Pest control is the action or process of controlling a harmful species of insect, disease-causing pathogen, or other organism that damages plants or crops. Its three goals are prevention, suppression, and eradication. Contact Nature Shield Pest Solutions now!
Prevention strategies are designed to keep pests from gaining a foothold in the first place. This means removing their food sources, shelter, and other factors that attract them. Taking care of the environment around your home also helps. This includes sweeping and vacuuming to remove visible food particles and sticky residues, regularly removing trash, storing food in airtight containers and fixing leaky pipes to eliminate standing water where some pests like mosquitoes thrive. Maintaining the integrity of your landscaping is another important preventative measure. Keeping branches, shrubs and grasses trimmed away from the house will prevent rodents, spiders and insects from using them as highways to access your home. Sealing entry points such as cracks, crevices and loose screens will keep many pests out.
Predatory and parasitic organisms, such as birds, mammals, reptiles, fish, insects and mites, are often the best natural controls of pest populations. Some disease organisms, such as those that attack plant-feeding insects or fungi, may be controlled by the weather. Unusual weather patterns, such as rain, freezing temperatures or drought, can alter a pest population by killing or suppressing them.
Some pest control techniques, such as traps and baits, are more effective at reducing a pest infestation than spraying products. These methods also offer less risk of exposure to chemical products and can be combined for more effective results.
Spraying chemicals should only be used when necessary and always in conjunction with other pest management tactics. Pesticides can be dangerous and must be used according to the label’s instructions, avoiding direct contact with plants and people, and stored carefully to avoid accidental poisoning.
It’s important to realize that pests are part of a natural ecosystem, and even though they can be a nuisance, they play an essential role in food chain and habitat systems around the world. While it is important to minimise their impact on human activities, it is also vital to consider their role in a balanced ecosystem and be cautious of pushing for the total eradication of pests from the earth. This approach is known as Integrated Pest Management.
Suppression
Suppression strategies aim to reduce pest numbers to an acceptable level and cause as little harm as possible. A key concept in this strategy is to define “action thresholds.” These are the levels of pest damage that force action. Thresholds are often based on esthetic or health considerations, but can also be economic ones. For example, an unacceptable number of ants or rats in a kitchen may trigger control measures.
Some methods of suppressing pests are cultural, such as preparing soil; choosing plants that are well-suited to the site and less attractive to pests; interplanting; and timing planting dates to avoid peak insect or disease periods. Other methods are more direct, using predators, parasites, and pathogens that naturally occur in nature to control pest populations. For example, birds, reptiles, amphibians, fish, and mammals feed on some insects and help keep their populations in check. Fungi can also be effective in controlling insect and mite pests and, in some cases, vertebrate pests as well.
When pests do appear, scouting or trapping is important to determine the extent of the problem and how quickly it needs to be controlled. Weather conditions, especially temperature and humidity, affect pest activity as well. A sudden change in the environment can make a pest population explode or recede depending on the species and its host.
Most modern pesticides kill only those pests that are susceptible to the chemical. This is called selective killing. Unfortunately, resistant pests eventually develop, allowing them to survive and pass on their genes to future generations. To avoid this problem, control measures need to be integrated and used with caution.
The goal of conservation biological control is to attract and protect natural enemies so that they can effectively manage pests without the need for chemical intervention. Practices of this approach, which is also known as augmentation biological control, are available to homeowners and include placing traps for insects; removing debris that harbors pests; introducing new predators, parasitoids, or diseases into the landscape; and providing habitat for natural enemies. Another method that is rarely used but could be useful is to inject a beneficial organism into the soil to protect plants from pests. For example, boron (B) can be injected into the soil to kill self-grooming pests like aphids and psyllids.
Eradication
Pests can spread diseases, contaminate food, and damage property. They can also disrupt natural ecosystems and be a threat to human health. The goal of pest control is to eliminate or reduce the amount of pests in an area. Pest control methods include traps, baits, pheromones, fumigation and other chemical treatments. Pest control services may be offered by commercial or private companies. Most people think of pest control as eliminating unwanted creatures like rodents, cockroaches and termites, but pests can also include insects, weeds, plants and disease-causing microorganisms.
Eradication is a rare goal in outdoor pest situations, where the aim is usually prevention or suppression. However, eradication strategies can be successful in enclosed environments such as dwellings, schools and offices, hospitals, food processing plants and storage areas. Eradication is possible because pest populations are generally smaller and less mobile in closed spaces.
Achieving eradication requires the development of diagnostic tools that are sufficiently sensitive and specific to identify the pests, and sufficiently simple to be applied globally by laboratories with a wide range of capabilities and resources. It is also necessary to find ways to interrupt the pest’s life cycle in order to eradicate it, which involves eliminating its hosts and preventing the virus from being transmitted to new ones.
Another form of eradication is to change the environment in which a pest lives so that it becomes unsuitable for it. This can be done by introducing predators or parasites that will prey on the pest, or by altering the habitat so that it is not suitable for it. For example, nematodes (tiny worms that live in soil) can be used to kill off aphid infestations by attacking them and consuming their juices.
Chemicals are the most commonly used pest control agents, and they are typically very toxic. They are available in a variety of forms, including sprays and powders, and they may target different kinds of pests. Herbicides, for example, are used to kill weeds, while insecticides and fungicides are used to kill insects or plant pathogens. Only trained pest control professionals should use chemicals, as they can be dangerous if not used correctly.
Natural Forces
A variety of natural forces can help keep pest populations below damaging levels. These include predators, parasites, and disease organisms. Using natural methods is usually slower than using chemical pesticides, and they don’t always kill the entire population of target pests. But these methods are less likely to harm people, pets, or wildlife, and they can be environmentally friendly.
Predators are animals that hunt and kill other animals for food. They include birds, mammals, reptiles, and insects. Increasingly, growers and green industry professionals are using predatory insects, nematodes, and microbe-based solutions to manage pests on ornamental plants, turfgrasses, and fruits and vegetables. These methods are also becoming more popular with consumers worried about the negative health and environmental risks of chemical pesticides, such as neonicotinoids.
Parasites live on or in the body of another living thing, called a host, and get all of their nourishment from it. Examples include fleas, ticks, and mites. Disease organisms are fungi, bacteria, and viruses that attack or infect their hosts and cause them to become unhealthy or die. The most well-known example of a pathogen is the bacterium Bacillus thuringiensis (Bt), which produces a toxin that destroys the midgut of caterpillars and other Lepidopterans. Using Bt can be an effective and environmentally friendly way to control caterpillars in vegetable gardens.
The goal of eradication is to eliminate a pest from an area, but this is rarely a realistic option in outdoor pest management, where prevention and suppression are more common goals. However, eradication may be possible in enclosed environments such as greenhouses, and it is often the goal of managing pests in agricultural crops.
Threshold-based decision making involves scouting and monitoring to determine whether or not pest numbers are above or below an acceptable level. Ideally, action should be taken only when the number of pests is above a threshold that can be tolerated without significant economic or aesthetic damage, and when the use of chemicals does not risk harming beneficial insects and other organisms. To minimize the amount of time and money spent on pest control, scouting and monitoring should be carried out regularly.
