Effipro Duo Spot-on solution for cats and dogs, offers optimal protection against ticks and fleas and from household flea infestations. Effipro Duo’s unique combination of pyriproxyfen, an insect growth regulator, with fipronil, an adulticide, kills adult fleas and ticks without requiring a blood meal, sterilises adult fleas and inhibits the immature life stages to offer three months of protection against flea life cycle completion. It is sold as single pipettes and in packs of 24 pipettes. Each pipette features Effipro's patented drop-lock system to aid application.

If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.
