I'm freakin out. I was sitting here reading some posts and my feet are iching. I figure skitter bites so I'm reading and I'm scratching and then I feel a bite. I look at my foot and not 1 but 2 fleas are biting the crap out of me. How do I kill fleas that are in my carpet???? My 4 male cats are the ones bringing them into the house. What do I use on them to kill the fleas?
