Controlling pests does not only involve spraying or baiting with pesticides, or using traps. The overall approach to eliminating pest infestation is to identify the contributing factors and work on these drivers. The approach begins with the determination what organisms could exist in the environment where man conducts his daily activities and the hazards these organisms pose. Knowing what makes these organisms thrive, determines the solutions for negating the conditions that make it conducive for these organisms to breed and survive in a particular environment.
Pests can bite or sting, and could carry life-threatening pathogens for humans as well as pets or livestock. There are organisms that become pests when these adversely affect agriculture by devouring plants and grain, or also carry microbes that hinder/kill vegetation growth. Rabid feral dogs and cats could pose a threat. Birds can have dangerous microbes in their excreta. Many love pigeons in the park, but these could really damage gutters or roofing with accumulated droppings. There are animals which are not pests in their natural habitats, but could become bothersome when these enter human habitation (like bears, snakes, alligators, etc.). In most of these situations, animal control specialists are called in to control these “pests”.
Most pest control services, however, cover rats and crawling, migratory or flying insects (some parasitic): termites, cockroaches, ants, fleas, tics, mites, flies, wasps, or mosquitoes. Generally, these can do serious house damage, spoil/consume food supplies or have nasty bites/stings that may even be poisonous. Others harbor pathogenic organisms that could cause epidemics.
Part of the construction works for a house or facility, includes engagement of pest control service providers who design and implement a termite control system under and around structures. The system makes it possible to do periodic soil treatment with safe pesticides through “fill-points” (as opposed to the older method of one-time soil treatment before the foundations or flooring are laid).
Baiting systems for crawling insects also make it possible for insects to carry the pesticides back to the nests or colonies. Active ingredients in cockroach poisons are also passed on to other roaches that feed on those that die from the poison, thus increasing the effectiveness of these pesticides. Long-lasting sprays and fogging kill most flying insects, but eradication is best achieved by eliminating breeding areas.
Rodenticides used by most pest control services not only kill rats, but flush these vermin out to avoid bad odor from rotting carcasses in vents or ducts. Pest control service providers not only bait or trap rats, but help identify and eliminate possible nesting areas as well as food sources. Usually, infestations substantially decrease when rodents move out from a home or facility because these are denied food sources. Proper maintenance of garbage bins, regular cleaning of kitchens free from food scraps, securing foodstuff in pest-proof containers and avoiding stacks of paper in boxes help keep rodents away.
