Biological control of glasshouse leafhopper

To naturally control leafhoppers, encourage predators such as birds, ladybirds, wasps, and ground beetles into the garden. Plant nectar-rich, flowering plants to attract them, such as buddleia, calendula, sedum, stock, sweet William and wallflowers. Get a head start by growing a small patch of nettles to shelter predators. Cut the nettles back when leafhoppers appear in other parts of your garden to encourage the predators to seek them out.
