Vectra 3D is a monthly topical treatment formulated to repel and kill fleas, ticks, mosquitoes, and other external parasites on dogs. Thanks to its easy-to-apply, quick-drying, fragrance-free, non-greasy, and waterproof solution, protecting your dog from pests doesn’t have to be a struggle anymore.
The fast-acting treatment repels and kills external parasites before they can attach to the dog’s body, meaning they don’t need to bite your dog to die. Limited flea feeding reduces the likelihood of health problems like anemia, irritation, flea allergies, dermatitis, and disease transmission.
By repelling and killing fleas, ticks, mosquitoes, and sand flies, Vectra 3D helps reduce exposure to parasites that may transmit certain vector-borne diseases like Lyme disease, Rocky Mountain spotted fever, babesiosis, ehrlichiosis, bartonellosis, hepatozoonosis, leishmaniasis, and heartworm disease. Keep your pet pest-free and healthy with the simple monthly year-round application of Vectra 3D Flea & Tick Topical!
Vectra 3D begins to stop fleas from biting in just 5 minutes. It is highly effective in killing fleas and ticks and kills fleas on dogs in 4 hours. It also knocks down ticks quickly after administration.
Formulated by Ceva Animal Health, Vectra 3D contains dinotefuran, pyriproxyfen, and permethrin as active ingredients. The triple-action formula works to kill fleas and ticks through contact and repels them to prevent them from attaching to your dog. Once the parasites land on your dog, they are exposed to the active ingredients, and the more they move across the coat or skin to find a spot to bite, the more they are exposed and affected.
Vectra 3D works on ticks by causing a “hot-foot” reaction. Ticks have sensors in their legs that are very sensitive to permethrin, making them run off the dog (hot foot effect). They are physically compelled to crawl back up the fur, away from the skin, without biting.
In fleas, Vectra 3D quickly interferes with the feeding behavior. Fleas begin to stop feeding within 5 minutes on the treated dogs and start falling off the dog without possible recovery.

Yes, Vectra 3D works against all stages of the flea lifecycle and ticks. It contains an insect growth regulator (IGR) that prevents the development of flea eggs and larvae.
Fleas can rise to the top of the dog’s coat as they die, which means if you can spot fleas after application, the treatment is working. If fleas persist, your pet may have picked up new ones from the environment. It can take up to 3 to 4 months of consistent use to eliminate fleas and their immature life stages completely.
No, Vectra 3D is not indicated for use on cats or other animals and may cause serious health consequences.
