Pest Control Types
Organic pest control
While chemical pesticides may kill insects effectively, some may also be toxic to
human beings and lead to severe environmental degradation if their use is not properly
managed. By comparison, natural pesticides, which are usually eco-
Elimination of breeding grounds
Proper waste management and drainage of still water, eliminates the breeding ground of many pests.
Garbage provides food and shelter for many unwanted organisms, as well as an area where still water might collect and be used as a breeding ground by mosquitoes. Communities that have proper garbage collection and disposal, have far less of a problem with rats, cockroaches, mosquitoes, flies and other pests than those don't.
Open air sewers are ample breeding ground for various pests as well. By building and maintaining a proper sewer system, this problem is eliminated.
Field burning
Traditionally, after a sugar cane harvest, the fields are all burned, to kill off any insects, or eggs, that might be in the fields.
Poison spray
Spraying poisons by planes, hand held units, or trucks that carry the spraying equipment, is a common method of pest control. Throughout the United States of America, towns often drive a town owned truck around once or twice a week to each street, spraying for mosquitoes. Crop dusters commonly fly over farmland and spray poison to kill off pest that would threaten the crops. Many find spraying poison around their yard, homes, or businesses, far more desirable than allowing insects to thrive there.
Destruction of infected plants
Forest services sometimes destroy all the trees in an area where some are infected with insects, if seen as necessary to prevent the insect species from spreading. Farms infested with certain insects, have been burned entirely, to prevent the pest from spreading elsewhere.
