Stethorus punctillum


Key Features

Stethorus punctillum is a specialized spider mite predator in the lady beetle family. Adults are tiny and oval shaped, 1/10 in. long, dark brown to black in color, with brownish-yellow antennae, mouthparts and legs. Larvae are slow moving, grey with conspicuous legs. They move from plant to plant on leaves. Eggs are yellowish ovals, laid singly in or near mite colonies. Adult beetles can fly, and have an unusually good ability to find small infestations of spider mites.

How it Works

 When combined with other biological control agents such as predatory mites, Stethorus can improve the management of a variety of pest mites in greenhouses, interior plantscapes, and nurseries. Optimum conditions are moderate to high temperatures of 67-90°F. They may remain active and feed, but will not fly at temperatures below 54°F. 

Stethours in cannabis is one of your only options for spider mite control in the flowering stage as it is not deterred by the trichomes and stickiness of the plant. 100 per week, per room, when flowering, may be your best option when it comes to biocontrol use.
