Anystis are a large, fast, red mite that are quickly becoming a popular bio-control agent everywhere from indoor house plants to agriculture, floriculture and retailers. It is already being used for both generalist preventative applications against pests as diverse as whitefly, red mites, and psyllids and to wipe out (or prevent) known pests like thrips, aphids and spider mites.
These “Crazee Mites” require such large numbers of prey that they are quick to spread out and may cannibalize if there is a lack of food. All mobile stages of Anystis are predatory. The adults will immediately begin laying eggs and are capable of eating hundreds of prey daily. Eggs are laid in leaf-litter or loose, consistently humid growing media, making cycling possible in most crops. Some others may require regular reapplications.
Aphid control is best achieved with preventative applications of Crazee Mites as needed, and regular preventative releases of Aphidoletes every 2-3 weeks during peak aphid season.
Application rates are variable. 1 mite per square foot may be appropriate for both preventative and knockdown depending on environment, plants and prey. Generally, as a starting point, it is recommended that 0.25 mites be applied per square foot for prevention.
