The Basics of Pest Control

Pest Control Nampa includes preventive and curative techniques. Preventive measures include removing food and water sources, fixing leaks and caulking cracks.

Clutter provides places for pests to breed and hide. Regularly removing garbage and closing off access to food, water and shelter helps keep pest numbers below damaging levels.

Natural enemies such as parasitoids and predators can be introduced to control pests. Juvenile hormones can also be used to control pest populations by keeping them from developing into normal adults.

Prevention

Pest control focuses on preventing pest infestations rather than treating them once they are already present. Prevention is the most cost-effective of all pest control methods. It involves creating an environment that is less conducive to pests by addressing factors such as food, water and shelter. This approach is often part of Integrated Pest Management (IPM), which is a comprehensive strategy that uses several tactics to manage pests. Prevention techniques can include cultural practices, sanitation and cleaning, physical barriers, pest monitoring and chemical treatments.

Some pests are merely a nuisance, while others are a serious health and safety risk, like cockroaches, rodents and fleas. Some cause property damage, such as termites, ants and wood-boring bees. Others spread diseases, such as rabies and salmonellosis, or trigger allergies, such as stinging insects and venomous spiders. Uncontrolled pest populations can damage buildings, furniture, garden and personal items, degrading their value and appearance.

Pests may be repelled by physical barriers, such as fences, netting and door sweeps. Chemical barriers include pesticides, insect repellants and baits. Biological controls are also helpful. These may be anything from natural predators or parasites to soil microbes.

In commercial settings, preventive pest control strategies focus on preventing pests from entering the building or gaining access to the food supply, water and other resources inside. These strategies can include inspecting incoming products for signs of pests, designing work areas to discourage pests, implementing a uniform cleaning protocol and training employees to spot and report suspicious activity.

Pest prevention services can help home and business owners protect their investment by reducing the need for costly repairs or replacements caused by pests. Routine treatment can also give homeowners peace of mind, knowing that professional services are taking care of pests before they have a chance to damage the home and/or family. For businesses, a pest prevention program can protect brand reputation and customer loyalty by eliminating the negative impression of a pest infestation. It can also increase productivity by allowing workers to focus on their jobs without interruption from unwanted pests. For both, preventive pest control is an essential service that should be included in the pest management plan.

Suppression

Suppression is the action of controlling a pest population below levels that cause unacceptable damage or injury. The action taken to achieve suppression may be prevention, eradication or control, depending on esthetic, health or economic considerations. Thresholds, which represent the action level that requires a pest control response, have been determined for many pest species, and vary among horticulture, agriculture and livestock.

Several methods can be used to suppress pest populations, including cultural controls, biological controls and chemical controls. Biological controls involve using a pest’s natural enemies — predators, parasites and pathogens — to reduce its numbers or eliminate it entirely. This includes the use of pheromones to attract and confuse males, preventing them from mating with females and thus lowering their numbers, and the application of juvenile hormones to prevent pests from maturing into adults.

Chemical controls include fungicides, herbicides and insecticides. When pesticides are used, they must be applied consistently and at a rate that will suppress the population to the desired level without harming beneficial organisms. Otherwise, the population will quickly repopulate and eventually outgrow the desired level of control. Using different chemicals to control the same pest or applying them at intervals can help minimize the development of resistance.

In addition to these conventional approaches, research is underway to increase the effectiveness of plant-based methods of pest control. For example, plants that produce pheromones to attract and repel insects can be cultivated to provide a natural control. Pheromones are also useful in monitoring pest populations, as they can be captured and analyzed to determine the level of a pest population.

In another approach, the conservation of beneficial insects can be promoted in cropping systems to naturally suppress pests. This is known as conservation biological control and can reduce the need for insecticides, saving $4.5 billion a year in US agricultural costs. Wildflower strips sown at the edges of fields or in crop rows can enhance this natural process, as well. The composition of these mixtures can be designed to showcase a range of traits that benefit the regulation of pests, such as a mix of foraging and ground-foraging species that compete with each other to attract and eat pests.

Eradication

The last option, eradication, involves eliminating an invasive species from a region to the point that recolonization is unlikely. This is a rare goal in outdoor pest situations, where the goal is usually prevention or suppression. However, it is common in enclosed spaces such as greenhouses and other man-made environments.

For example, Washington entomologists stamped out the citrus longhorned beetle, which has spread in nurseries throughout the state, by using quarantines, tree removal and mating disruption techniques. In California, a similar strategy helped eradicate the European grapevine moth, which arrived in wine country in 2006 and destroyed tens of thousands of acres of vines.

But eradicating these pests is no easy feat. They breed quickly, policies often slow down response times, and funding is limited. And even if authorities act fast, it may take decades before the pest is fully eliminated.

To better understand why some eradications succeed while others fail, researchers have collated data on 173 eradication campaigns against invertebrate plant pests, plant pathogens (viruses/viroids, bacteria and fungi) and weeds from across the world. They compiled a classification tree and found that the probability of success depends largely on whether the action is launched before the population reaches a critical threshold, the extent to which the infestation has been introduced, how quickly the reaction is initiated, and the extent to which sanitary measures are applied.

In addition, if the pest is being introduced for agriculture or forestry and has not yet escaped from cultivation, eradication will be more likely than if it is being introduced for other purposes such as gardening or foraging and has been in the area for a long time. But the results also show that, regardless of the pest type or the habitat in which it has been introduced, a molecular approach to defining eradication units will greatly improve the probability of success for any eradication campaign.

The classification tree also shows that eradication is more likely in man-made habitats than in natural ones, and that it is more likely to be successful at local or international scales than at regional or national ones. This is especially true in Australasia, where eradication campaigns have been more successful than in the Americas and Europe, which have seen more failures.

Monitoring

Pest control begins with monitoring, which includes both inspections and trapping. Monitoring allows you to determine when to take action against pests. This is important because pest populations vary between fields, buildings, and even from year to year. Therefore, it is critical to have an integrated approach that is site, crop, and pest-specific.

One of the simplest methods of pest monitoring is visual observation, in which the presence of pests such as aphids and spider mites is determined by looking for them on leaves, stems, or other plant parts. This method is best suited for pests that are difficult to detect without close examination, such as aphids and spider Mites, or that do not fly readily when disturbed, such as the immature stages of some psyllids.

Another type of monitoring is trapping, in which pests are captured on the surface of baits, usually made of a substance such as pheromones or chemicals that mimic the scents of other pests. Various types of traps are available to monitor pests in different settings, including soil, field, and food processing facilities. Traps can be used to monitor the number of pests present, as well as their locations within a facility or field.

In addition to pest traps, other tools used for monitoring include phenology calendars and degree-day models. These are knowledge based models that help IPM practitioners understand the relationships between periodic biological events and seasonal climate changes, rather than relying solely on calendar dates for monitoring and timing of control tactics.

When using pest traps in a food processing facility, it is crucial to maintain a clean environment, as pests may hide in dark harborages such as corners or crevices. A flashlight is helpful to illuminate these areas, and a log helps document the frequency of pest sightings in order to identify patterns in pest activity and locate problem areas within the facility. Also, hand tools like screwdrivers and pliers can be used to reinforce barriers or repair screens to reduce the chances of pest intrusion.

Prevention is a goal of all pest control strategies, and it is possible to prevent pests from damaging crops by making the environment unsuitable for them or by changing environmental factors that favor the crop over the pest. This type of prevention is the focus of Integrated Pest Management (IPM), which is an ecosystem-based strategy that promotes long-term preventive strategies such as cultural practices, habitat manipulation, and the use of resistant varieties. It is a balanced approach that reduces pesticide usage and minimizes risks to human health, beneficial organisms, and the environment.
