I got rid of fleas quickly with CedarCide. Sorry, but nothing can make me put that other stuff on or in my dogs. My tenant had fleas last month despite using a topical app., and we haven’t seen one since. CedarCide treats the whole house. More work than just popping a pill or squeezing a few drops on your pet? Sure, but worth it to me. Until it came in the mail we just kept doing comb-outs every night. I now also use Buddy Wash lavender/mint (lavender is a natural flea repellent) and a neem oil/lemon/filtered water mixture sprayed on before going out.
