  • Greenhouse Whitefly

    has anyone used biological control for greenhouse whitefly and have any reviews they would like to share. I have seen 500 encarsia formosa wasps for £10.99 on a website but that seems a bit expensive as I am assuming that they have a very short shelf
    life and have to be used within one season ?

    I've used this with good effect (you need more than one spraying, but it does work)

        I always make sure there are plenty of spiders in the greenhouse and the plants are always clean. Any spiders I see in the house are always transported thence.

            Spiders and yellow sticky traps seem to work for me.
