› Grower guide More information about Whitefly Control
Clear whitefly at the source — with parasitic wasps and predators that destroy nymphs before they become breeding adults. No residue, no resistance, no endless spraying.
Whitefly resistance to insecticides is widespread, and their eggs and nymphs hide on the leaf undersides where sprays miss. Whitefly biological control solves both: tiny wasps and mites hunt whitefly where they live and multiply into self-sustaining control. Encarsia formosa for whitefly and Eretmocerus eremicus are the proven backbone, ideal for long-term crops.
Why choose biological whitefly control
Parasitic wasps are invisible on the crop, safe for pollinators and staff, and perfect for organic and IPM programs — reaching the undersides of leaves where sprays can't. Released early and often, they keep whitefly below damaging levels all season.
How to build your whitefly program
Identify your whitefly species first to pick the right wasp and rate. Hang parasite cards on lower, shaded leaves and release while counts are low. Encarsia excels on greenhouse whitefly in cooler houses; Eretmocerus tolerates higher heat and tackles both greenhouse and sweetpotato whitefly. Add swirskii mites to eat the egg stage, and watch for blackened (parasitized) scales as proof it's working — once ~80% are parasitized, the wasps hold the line on their own.
What's in this collection
- ENCARSIAforce (Encarsia formosa) — parasitizes greenhouse whitefly nymphs.
- ERETforce (Eretmocerus eremicus) — heat-tolerant wasp for greenhouse & sweetpotato whitefly; ENCAR/ERETforce combo for mixed infestations.
- AMBLYforce S swirskii mites for the egg stage, plus CHRYSOforce R lacewings and SuffOil-X for knockdown.

Frequently asked questions
What is the best biological control for whitefly?
Encarsia formosa for greenhouse whitefly and Eretmocerus eremicus for warmer conditions or sweetpotato whitefly — often used together, with swirskii mites for the egg stage.
How does Encarsia formosa control whitefly?
The wasp lays eggs inside whitefly nymphs; parasitized scales turn black and produce more wasps instead of more whitefly.
How long does it take to work?
Allow a few weeks for parasitism to build; once over ~80% of scales are parasitized, the wasps keep whitefly in check on their own.
Are whitefly parasitic wasps safe?
Completely — they're harmless to people, pets, and pollinators, target only whitefly, and leave no residue.
