I don't know what has happened to the search bar in this forum so forgive me if this is posted elsewhere. Does anyone have any experience with these collars that emit an ultrasonic pulse to repel fleas? I'd like to know how well they work if at all. I'm sick of putting these chemical compounds on my cats. On a related note, has anyone ever used diatomaceous earth to control fleas on their pets and in their environment? Many thanks in advance and if anyone knows of any other "chemical free" alternatives that are safe and that work, don't hesitate to mention them.
