This product provides 7-way control to kill:

• Fleas
• Ticks
• Chewing lice
• Mosquitoes
• Flea larvae
• Flea eggs
• Prevents the development of flea pupae

This product combines three active ingredients:

Fipronil attacks flea and ticks’ nervous systems – paralyzing and ultimately killing them
Cyphenothrin is a synthetic pyrethroid-like substance that attacks flea and ticks’ nervous systems-paralyzing and killing them
(S)-methoprene is an insect growth regulator (IGR) that prevents flea eggs and larvae from maturing to adults

This combination plays a crucial role in existing infestations, because:

Only 5% of active flea infestation in your home or on your pet are adult fleas.

The other 95% of the fleas are in the immature flea life stages: eggs, larvae, and pupae. They are almost invisible to the naked eye.

This product is topical only and is dispersed over your dog’s body by the natural oils on their skin and attaches to the hair follicle. This process can take up to 24 hours.

The product should begin to kill fleas and ticks within 5 minutes.

This will kill fleas on the pet, but not those that are in the bedding, carpets, or yard. It will also kill flea eggs and larvae on the pet, thus preventing them from multiplying there. Fleas only spend 20% of their life on the host animal, so proper cleaning and treating of the pet’s environment (bedding, carpets, kennel, yard) is necessary. We recommend that you replace or treat your pet’s bedding and treat your carpets and yard with products that will kill fleas in those areas.
