Pest Control – The Basics of Prevention, Suppression, and Eradication

Pest Control Van Nuys strategy includes preventive methods to keep pests away, suppression to reduce the population to an acceptable level, and eradication when needed. It also requires proper application of any chemicals used and observance of local and state regulations.

Remove food sources that attract pests. For example, ripe fruit draws flies, and open trash containers attract rodents. Store grains and food in sealed containers.

Prevention is keeping pests from getting established in a site or environment. It involves assessing the site or environment to identify and remove things that make it attractive to pests, such as food, water, or shelter. This may include regular inspections and the use of exclusion techniques like sealing cracks and gaps in walls and foundations, maintaining good sanitation practices that reduce food sources for pests, and implementing barriers to pest entry such as screens on doors and windows.

Pests can be dangerous to people in many ways, including disease, discomfort, and even death. They can also damage property and contaminate food. Pests such as rodents can chew through drywall and wooden structures, leaving them unsafe, and cause electrical fires by gnawing through wires. Other pests such as cockroaches, fleas, and ants can carry diseases, contaminate food, or worsen asthma and other respiratory conditions.

There are three goals in pest control: prevention, suppression, and eradication. Prevention is the most desirable goal in outdoor situations because it is the best way to protect health and property. However, in some cases, pests must be controlled to a level that is acceptable such as the Mediterranean fruit fly and gypsy moth control programs. Eradication is possible in indoor settings because there are usually fewer environments that promote their growth, and control is easier since the environment is less complex.

Properly identifying pests is important to understanding the role they play in the ecosystem and determining the best management strategy. For example, knowing a pest’s lifespan and life cycle helps when setting baits and traps. For example, knowing that Japanese beetles are in the egg, nymph, and pupa stages allows you to choose the right time to set traps so that the beetles will be trapped when they are most vulnerable and not just after they have matured into adults and moved on. Correctly identifying pests will also help when scouting and monitoring for them. It is helpful to be able to recognize how many pests are present and at what stage of development so that you can decide when it’s necessary to take action, such as spraying for Japanese beetles with insecticide.

Suppression

The primary goal of suppression is to reduce the pest population below harmful levels. This can be achieved by a variety of methods. The most effective methods reduce the availability of food or shelter for the pest. Chemicals may be used to kill or repel the pest. Resistant varieties of crops, wood, or animals may be used to prevent the spread of a pest. Cultural practices change the environment, condition of the host plant, or behavior of the pest to prevent the infestation.

Sanitation practices reduce pest populations by removing their food and shelter. These include using pest-free seeds and transplants, preventing weeds from reproducing, irrigating to avoid situations conducive to disease development, cleaning tillage equipment between fields or locations, and eliminating alternate hosts or sites for the pest organisms.

Natural enemies (predators, parasitoids and pathogens) are effective at suppressing pests without the use of chemicals or other human intervention. Biodiversity in these enemies can increase the efficiency of the suppression process. For example, species richness can improve prey-predator relationships through complementarity (e.g., day versus night foraging species; Chalcraft and Resetarits 2003), or interference (e.g., large vs. small species; Losey and Denno 1998).

Biological control techniques involve the introduction of microorganisms or plants that can suppress pests. These can be introduced by planting them in the field or by introducing them to the habitat in which pests occur. Biological controls can be extremely efficient at controlling some pests, particularly plant diseases.

Chemical controls, such as the application of insecticides, herbicides or fungicides, are used to reduce pest numbers. These methods, however, can cause harm to the living and nonliving surroundings of the treatment area, may affect other pests or even non-target organisms, and are not always effective. In addition, they can create resistance among pest populations, which is the primary challenge to their continued use.

Integrated Pest Management is the practice of using all available tactics to prevent pest infestations and reduce the damage they cause. It involves combining prevention and suppression strategies with cultural, biological, and chemical approaches to reducing pests to acceptable levels. It is a more sustainable approach than relying solely on the use of chemical pesticides.

Eradication

Unlike suppression and prevention, eradication aims to remove an organism from the environment completely so that recolonization is not possible. It can be a difficult goal to achieve. However, it is often the most desirable approach for certain pests in enclosed environments such as dwellings; schools, offices and other public buildings; health care, food processing and preparation facilities; and cultivated plants used in greenhouses, orchards and fields.

The eradication process typically involves three main activities: surveillance, containment, and treatment or control measures. The NPPO responsible for the eradication programme should establish criteria to determine when the absence of the pest can be declared, and it is important that proper documentation and process controls are in place to provide confidence in the results. It may also be necessary to consult with NPPOs of importing countries over some aspects of the eradication process.

2.3.1 Initial investigation

A comprehensive initial investigation of a newly-detected pest should be conducted to assess its impact and the need for eradication action. Among other things, this should include an examination of the ecological and biological factors that will influence the effectiveness of any intervention tools developed, as well as information about the geographical origins and pathways for reintroduction. This can be done using the framework of a pest risk analysis (PRA) as described in ISPM 2 and ISPM 11.

2.4.2 Conclusion: Once the need for eradication has been established, a cost-benefit analysis should be undertaken. This should consider the potential economic impacts of a successful eradication program and the implications of an unsuccessful one. The results of this analysis should be made available to NPPOs and to other stakeholders. Depending on the outcome of the cost-benefit analysis, consideration should be given to whether to abandon the eradication program and adopt a pest management strategy instead. The decision to abandon a successful eradication program should be taken only after careful evaluation and discussion. This should include an evaluation of the reasons for failure, including any new knowledge that has been gained since the program began. NPPOs should also review the need for an ongoing eradication program on a regular basis to ensure that it is appropriate.

IPM

Integrated pest management (IPM) is an effective approach to managing all types of pests in urban, agricultural, and wildland/natural areas. It is a science-based decision-making process that integrates biological, cultural, physical, and chemical tools to manage pests in ways that minimize economic costs and risks to people and the environment.

IPM is the middle ground between not managing pests at all and widespread use of any type of pest control, regardless of the pest population or risks to other plants, people, and animals. It requires a detailed analysis of the pests, the damage they cause, and how to reduce their numbers to an acceptable level.

Pests can be insects, diseases, weeds, or other organisms that harm crops, trees, or shrubs. They attack from all sides, chewing or sucking out plant juices; spoiling seeds and berries; destroying leaves, fruit, and roots; and spreading disease. There are many kinds of pesticides to kill or repel them, including herbicides, fungicides, insecticides, rodenticides, nematodes, and larvicides.

UC IPM provides comprehensive information, tools, and publications to help growers develop successful, long-term pest management programs. The basic strategy is to prevent or deter pests from damaging a crop by creating conditions that are unfavorable for them. This can include planting crops that are tolerant to common problems, altering planting times or spacing to discourage diseases, and using disease-resistant varieties. It also can include attracting beneficial insects, trapping, and monitoring.

The first step in IPM is to monitor a landscape or garden on a regular basis and make notes of the health of plants and any insect activity. Accurately identifying the pest and the problem plant is crucial because this will determine whether or not any treatment is necessary. If treatment is deemed necessary, the first step is to try less risky options like physical or biological controls before moving on to more aggressive chemicals. This will be followed by monitoring and evaluating the effectiveness of these treatments. The final step is to apply the most appropriate treatment, always following the label directions for application amounts and timing. This will ensure that only the amount of pesticide needed is applied, reducing environmental and human exposure.
