this is exactly what we thought when we were fighting a bird mite infestation! It was totally unbelievable and made it very obvious how massive epidemics have occurred in the past.
It made us very passionate about all-natural agents, as they seem to never lose their effectiveness--the bugs never adapt to them.
We have sort of honed in on a basic 5 that truly seem to work:
borax
epsom salt
tea tree oil
diatomaceous earth
apple cider vinegar
We were so shocked when it happened to us and fortunately we were able to clear our infestation up in about a month. When I read stories of people who had been dealing with this for years, it made my skin crawl.
So much of this information is so hidden and should be brought in to the open!
With these 5 tools and excellent diet, I think you can cure just about anything!
