Enforce™ for Whitefly Control
Enforce™ is a tiny, 100% safe parasitic wasp that specializes in parasitizing whitefly, specifically greenhouse whitefly (Trialeurodes vaporariorum), although it will attack other whitefly species. PRICE: $10.00 per 1000 wasps (10 tags, the minimum order) plus GST and Freight
Beneficial Invertebrates
Encarsia formosa is a tiny parasitic wasp widely used in biological control programs to manage whiteflies, particularly in greenhouse settings. These beneficial insects are effective against various species of whiteflies by parasitizing their immature stages.
Adult female Encarsia formosa wasps lay eggs inside young whitefly nymphs. Upon hatching, the wasp larvae feed on the whitefly nymphs, eventually killing them. This parasitic activity helps reduce whitefly populations significantly over time.
Encarsia formosa is particularly suited for use in enclosed environments like greenhouses, where it can provide continuous control of whitefly populations without the need for chemical insecticides. They are known for their ability to seek out and parasitize whitefly nymphs efficiently, making them a valuable tool in integrated pest management strategies.
These beneficial wasps are safe to use around plants, animals, and humans, and they do not cause any environmental harm. They are an important component of sustainable pest control practices, offering growers an effective and environmentally friendly solution to whitefly infestations.
Same week delivery is not guaranteed as products are subject to availability. If unsure, please contact Bioforce directly, although be assured that we always aim to deliver as promptly as possible.

Enforce™ tags are sent via fast-post or courier (at the customer’s request).
100 viable Enforce wasps will emerge from each tag
| Wasps per metre squared: | ||||
| Infestation | Cucumbers | Ornamentals | Tomatoes | Vegetables |
| Preventative | 2-6 | 1-3 | 1-3 | 1-3 |
| Light | 6-12 | 3-6 | 3-6 | 3-6 |
| Heavy | 12+ | 9+ | 9+ | 9+ |
It is recommended that Enforce™ is introduced regularly when whiteflies are present, initially at a minimum of every 2 weeks over at least an 8 week period.
Monitor your plants once a week, and after four weeks black ‘scale’ should be present. When 80% of the ‘scale’ is black, the release rate can be re-evaluated.
Tags can be concentrated in greenhouse whitefly ‘hotspots’ within your crop. Enforce™ adults are able to fly about 20 metres and disperse readily.
Higher release rates may be required during the winter when temperatures are lower and control is more difficult.
- Do not touch the black ‘scale’ on the tags
- Do not expose the tags to direct sunlight
- Hang the tags immediately within the crop,
- If the tags must be stored, store them in darkness at 10-15 ° C.
- DO NOT REFRIGERATE
- Do not store the tags for more than 2 days
- Tags come in strips of up to 10; tags should be separated and hung individually
- Hang tags one metre below heads of crop, so the wasps work upwards
- Hang tags in shade
- Ensure tags are hung in different places each week
- Tags should be distributed evenly through the crop
- Leave tags in crop for at least 14 days
After three weeks it is safe to assume all Enforce wasps have hatched, so the tags may be removed if desired.
Within four weeks of release, black ‘scale’ should be present within your crop, on the lower leaves of your plants. Adult wasps should emerge within 2-3 weeks.
Before introducing Enforce into your crop, please check residual chemical effects and ensure you know chemical compatibilities and products that may be applied.
