And you won't be eliminating all the beneficial bugs.
Research indicates that plants produce excessive foliage and can afford some pruning.
Natural pruning by insects can improve yields and increase the vitamin content of fruit in certain plants. A certain relationship exists between plants, and between insects and plants. Companion planting is the usual name given to the practice of planting according to these relationships, but actually four different practices are involved. Certain plants such as marigolds, mints and garlic are offensive to some insects, and will deter them when planted near other plants. Combinations of plantings produce crops that grow better and are healthier because of their proximity.
