Cheristin kills fleas. Its active ingredient, spinetoram, starts killing fleas in just 30 minutes and remains effective for up to 6 weeks to keep your cat protected from fleas, although monthly application is recommended.
Not at all. Cheristin kills adult fleas in 30 minutes after contact. If you see fleas on your cat, they are most likely new adult fleas that will die very quickly.
If there are any fleas in your cat's environment, it can take weeks or even months for flea larvae to emerge and grow into adults. Cheristin kills adult fleas before they can lay eggs, breaking the flea lifecycle.
All cats in the household should be treated with an approved flea protection product to minimize the likelihood of flea re-infestation. It may also be necessary to apply an approved flea treatment product to your carpet and furniture in an attempt to remove the presence of fleas in your cat's environment. Low volume dosage is one-size-fits-all for cats or kittens 8 weeks of age and older that weigh 1.8 pounds or greater.
Maintain consistent monthly application of Cheristin to provide continual flea protection for your cat and prevent future infestations.
Cheristin is a quick-drying, topical solution that isn't greasy or messy. It has a rounded applicator that makes it easy to apply and comfortable for your cat.Cheristin is only for cats and kittens eight weeks of age or older and weighing 1.8 pounds or more. Always read, understand and follow the label and use directions.
HOW TO APPLY:
1. Remove one applicator tube from its packaging.
2. Hold the applicator tube in an upright position.
3. Press the cap down and listen for a "click" that indicates the tube has been punctured.
4. Hold upright and remove the cap. Check to be sure there is an opening at the tip of the tube.
5. Part the hair on your cat's neck at the base of the head until skin is visible. Place the open tip of the tube directly above the skin and squeeze the tube 2-4 times to expel the contents directly on the skin.
6. Discard the empty applicator tube in the trash.
We recommend applying Cheristin monthly. For best results, apply at the base of the head—not between the shoulder blades—to minimize the chances of your cat licking the product. Avoid getting the product in your cat's eyes or mouth.
