Bright orange and just large enough to see, each one eats about ten adult spider mites a day, or twenty eggs and larvae. It walks straight into the webbing that stops other predators and works the colony from the inside.\u003c\/p\u003e\n\u003cp\u003eIt is also about as simple as pest control gets. Nothing to mix, nothing to spray, no residue on the leaves and no re-entry interval — you tip them onto the plant and leave them to it. They hunt the undersides and the crevices where a spray never lands, they find the colony without your help, and spider mites cannot develop resistance to being eaten. Safe around people, pets and anything you plan to eat.\u003c\/p\u003e\n\u003cp\u003eTwo things decide whether it works. It wants humidity — 60% or higher, sustained — and it wants spider mites to eat, because that is the only thing on its menu. In a dry room \u003cem\u003eNeoseiulus californicus\u003c\/em\u003e is slower but holds on at 40%, and on a plant with nothing to hunt persimilis will not linger.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBest for:\u003c\/strong\u003e An active two-spotted spider mite outbreak with visible webbing or stippling, in humid conditions.\u003cbr\u003e\u003cstrong\u003eHow many:\u003c\/strong\u003e Sizes go by plant count.
