I use the vinegar as a carrier and I just use it straight [mixed with the oils], but you and I both know it ain't the most pleasant smelling stuff on the planet ;(, so if you wanted to dilute it I'm sure it would still work.
Coincidentally, I was just reading something on another forum. This lady is using 'rosemary' as a repellent for mites on her hamsters. I guess she uses it regularly as a pest repellent on different pets for various pests. I'm thinking of trying it out. I was going to use it as a 'rinse' after bathing my dog and see if that helps with the fleas.
I had to break down recently and use a chemical flea killer on my dog, as she has developed an allergy [apparently] to flea dander. She was beginning to develop hot spots on her back from itching. I told the vet she only had one or two fleas [we flea comb her regularly], but apparently that was enough to cause a breakout. So I reluctantly gave her the medication to buy myself a little time to get ahead of the situation, but I don't want to rely on this.
The oils I mentioned above have worked well for me in the past, but I will admit I still saw the occasional flea on her. I never thought that to be much of a problem. It was a welcome trade off to over-the-counter chemicals. As long as she wasn't infested with them I could stay ahead of the game, but now apparently one flea is one too many, arghhhh!
Another reason I mentioned the vinegar as a carrier is because it won't leave your dog all greasy/oily like the oil based spray will, and vinegar will make her coat nice and shiny. Heck I have used it on my own hair as a rinse in the past.
