10 Whitefly Killer Cards - Encarsia formosa

Encarsia is introduced into the greenhouse / conservatory as small, black dots on cards, which are simply hung on the lower leaves of the plants - the easiest gardening you will ever do!

Control whitefly in your greenhouse / conservatory by introducing Encarsia Formosa AS SOON as the 1st whitefly appear and the temp above 10°C / 50°F.

Encarsia is a natural parasite of whitefly, which lays its own eggs inside the whitefly scale, so instead of a whitefly emerging another Encarsia is born. As Encarsia numbers build up the whitefly are controlled.
