Fallacis is an extremely effective spider mite predator. It is the most effective preventer of spider mites available. In long term crops usually one application at a rate of 1 to 2 mites per square meter is enough to achieve multi-year spider mite control. In starving conditions, fallacis is a generalist, capable of feeding on many other pests, especially their eggs. If no pest is present, fallacis will survive on wind-blown pollen.

In outdoor applications, it is best applied at the end of the summer, allowing it to build up slightly, then over-wintering with the pest. We have not found a mite that fallacis will not control.

Fallacis is comfortable walking on the ground, so it will disperse evenly throughout any crop.
