Doing Away With Pests
Someone who keeps calling another person at an unholy hour can be a pest to the latter. But in the context of pest control, we refer to those plants or animals "detrimental to human concerns (as in agriculture or livestock production), from being mere nuisance to the more serious, that of being carriers of germs or viruses which cause epidemic diseases, resulting to high mortality among those that get afflicted. Pest control involves the regulation of the proliferation of these organisms that are perceived to negatively impact people's health, the ecology or the economy.
Pest control can involve: use of pest-destroying animals (such as keeping cats to prey on rats or introducing a mongoose into a house to eliminate rodents and snakes); biological methods (putting bacteria that infects and kills mosquito larvae in ponds, lakes and streams or local water sources); mechanical means (use of hands-on techniques as well as simple devices and natural ingredients that provide a protective barrier); physical removal (e.g., dog-catching with noose and net); breeding grounds elimination (i.e., proper waste and drainage management).
Other methods include use of poisoned bait, field burning, hunting and trapping and use of pesticides. Pesticides usually are used for fumigation, space treatment or pest habitat treatment (e.g., injection into a termite mound to kill the colony). Many chemicals and compounds which have been confirmed to contain substances that could cause human ailments or negatively impact other beneficial flora and fauna are banned for use as pesticides.

Habitat sterilization (like soil steaming) or use of bait to cause pests to become sterile is also used. In forest management, trees that are infected with insects (that cause tree death or stunt tree growth) are cut down and destroyed. Handy rub-on repellent lotions or powders are available to deter mosquitoes and other blood-sucking insects from feasting on people.
Pest control and management specialists develop their techniques using a combination of most of the above methods. Successful practitioners go beyond just being "exterminators". These people or companies at http://www.deadpestz.com/does-peppermint-oil-repel-spiders/ have established procedures to determine what pest or pests currently infest a home, an office, or a particular acreage of land or forest, able to assess the magnitude of the problem and come up with economical, environmentally safe ways of eradicating the pest problem. They provide solutions to prevent recurrence of the infestation and recommend how regular any treatments should be undertaken if necessary.
The emphasis on any pest control and management solution with http://www.deadpestz.com/how-to-get-rid-of-mice/ is that it must be "Ecologically-friendly, Economically viable and effectively Eliminate the pests".
