Amblyseius cucumeris - FAQs

Is it too cold to release A. cucumeris in early spring?
A. cucumeris can remain active in relatively cool conditions, but development and reproduction slow as temperatures fall. For best establishment, aim for 66–80°F when you can.

Why use A. cucumeris before I even see thrips?
Thrips hide in buds and leaf folds, so damage usually appears after the population is established. A. cucumeris can live on pollen until thrips arrive, so releasing early puts predators in place to catch the first larvae before they multiply.

Can I use A. cucumeris with neem oil or insecticidal soap?
Not while predators are present. These products can kill predatory mites through direct contact, and some treatments may remain harmful after the spray has dried. Check which chemicals are safe for predatory mites and observe the recommended re-entry/release interval before introducing predators.

Are A. cucumeris predatory mites safe for people, pets, and plants?
When used as directed, yes. A. cucumeris isn't known to bite people or pets, and it doesn't feed on plants. It eats small pests and pollen, and its numbers fall once food runs out.

What are the other tiny mites in my sachets?
Those are feeder mites. They're harmless and don't eat plants. They're packed in with the cucumeris as an instant food source, so young predatory mites have something to eat while they develop.
