Some varieties of plants are particularly susceptible to insect damage, while others are less so. This can come about naturally – a variant which is less tasty to bugs, for example – or, in some cases by direct modification, such as BT corn and other crops, which actually contain a natural insectide. Without getting into the merits of genetic modification, it’s preferable to choose resistant varieties when possible.
Also, different species can sometimes be planted together to solve an insect problem. For example, planting marigolds in your vegetable garden will keep away squash beetles, Mexican bean beetles, and nematodes; peppermint repels ants; and garlic protects against fleas, Japanese beetles, and spider mites. (And vampires, of course.)
When you must use a pesticide, always try to find the one that works best against the specific target. Apply it carefully, and always read and follow the label directions. Dispose of any residues properly.
