We had a flea infestation 3 years ago after thinking that cheapy flea treatments would work. Ever since, we've treated the house with Indorex every year and been religious with applying Advocate (prescription only) every month. Over the last week I've found three fleas, thankfully all very nearly dead, either on or near one of my two cats. I am getting a bit paranoid that the treatments aren't working. I know the flea has to jump on the cat for it to work, so I can accept seeing one flea a couple of times a year, but three in a week? Should I be panicking?!
