And these days there is an insecticide available for every bug. Your garden is part of a complex ecosystem in which plants and animals interact on many levels. When you try to eliminate one particular weed or insect, the results may not be what you expect. Garden pesticides can kill bees and other beneficial insects, birds, and earthworms. They can contaminate nearby streams or ponds directly or through runoff.
Chemical controls can backfire when insects develop resistance and become more difficult to control.
There are many effective strategies for preventing and minimizing pest damage without using toxic chemicals. Just keep in mind that the complete elimination of pest damage is not realistic or even desirable. Cabbage loopers are one of the garden pests that can be quite easily removed by hand. Overall Philosophy Insect management should begin when you plan your garden or flowerbeds. A little extra thought at this stage can reduce your headaches later.
