My outdoor cat has fleas after Advantage. Is it safe to reapply?

Since it's been two weeks since you late applied the Advantage, you can try another dose of it. He can also have Capstar again. Be sure to disinfect your home, as that will be a continuing source of fleas. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Best of luck, I hope this helps!

Hi and thank you for your question on Petco Pet Education Center, formerly Petcoach! Advantage II is not safe to use twice in 48 hours. The product safety specifications indicate that it should not be applied more often than once every 7 days for cats. I would not want to overload her system with more topical product in case she received a full dose and all of the dose was absorbed. In a week, it would be okay to apply another application. Hope this has helped!

If it's been at least two weeks since you applied the Sergeant's, which it has been, it's safe to apply the Advantage now. You will also have to disinfect the environment. Wash their bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.

If you haven't treated the house, that will be a continuing source of fleas. I would call an exterminator to kill the fleas. As for Chubbs, give him Capstar once a day for the next seven days. It's safe to give one pill daily, and starts killing fleas in 30 minutes. When it has been two weeks since you last applied the Advantage, you can apply another dose. I hope this helps!

I would check the instructions on the package of the product you applied for instructions but most say not to bathe within 24 hours of application. I would be worried about overdosing as she would have absorbed most of the chemical already but some may have washed off. I would wait to retreat and see if there are any live fleas in a few days. You can continue treating with grooming with a flea comb and treated baths until the package says you can retreat (usually a month later)

Thanks for using Petco Pet Education Center, formerly Petcoach! Yes, you may in about 5-6 days. However, I would highly recommend you use a stronger and likely more efficacious product. There are plenty of flea products in the market and a lot of them are very effective. I prefer Bravecto and Frontline plus. You can pick one of those products. The nice thing about Bravecto is that it is very effective and it is only applied once every 3 months. You can also use a product called Capstar along with one of the previously mentioned products which can help kill a lot of fleas at once. Remember to vacuum all the surfaces that have contact with your pup regularly. This is very likely going to work well. Good luck and have a great day!

I would not use the Advantage so close to applying another treatment. Wait at least 3 weeks since previous treatment. It may still be killing the fleas on the cat, but if fleas are still in the environment, new ones are jumping onto the cats. I would recommend treating the environment to help get rid of fleas more effectively. It will take at least 4 months to get rid of fleas if you are treating ONLY the pets. Make sure all pets are treated as well. Here are some articles for more info. http://www.veterinarypartner.com/Content.plx?P=A
