What's in the Sachet

Each sachet holds 250 persimilis packed in all life stages, for a steady flow of predators for 2-4 weeks. Hang it on the plant and the mites walk out on their own.

How Persimilis Works

P. persimilis was one of the first predatory mites used in pest management. It's a Type I specialist that eats only spider mites. Adults are about 0.5 mm long, pear-shaped and bright orange to red. Females lay eggs inside spider mite colonies, including in the webbing; eggs hatch in 2–3 days, the larvae don't feed, and the nymphs and adults eat spider mites at every stage. An adult female can eat up to 40 spider mite eggs a day above 68°F. At 70–80°F it goes from egg to adult in about a week, roughly twice as fast as spider mites, and each female lays up to 60 eggs over her lifetime.

Where It Works

Vegetables, hemp, strawberries and other soft fruit, and ornamentals, in greenhouses, indoor grow rooms, interior plantscapes and outdoor crops. Persimilis eggs need humidity above 60% to hatch.
