Kitten bathed after flea treatment. Should I reapply Advantage?

Updated On September 23rd, 2025

I have a 7 week old kitten that has a lot of fleas. I bought kitten advantage and put it on her last night. I made the mistake of giving her a bath about 3-4 hours after it was applied. Should I reapply advantage?

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)
