Instead of using pesticides, gardeners can rely on the natural
enemies of pests to keep them under control.

•many of the native animals attracted into a ‘greener’
garden will feed on pests; frogs and toads will eat slugs;
thrushes devour snails; blue tits relish aphids
• simple brightly coloured flowers like marigolds attract
beneficial insects such as hoverflies and ladybirds. These
insects will feed on aphids
• insect pests in glasshouses can be controlled by
releasing selected predators (available from garden centres
or by mail order); Phytoselius mites attack spider mites,
Encarsia wasps parasitise whitefly
• an application of a special nematode (available from
garden centres) can reduce slug populations and the damage
they cause
• caterpillars can be controlled with a fungal spray
