They don't work. They only provide temporary relief. If you only use mite off, you will be constantly battling mites.
I treated my pastel redtail only 2 times and they were gone. the stuff I got DOES work.
Hold on to what is good
even if it is a handful of earth.
Hold on to what you believe
even if it is a tree which stands by itself.
Hold on to what you must do
even if it is a long way from here.
Hold on to life
even when it is easier letting go.
Hold on to my hand
even when I have gone far away from you.
