Alianza is a biological-control insectary outside Girona, founded in 2015 by entomologist Núria Bastida and her partner, Marc Esteve. They breed and ship predatory mites, ladybug larvae, lacewings, and parasitic wasps for organic growers across the EU. Every release pack ships cold-chain and arrives at the door within forty-eight hours of leaving the insectary. Releases work — and Núria will walk you through the timing on the phone if you ask.
