By the time you see webbing or stippling the colony is established, and this sachet is for the weeks before that — a rolling population of predators sitting on the plant, waiting.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003ePhytoseiulus persimilis\u003c\/em\u003e is an obligate specialist: it eats spider mites and nothing else. That single-mindedness is what makes it the fastest thing in the catalogue against \u003cem\u003eTetranychus\u003c\/em\u003e — it walks straight into webbing that stops other predators and works a colony from the inside.\u003c\/p\u003e\n\u003cp\u003eRunning it takes about ten seconds. Nothing to mix, nothing to spray, no residue on the leaves, no re-entry interval and no dose to get right — you hang it on the stem and leave it. Because the mites stay contained until they exit, there is no loose bran or vermiculite on your foliage, which matters on flowering plants and on tissue culture coming out of a flask. Nothing to keep children or pets away from, and spider mites cannot develop resistance to being eaten. Safe around people, pets and anything you plan to eat.\u003c\/p\u003e\n\u003cp\u003eThe honest limit of a specialist in a preventative sachet: on a plant that is genuinely clean, the mites that emerge will eventually disperse or die off, because there is nothing else on the menu. The protection comes from replacing the sachet, not from a population that settles in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBest for:\u003c\/strong\u003e Keeping spider mites off high-value plants you would rather not have to rescue.
