Hi, I have several outdoor cats and was wondering what to do regarding fleas. Only one of them lets me touch her and I plan on using Advantage drops on her. Her kittens are about 5 months and I'm not sure what to use since we still can't pick them up. I have been reading about Capster but it just kills the fleas on them and isn't a preventative. They have blankets in my garage that I plan on throwing out since it's warm now. What should I spray to kill any lingering fleas in the garage? The cats are still allowed in there. It's getting warmer and I want to have a plan to battle fleas before they become a huge problem!
