Natural forces, such as climate, natural enemies, and the availability of food and water, affect pest populations. Features like mountains and rivers restrict the movement of some pests.
Pathogens, such as bacteria, fungi, and protozoans, naturally reduce the growth rate of some insect pests. Nematodes, such as the cockroach-eating nematode Steinernema carpocapsae, act similarly.
Prevention
The most effective approach to pest control is preventive, avoiding infestations in the first place. It is also the most environmentally friendly.
The primary method of prevention is sanitation, cleaning up trash, spills, and crumbs to deny food, shelter, and water to pests. It is also important to keep grass and weeds away from buildings to eliminate easy access points for pests. Keeping trash receptacles tightly closed and making sure to know your local garbage collection day also helps to deny pests hiding places.
Another method of prevention is excluding pests from areas by sealing and caulking entry points, such as cracks and crevices around windows and doors. Installing screens on all windows and doors provides additional protection, as well as insulation. Thoroughly cleaning seldom used storage areas several times a year and vacuuming under furniture can help reduce the number of pests attracted to these spaces.
Physical pest control methods include traps and bait stations, which are effective for catching and killing pests. In addition, physical pest control can also include soil treatments to deter insects and rodents by reducing the nutrient content of the ground. For example, applying the helpful nematode species Steinernema carpocapsae to the soil can help suppress populations of cockroaches and grubs.
Predation, or parasity pest control, is another useful way to reduce the population of a targeted pest. Parasitic nematodes are microscopic worms that kill and feed on pests such as roaches, grubs, fleas, aphids, and caterpillars. They can be sprayed at the site or placed in bait stations to target these pests and are typically more environmentally-friendly than using toxic insecticides.
Threshold-based decision-making, part of IPM, involves assessing the environment and selecting the most appropriate treatment for each situation. For example, a few flies or house centipede sightings may not warrant treating, but seeing them every day may indicate that they are becoming a problem and need to be addressed.
It is important to communicate clearly with the Pest Management Professional (PCO) about the time and location of each sighting or indicator. This will help the PCO to identify the pest and tailor the treatment specifically for that pest, reducing the chance of off-target impact. It is also important to follow the product label instructions to maximize effectiveness and minimize risk.
Suppression
Pests can cause damage to living or working spaces, contaminate food, and spoil possessions. They can also spread diseases and threaten public health. Control of pests is therefore a vital concern for human populations. There are many methods of pest control, ranging from physical barriers to chemical controls. Different methods are more suitable for different pests. The first step in controlling pests is to prevent them from entering the environment in the first place. This can be done by removing their sources of food and shelter. For example, it is important to store foodstuffs in sealed containers and to keep garbage cans tightly lidded. Regular removal of trash and fixing leaky plumbing can also help to reduce the number of pests in an area.
If prevention is unsuccessful, the next step is to suppress pests once they are present. It is important to use only the minimum amount of pesticide necessary and to apply it in a way that minimizes risks to humans, pets, beneficial insects, and other organisms. Only trained and qualified specialists should handle or apply pesticides. Pesticides should always be used as a last resort, and they should be applied only when monitoring indicates that control is needed.
Suppressing pests requires knowledge of the pest, its biology, and its environmental factors. Monitoring usually involves examining a field, landscape, building or forest and determining whether or not the pests are at damaging levels. This information helps to decide whether to start control efforts and, if so, what management methods are most appropriate.
Some pests are controlled naturally by their natural enemies, including predators, parasitoids, and pathogens. The presence of these natural control agents limits pest population growth and can sometimes be used as a substitute for other control measures. Biological control is a major component of integrated pest management (IPM).
Physical or mechanical means of controlling pests include traps, screens, walls, fences and other devices that physically block pests from entry into an area. Heat, radiation, and electricity may also be used to alter the environment in a way that suppresses or eradicates pests.
Eradication
The goal of pest control is not to eradicate all pests. It is to eliminate those that pose a risk to health and safety, such as rodents, birds and insects. Rodents tend to be what most people think of when they hear the word pest, but ants and cockroaches can also cause problems in food or catering businesses. Birds, pigeons, and seagulls can pose health risks in large numbers and may need to be controlled as well. Likewise, insects such as cluster flies and bed bugs can cause significant damage to a home or business.
Eradication requires a comprehensive approach to preventing recurrence, including the identification of all possible sources of the disease and rigorous environmental controls. The World Health Organization (WHO) defines eradication as reducing the prevalence of a disease to zero in endemic areas. This can only be achieved by lowering the reproduction rate of the microbe to below its environmental threshold and controlling all reservoirs.
A major challenge is to ensure that interventions do not alter the natural ecology of the disease, which is influenced by population density of vectors, intermediary hosts and humans as well as by many other environmental factors that are highly variable worldwide. This is accomplished by monitoring and verifying that the reproduction rate is below its environmental threshold for a defined period. This verification must be carried out by independent, respected parties on a global scale.
Another way to achieve eradication is to introduce natural predators to the environment. This is one of the oldest forms of pest control and involves introducing a species that naturally preys on the pest in order to reduce their population. This is an effective strategy in rural tropical areas where the emergence of a new parasite that is resistant to insecticides is unlikely.
The use of biological pest control methods has become increasingly important as more and more chemicals are used up and resistance develops. Some examples of this type of pest control are the introduction of nematodes into soil to eat grubs and other insects that damage crops. These microscopic worms are very effective against a variety of insect pests, and a number of different species exist, including the roach-eating nematode Steinernema carpocapsae, which can be sprayed by the million and offers excellent control of cockroaches as well as a range of other insects.
Biological Control
The practice of using natural enemies (predators, parasitoids, and pathogens) to suppress pest populations is known as biological control. This can be done either by introducing one or a group of natural enemy species to a crop from their native ranges for permanent establishment (classical biological control) or by mass-rearing and periodically releasing augmentative biological control agents to temporarily increase their population density in an effort to quickly suppress a pest outbreak (additional biocontrol).
Prevention involves intercepting the pest before it reaches damaging levels and is most effective when based on good pest identification, monitoring practices, and knowledge of the life cycle of the target pest. It can also be aided by delaying pest management actions until the critical phase of the pest life cycle, such as bud burst or flowering, has passed.
A fortuitous form of biological control is the occurrence of native natural enemies that have accidentally arrived at an invasive exotic pest site and control it without any human intervention. Such natural enemies may be introduced deliberately to enhance their impact on an invasive pest, or they may have simply been released to the site and gained a foothold there.
Biological controls are generally more expensive than chemical treatments but are usually safer for the environment, crop, and human beings. However, they are prone to less consistency than many chemical treatments and require specific environmental conditions in order to thrive. Their manufacture and formulation must also take into consideration the fact that they are sensitive to climatic conditions, so that changes in weather patterns do not compromise their effectiveness.
Another potential limitation of biological control is that the majority of biocontrol organisms are host-specific. As such, the use of biological control is typically limited to only a few pests and requires that growers correctly identify pests. This is a serious issue, as the introduction of natural enemies to a new region requires that the species are tested for their ability to survive in the local habitat and adapt to its food source.
Biological control methods can be divided into four main categories depending on whether resident biocontrol organisms are stimulated with or without targeted human intervention (conservation and natural biological control, respectively) or agents are added for permanent or temporary establishment (classical and augmentative biological control, respectively). Clear definition of these terms will facilitate efficient regulation and application of this important pest suppression technique.
