Delphastus catalinae | Whitefly Control

Target Pests Greenhouse, silverleaf, sweet potato, banded-winged, and most other whitefly species. Also feeds on citrus blackfly, spider mites, and aphids when whiteflies are scarce.

Unlike many predators, it stays active year-round with no seasonal dormancy — great for consistent indoor or outdoor use. Pair with Encarsia formosa and Eretmocerus eremicus for full-spectrum control across light, moderate, and heavy infestation levels.
