Dear Dr. Audrey,
I’m looking for a way to control fleas and wondered if your clients had good luck with ultrasonic flea collars.
A study was undertaken at the Purdue University in Indiana in the late 1980s and the results were published in the Journal of the Acoustical Society of America. It showed that ultrasonic collars were not at all effective in repelling fleas on cats, and I can see no reason why the results would be the same on dogs.
I can appreciate people being worried about using chemicals on their dogs, but buying one of these devices may just be a waste of money, and you’re likely to still have a flea problem.
Frontline and Advantage applied monthly are still the best option for keeping fleas off your dog. Comfortis is a new product that is given by mouth once a month, and it is extremely effective at killing fleas. I think your dog would be more comfortable if you invested your hard earned dollars into something that has been proven to be effective.
