Anyone here used Amblyseius (Neoseiulus) californicus or andersonii? Most of the RSMP
available is Phytoseiulus persimilis, but it isn't effective at low temperatures.

Been using Amblyseius here for four years and swear by it.
It overwinters here quite readily and all that I do is to top up
every spring. Greenhouse is kept just frost free in the winter.
