Amblyseius cucumeris

Amblyseius cucumeris is a generalist predatory mite in the family Phytoseiidae — the thrips specialist of the commercial biocontrol world. This bottle format contains 100% adults in a vermiculite carrier, formulated for a single targeted deployment against an established pest colony. You open it, you release it, it gets to work.

Because the bottle delivers a concentrated adult population all at once, predator-to-prey ratios spike immediately. This is what you want when thrips larvae or broad mites are already visible and causing damage — high numbers fast, before the pest population compounds another generation. The bottle is not a prevention tool; it's a treatment. If you're looking for ongoing 30-day slow release, that's the sachet product.

Cucumeris targets thrips first and second instar larvae — the stage where you break the reproductive cycle — along with broad mites, russet mites, and cyclamen mites. Multiple bottle sizes are available to match your growing space, from small home collections to greenhouse scale.
