Spider Mite Control

Phytoseiulus persimilis Our most popular mite control Two-spotted spider mites and many others are the target food of P. persimilis, which will consume 5-10 pest adults or up to 20 pest eggs/day. When released during a low infestation, spider mites can be controlled within 2-3 weeks. P. persimilis need a relative humidity greater than 60% in order to survive, especially in the egg stage. Once the adults' food supply dwindles, P. persimilis die. If reinfestation occurs, P. persimilis must be reintroduced, preferably every 3-5 weeks, or in combination with either G. occidentalis or N. californicus. Release rates: for tomatoes and cucumbers, 1 predator/plant plus 1-2/infested leaf; for other greenhouse crops and tropical plants, 2,000/3,000 sq. ft; for bedding plants, 1,000/10,000 sq. ft.; for large agri-business, 5,000-20,000/acre depending on infestation.
