Insect Control and Bug Problems

There are many species of insects. The vast majority pose no problem and make a positive contribution to the interesting fauna of the region. Insect numbers are normally kept in reasonable bounds by unfavorable weather conditions and by various insect and animal predators. Still, a few species do at times, mar the beauty of the landscape and others reduce the gardeners’ supply of vegetables, fruit, and flowers. To minimize such losses, gardeners need to understand insects. Control without understanding in neither desirable nor feasible.
