Phytoseiulus persimilis is a predatory mite that feeds only on two-spotted spider mite adults, nymphs, and eggs. Because spider mites are their only food source, Persimilis are best introduced when spider mites are first discovered, rather than preventatively. Once they exhaust their food source they will disperse or die of starvation. Persimilis do not go into diapause and are capable of complete eradication of spider mite populations if climate conditions are suitable

How It Works

Adults and young stages feed voraciously on all two-spotted spider mite life stages.

Effective at wide temperature range above 57°F and can be used outdoors as well.

At temperatures over 86°F, spider mite growth rate will overtake that of Phytoseiulus.

Less active at low light levels but will not go into diapause.
