Amblyseius andersoni Sachets - FAQs

Why hang sachets before I even see spider mites?
Spider mites multiply fast in warm weather, so you usually spot stippled leaves after the colony is established. Andersoni can live on pollen until mites arrive, so early sachets have predators waiting.

How long does one sachet last?
Plan on replacing it every 2–4 weeks. Swap it sooner if it has dried out or gotten soaked.

Can I hang sachets in fall or winter?
As days shorten in early fall, A. andersoni can go dormant and stop hunting until temperatures and day length improve. For fall releases, a warm, well-lit greenhouse or grow room is the best fit.

Can I use sachets 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 wait the recommended interval before hanging new sachets.

Are andersoni sachets safe for people, pets and plants?
When used as directed, yes. Andersoni 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.
