Most Effective Aphid Control:
Aphid Predators (Aphidoletes aphidimyza) 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.
