One can buy chemicals, i.e. poison, to control just about every garden visitor, but they have many drawbacks. There is always a risk of killing useful or harmless creatures as well as pests. Killing useful creatures, such as ladybirds, may actually lead to an increase in the garden’s aphid population and a tendency to use ever increasing doses of insecticide. Although most modern pesticides break down rapidly in the soil, heavy applications may lead to a build-up of residues that can damage the soil and enter the food chains, where they can have far-reaching and surprising effects. Killing harmless creatures does have a knock-on effect by denying birds and other animals their natural food, so your garden will be much less interesting. The true wildlife gardener uses non-poisonous means to discourage or get rid of pests. Aphids, for example, can usually be controlled simply by squashing them with your fingers.
