Aphid Predators (Aphidoletes aphidimyza) (aphid midge) have worked so well in many greenhouses, that, by Summer, Aphids may be hard to even find. Breeding populations of predators are usually established from a single release, but regular weekly releases during the growing season speeds up control. 1,000 Aphid Predators treats up to 10,000 sq. ft. of greenhouse space.

   Special Species Notes: Aphid Predators have a soil-resting phase as part of their lifecycle, so should not be used at the same time as Predatory Nematodes .

   Application: Aphid Predators are shipped to you as cocoons, waiting to hatch, packaged in bottles. Spread the contents on the soil or leaves.

   Handy Hint: In greenhouses, a few specimen house plants kept all year long, in addition to the main crop, can be major sources of infestations. Check any year-round specimen plants particularly closely for pests.
