Predatory Mite
Microscopic mites, invisible to the naked eye, that prey on spider mites, thrips larvae, and fungus gnat eggs. Invisible to the naked eye but highly effective at suppressing pest mite populations.
Why you want them
Predatory mites are the natural check on spider mite populations. In a garden that avoids broad-spectrum pesticides, predatory mites keep pest mite numbers in balance without any intervention. They move faster than prey mites, locate them efficiently, and can consume several prey per day. Where spider mites become a persistent problem indoors or under cover, predatory mites can be purchased and introduced - but supporting the conditions for wild populations is the more sustainable approach.
Helps control
How to attract them
- Avoiding pesticide use
- Humid conditions
- Dense planting that retains moisture
Preferred habitat
On leaf surfaces and in the dense environment of plant foliage. They thrive in humid conditions and are most abundant on plants grown in mixed, sheltered plantings.
What harms them
Any broad-spectrum pesticide or acaricide - even "organic" options like sulphur sprays - will kill predatory mites alongside pest mites. Dry, dusty conditions also reduce populations.
