First off let me say that Earth Clinic is my "go to" site for getting informaion and answers and help. It is my starting point on whatever questions I might have. - I start here, google what I've found, and end up right back here again. This is an amazing community of people helping people.
I have recently had a bout of fleas on my poor dogs. There were only a few so I didn't know what it was for a couple of weeks. I kept checking them for fleas or mites, but never saw anything. They were miserable, would welt up, then get better. Then the cycle started all over again. After discovering the fleas, I did a test. In small, separate containers I put, hydrogen peroxide, aloe vera juice, white vinegar, and apple cider vinegar. I deposited a few fleas in each container. Surprisingly, they lasted less than 5 seconds in the aloe vera juice! The others took considerably longer... They swam in the white vinegar for about 20 minutes, in the ACV for about 5 minutes, and in the hydrogen peroxide for about 5 minutes. I had a 1 gallon container of organic 100% aloe vera juice so gave both boys a sponge bath in it... Really soaked them down. The welts have diminished quite a bit and they are finally resting comfortably.
