is the standard recommendation for ongoing tick and flea prevention. During peak infestation periods — particularly India's monsoon months — your vet may advise more frequent application. Always follow your vet's guidance rather than applying more often than the label recommends.

What is the difference between Vi-Fi Forte spray and a spot-on treatment?

Both use Fipronil and work through the sebaceous glands for residual protection. The key difference is the application method and coverage control. A spray allows you to apply precisely across the entire coat, including hard-to-reach areas, and lets you adjust the dose by bodyweight with each application. A spot-on is applied in one or two spots and spreads on its own — quicker but less flexible for different coat types and sizes.
