I was wondering if anyone knows of any natural or home remedy ways to get rid of fleas. I have a close neighbor, a sweet kind elderly woman, with a major cat problem. I'm talking 30-40 cats feral cats roaming around. I'm trying to work with the humane society to get rid of them....meanwhile, they are creating a major flea problem in our yard this summer, hot as it's been. I have a 8 year old rottweiler, Mack, who weighs about 90 lbs. I have frontline for the 89-130something lb dog, but he is still miserable with the fleas. Mack lives inside, just goes out when I feed the critters and to potty. He's spoiled rotten and I can't stand to see him suffering I've tried switching to the advantix as well, but I think there's just such a crazy amount of fleas due to the cats that it overwhelms the flea medicine. He's miserable and we're miserable watching and listening to him scratch and bite all the time! So, I was wondering if anyone knew something to treat the fleas, either on the dog, in the house, and/or in the yard. I prefer something natural, especially in the yard due to the chickens pecking around.
