I just released 4000 predatory mites.
I don't use only persimilis. The requirements on temperature and humidity to keep them alive are too demanding. I use a mix of 4 mites...
P. persimilis, N. californicus, A. cucumeris and A.swirskii
Hopefully, this will help with the survival rate.
Wanna see a battle between them.......
EDIT: Oops. wrong video. Here is the battle scene....
For a predator mite, they sure got their butt kicked by the 2-spotted. I saw ONE battle in 15 minutes, and the predator lost. The 2-spotted walked away after a first round K.O. You could see stars around the Persimilis head like a cartoon.
Holy cow!!! Are these mites supposed to be aggressive?
The video is kind of long (15 minutes) but it took me that long to find a "predator" that wasn't either hiding under a rock. Or, busy running from a 2-spotted.
And, these are supposed to KILL my mite problem??? Doubtful. LOL
They seem to co-habitat well with the 2-spotted, simply walking right over the top of the 2 spotted. Well, the small ones. The Persimilis went way around the big 2-spotteds. LOL
It seemed like they fought among themselves more than against the 2-spotted.
Maybe I just got a batch that just got home from a big Thanksgiving dinner and they were not hungry. LOL
