STORAGE: Highly perishable, should be used immediately upon delivery. If storage is absolutely necessary, refrigerate at 50� F. (6�-10� C). Not to exceed 2 days, to minimize mortality.
AUGMENTATION: Release rates are being developed. Release at least one per plant or one per square foot in greenhouses at the first sign of spider-mites. Later releases will require much higher numbers to be effective.
NOTES: This predatory mite disperses quickly. Neoseiulus fallacis is known to control European Red Mite below economic thresholds in fruit tree orchards. it is also being successfully used in mint fields.
