Does Capstar flea medicine stop working after a couple of weeks, or should I be doing something else for my cat’s flea problem?

I gave my cat Capstar two weeks ago, but I’ve noticed he’s starting to scratch and bite at his fur again. I thought this medicine would keep the fleas at bay for longer. Does Capstar stop working after a couple of weeks, or should I follow up with another treatment? What should I be doing to help him stay flea-free?

Answer

It can be concerning to see your cat scratching and biting at its fur again after using Capstar. Capstar is effective at killing adult fleas quickly, but it doesn’t provide long-term protection.

  • Capstar kills adult fleas but does not prevent future infestations.
  • Additional flea control measures are recommended for ongoing protection.
  • Consider a follow-up treatment or a comprehensive flea prevention plan.

Capstar is designed to provide fast, temporary relief by killing adult fleas within 30 minutes of administration. However, it does not have residual effects, meaning it will not prevent your cat from getting fleas again in the future. For prolonged protection against fleas, consider using a monthly flea prevention product recommended by your veterinarian. It is important to also treat the environment by vacuuming regularly, washing your cat's bedding, and possibly using a household spray if recommended.
