A few days after hanging these treatment cards the encarsia formosa emerge to search for whitefly to parasitize. They lay an egg inside the whitefly pupae, which turns it black and kills the whitefly.
The parasitised whitefly pupae then produces a new encarsia formosa wasp to repeat the process and keep your greenhoiuse or polytunnel whitefly-free.
If infestations of whitefly are already noticeable before introduction, apply a spray of Savona or similar fatty acid based product to the heads of the plants prior to introduction of Bio control Whitefly. Introduce Bio control Whitefly before whitefly are in high numbers.

Control whitefly with this natural and trusted control method. These parasitised whitefly pupae contain the parastic wasp of whitefly; Encarsia formosa. These minute wasps emerge from the pupae to search for whitefly pupae to parasitize.
They lay an egg inside the whitefly pupae, which turns it black and kills the whitefly. The parasitised whitefly pupae then produces a new Encarsia formosa wasp.
This process is one of the oldest forms of biological control and has been used for many years, especially by tomato growers.
It has a huge advantage over traditional chemical pesticide control in that the whitefly are not able to become resistant to attack by these tiny parasites.
The 1,500 parasitised whitefly papae are supplied on 50 cards.
