In the beginning it was the holy grail... but it turns out
1. ear mites die out
2. male spider mites stop coming to your body, so it's ineffective: they have sex somewhere else
3. itch mites love it, and use it to explode their population
Now, I would call this a successful test, but a huge failure.
EAR MITES: So, if you have ear mites, use them until the ear mites die out, on yourself and on your pet.
SPIDER MITES: If you have spider mites and you are not very diligent with your ginger tea: continue using it, but make sure you drink enough ginger tea, every 2.5 hours, including at night
ITCH MITES: stop using Neem. I don't have a solution yet, but Diatomaceous Earth looks good at the moment... spread out on the floor, carpets, furniture, very thinly. Stay tuned as I am tesing.
