Spider Mite Control
- Phytoseiulus persimilus
- Amblyseius californicus
Predatory mites can be very successful in controlling spider mites as they will multiply nearly twice as fast as the spider mite population. As a preventative measure, introduce Phytoseiulus persimilus at the rate of 1 predator for every 5 sq.ft. of greenhouse area, just after transplanting. Repeat this two weeks after transplanting. Repeat this two weeks later. For control of an existing problem introduce at the rate of 1 predator for every 25 to 50 spider mites. The more you introduce, the quicker you will gain control.
