Pest control is the process of reducing pests to acceptable levels through prevention, suppression and eradication. Effective strategies include frequent and routine monitoring of pest populations, and the use of relatively low-risk chemical products like traps or baits that don’t harm natural enemies.

Preventive measures include eliminating clogging and clutter that provides hiding places for pests, and caulking cracks to close them in. Chemical controls can be used to kill or inhibit pests from eating, breeding and moving, including plant disease organisms.
Pest identification is the first step in Integrated Pest Management (IPM) and a vital part of the pest control process. A correct diagnosis of the problem helps to develop a more targeted approach for pest management, minimizing off-target damage and maximizing effectiveness. Proper pest identification also provides critical information about the pest, such as where it is found in the environment, how it reproduces and what conditions favor its development and growth.
Pests can be frightening and intimidating to many people, especially when they appear in our homes and gardens. They may bite or sting, such as bed bugs, fleas, cockroaches, ants and house centipedes. Some contaminate food, like fruit flies and grape leafhoppers, or cause staining, such as boxelder bugs and pine seed bugs. Others cause allergies, such as bee stings and cluster flies. Others destroy plants and personal items, such as ants, earwigs and spiders.
Many pests change appearance throughout their life cycle, from eggs to larvae, to adult forms. Proper identification allows us to distinguish these physical changes and determine the most effective control tactics.
For example, a chrysanthemum leafminer will look very different in its early stage of development than in the late stages. If the pest is identified correctly, we can time treatments to the most susceptible stage of development and prevent a costly infestation.
Some pests are more difficult to identify than others, but it is possible to make a positive identification with some help. Your local County Extension Service or State land grant university has experts available to assist you with identifying the pest in your field, garden, landscape or home. There is usually a small fee for this service, but it is well worth it.
Another option is to purchase a pest guide for your specific location. These guides include a list of common North American pests that can be found in collections, as well as photos and detailed information about their characteristics, habits, habitats, threats and prevention and control methods. One example of a comprehensive pest and rodent guide is Insects Limited, which researches, tests, develops, manufactures and distributes pheromone products and trapping systems for insects in a global marketplace.
Prevention
Pest prevention is the practice of preventing pests from damaging or spoiling crops, products and property. It is generally less costly than treatment of an infestation after it occurs, and it is also safer for people and the environment. Preventive measures include inspecting buildings and their surroundings to identify and remove conditions that encourage pest activity, such as food, water and shelter sources. It also includes sanitation, which means regularly removing debris and trash and keeping areas neat, tidy and free of places where pests can hide.
Prevention is also a vital component of integrated pest management (IPM) programs. This approach focuses on treating only those pests that have been identified as problematic, rather than all pests in an area or facility. Treatments are targeted, and use of chemical controls is minimized. This is because the goal of IPM is to achieve pest control without using excessive or inappropriate chemicals.
For example, a small number of wasps flying around a yard are not a serious nuisance and probably do not need to be controlled, but a large nest in a nearby tree may require removal or other action. Similarly, monitoring and scouting for pests can help determine whether a problem exists or not. In a garden or field, this might involve checking traps and bait stations for activity; in facilities or homes, it might mean examining a crawl space, foundation, or cracks for signs of pests.
Many factors affect pest populations, influencing their rate of growth and the damage they cause. Some are related to weather conditions, such as temperature, day length and humidity, and some are related to the growth of the pest’s host plants. Other factors, such as the presence of predators or parasites, may reduce pest populations. Biological methods of control, including the release of natural enemies and sterile males, can also reduce pest numbers.
The best way to prevent pests is to provide a hostile environment for them, by removing conditions that attract them. For example, eliminating clutter and hiding places may deter rodents, while keeping garbage in a tightly-closed container can prevent cockroaches. In addition, storing food in sealed containers and maintaining good hygiene practices will discourage pests from entering a building. Repellants, either sprays or granules, can be used to repel some pests, but they should be applied sparingly and according to the product label’s directions.
Treatment
A pest that transmits disease, destroys property or disrupts natural processes should be eliminated as soon as it becomes a nuisance. This may be done by killing it or removing its eggs or larvae with a variety of methods including spraying, baiting, trapping and eradication techniques.
The first step in pest control is an inspection to identify the problem and determine its extent. Then, a customized treatment plan is developed to address the specific problems and prevent them from occurring again. The plan might include interior and exterior treatments such as spraying, baiting or dusting, as well as sealing cracks and crevices where the pests are gaining entry into your home or business.
If the pest is a continuous nuisance, it might be necessary to use an insecticide to kill it. Pesticides can have a negative impact on the environment and human health, so it is important to take steps to minimize their use, if possible. The goal should be to reduce the number of pests to a level you can tolerate, and only use chemicals when the pest population exceeds that threshold.
Pests often have natural enemies that limit their numbers and damage. These enemies might be predatory birds or mammals, parasitic insects or plant pathogens. Biological controls can be used to augment the natural enemies in a particular area, or new enemies introduced that were not present there before. A classic example is the introduction of nematodes (microscopic worms that live in the soil) to reduce the numbers of cockroaches and other pests that damage crops.
Weather conditions can also affect pest populations directly or indirectly. Drought, freezing temperatures, rain or other adverse weather can kill or suppress them. The growth rate of their host plants can also influence their development and behavior, affecting the amount of damage they cause.
Sanitation practices can prevent and suppress many pests by eliminating their food sources or shelter. This includes regular garbage removal to stop the spread of pests from one location to another, limiting access to food and water by reducing clutter, and using pest-resistant materials for plantings.
Eradication
When the word “eradicate” is used in a pest control context, it means to destroy every trace of a disease-causing microbe and make it impossible for it to return. This is an enormous task and one that is often compared to eliminating polio.
Eradication involves a complex series of controls that must be carefully coordinated in order to stop the spread of the disease. It requires a comprehensive plan of action that includes human behavior and environmental controls. It also involves a rigorous cost-benefit analysis of the benefits that would come from stopping the transmission of the disease. These benefits are usually measured in terms of avoiding future infections and the associated costs of vaccination.
Before the advent of modern synthetic organic pesticides, humans and insects coexisted on a relatively level playing field. The number of insects in a given area tended to rise and fall with variations in the weather, interspecific competition, food availability and quality, and many other factors. The advent of modern pesticides meant that it became possible to eradicate certain pest populations from the earth. Suddenly people were no longer willing to tolerate worms in their apples or flies in their soup.
However, the use of pesticides can backfire. When an insect population is repeatedly exposed to a specific pesticide, the survivors may develop resistance. To prevent this, it is important to use multiple management techniques and to rotate the types of chemicals that are used.
Biological controls are often used in conjunction with other pest management strategies. Various strains of bacteria, fungi and viruses can be used to control pests. For example, the bacterium Bacillus thuringiensis produces a toxin that kills caterpillars but does not harm other plants or animals. It is available in several formulations that can be applied to weeds, trees and vines for effective control of many different types of pests.
In addition to reducing the use of toxic chemicals, biological control can be a more environmentally friendly way of managing pests. It can also be cheaper than chemical control. The key is to find the right biological organism that can attack and kill the unwanted pest.
