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.
Product Description
This shiny, dome-shaped beetle is a voracious whitefly hunter, making it a strong pick for active, heavy infestations. 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.
Introduction Rates
Release 1–5 beetles per 10 sq. ft., weekly, for 3–4 weeks (or 100 beetles per "hot spot")
Temperature range: 50–90°F, with 60%+ humidity
Rates are general guidelines. Actual needs vary by pest species, plant, and infestation level. Monitor both pests and released insects to gauge success.
Application
Disperse gently onto infested plants; leave the container open for 24 hours for stragglers to emerge.
Pro Tips
Avoid broad-spectrum or systemic pesticides, which are toxic to these beetles.
