Pest Control Explained: Key Concepts 

Pest Control is the effort to keep pest numbers below harmful levels. Prevention is the most desirable method of pest control, but when that is not possible, Suppression and Eradication are options.

Pest Control

Physical methods include traps and barriers, and altering the environment such as removing weeds or water. Biological pest control uses natural enemies like parasites, predators and pathogens to reduce pest populations. Pheromones and juvenile hormones can also be used.

Pest control involves protecting the environment, human property and human life from unwanted pests. These include insects such as cockroaches, flies and ants that contaminate food and cause allergic reactions in humans; rodents like mice and rats that destroy furniture, damage homes and buildings and gnaw through electrical wiring; and weeds, fungus, grass and other plants that compete with crops and other desirable vegetation for soil nutrients. Pest control also includes the use of chemical pesticides to kill or repel these organisms.

Preventive pest control treatments prevent pest problems before they occur. During these treatments, professionals inspect the property for signs of pests and determine conditions that attract them. This includes removing sources of water and food, keeping trash cans tightly closed and disposing of them regularly, fixing leaky plumbing, and ensuring that the house or building is adequately insulated against the elements.

In addition to these preventive measures, a good commercial pest control program will also incorporate methods of controlling pests that have already become established. This may involve introducing more of the pests’ natural enemies, such as birds, amphibians, fish, reptiles, or other animals that prey on them; parasitic organisms; and pathogens that destroy them. This type of control is often referred to as biological or ecological pest control.

Integrated Pest Management is a method of pest control that combines preventive and suppression techniques to reduce the amount of pesticides used. It is often recommended by pest control companies because it is less hazardous to people, pets, and the environment than conventional pest control.

A key part of implementing IPM in food processing environments is developing a system of responsibilities for employees. Establishing what each person is responsible for and ensuring that they do it will help to prevent pest infestations. This might include determining who checks incoming shipments for pests, creating a protocol for how contaminated shipments are handled, and establishing sanitation and cleaning standards that will eliminate the need for pesticides. Employee training is important, as well. Educating employees on how their work impacts the prevention of pests will make them more likely to support and participate in a pest management program.

Suppression

The goal of pest control is to reduce the amount of damage done by pests, whether they are a nuisance or a threat. The primary method of pest control involves preventing them from occurring in the first place. This is done by making it difficult or impossible for them to find food, water or shelter. Often this is achieved by removing their preferred habitat. Another option is to use natural enemies to keep populations below harmful levels. This is one of the oldest forms of pest control.

The other main objective is suppression, which aims to reduce the number of pests to an acceptable level. This may be done by using chemicals or introducing natural predators to the environment. It may also be accomplished by using the physical attributes of a building or structure to make it unattractive or inhospitable to pests.

Pest control is a complex task that involves balancing the needs of people and the ecosystems in which they live. The actions of pests impact the health and welfare of humans, livestock, pets and wildlife as well as the quality of the environment in which they live.

For example, cockroaches and mice are pests that infest homes and cause asthma attacks in children and adults. Their body parts and droppings contaminate food, damage structures and create unpleasant environments. They also spread bacterial diseases like Plague, Lassa fever and Salmonellosis. In addition, their presence in residential areas increases the risk of fires.

There are many ways to reduce the pest population, including proper food handling and sanitation in stores, restaurants and food processing facilities. Foods should be stored in sealed containers and kept away from open sources of moisture. The use of fly and insect screens is also helpful. These should be used in accordance with local, state and federal regulations.

Preventing the emergence of pests should be the priority in any business that produces, processes or prepares foods. Factory managers should implement and observe good GMP (Good Manufacturing Practice) to prevent contamination from the emergence of insects, rodents and other organisms. All raw materials should be inspected, sampled and positively released before being introduced to production lines.

Eradication

The ultimate goal of pest control is to eradicate the organisms that cause harm, whether they are disease agents or plants. Eradication is difficult and costly. The benefits of eradication must be weighed against the costs to ensure that the program enhances human well-being rather than diminishing it. The long-term benefit of eradication is the dividend that is earned by avoided future infections and vaccination costs.

Infectious disease anthropologist Thomas Aiden Cockburn defines disease eradication as “the permanent reduction to zero worldwide incidence of a specific agent by deliberate intervention.” Eradicating a pest reduces the number of infected individuals, and thus the risk of infection (see diagram below). It also eliminates the need for vaccination, which is a costly activity that must continue as long as the pathogen exists in nature or in laboratories.

Eradication requires careful research into the biology of a pest and potential natural enemies. Suitable natural enemies are collected, quarantined to make sure they do not carry disease or parasites, and released in a site where the target pest is abundant, with attention to proper timing in the enemy and pest life cycles. Biological controls require repeated applications and regular monitoring.

Other pest-control techniques may be used in combination with the biological control process to improve the effectiveness of the approach. This includes pest identification, the use of pesticides that have a lower impact on non-target species and alternating the application of pesticides to help prevent selection for resistance.

The success of a pest control strategy can be assessed through the concept of thresholds. Thresholds are the numbers of pests that must be eliminated or reduced to an acceptable level for a given area or situation. The concept of thresholds is often a more practical goal than eradication in outdoor pest situations, where prevention and suppression are generally the goals.

For example, many noxious weeds are a significant economic and environmental threat to agriculture and natural areas. Their large numbers taint crops and wildlands, displace native plant species, and suffocate wildlife habitat. The Sutter County Pest Eradication Program targets these invasive plants to protect local agriculture, wildlife and ecosystems.

Treatment

In pest control, treatment refers to methods used to eliminate infestations of unwanted organisms. These can include removing food, water and shelter from a location where a pest is found, blocking entrance points or applying chemicals to kill them. Different kinds of pests require different treatments, and a company that offers pest control services usually has a range of methods to choose from. They may also offer advice on how to prevent pests from returning once they have been removed.

Many pests are found in residential and commercial areas, and some can cause significant damage. For example, the common clothes moth (Tineola bisselliella) and the case-bearing clothes moth (Tinea pellionella) can do a great deal of damage to natural fibres in clothing and carpets. The moths lay their eggs in these materials, and the larvae then feed on them until they are mature enough to fly away. The damage can be quite extensive, destroying valuable woollen clothes and furnishing.

Pests can also be a threat to human health. They can spread diseases and contaminate food and water supplies. In addition, they can disrupt ecological balance by replacing native species with invasive species that compete for resources with humans and other organisms. Pest control measures aim to protect human health, safeguard agriculture and food supplies, preserve property, and reduce environmental damage.

Eradication is a rare goal in outdoor pest control. It is usually more practical to focus on prevention and suppression, especially in areas with high levels of human activity. However, some eradication programs are supported by governments, such as the Mediterranean fruit fly, gypsy moth and fire ant control programs.

A variety of sanitation practices can help prevent or suppress pests, such as storing foods in sealed containers and removing garbage regularly. Good sanitation also includes using clean seeds or transplants and removing crop residue from fields. It can also involve preventing carryover of pests between seasons by avoiding the movement of crops, animals or equipment between locations.

Some pests can be controlled by other organisms in the environment, including parasites, predators and pathogens. These are often called biological control and can be supplemented by artificial controls such as pheromones and juvenile hormones.
