Pest Control Methods
A pest is any organism that causes economic or environmental damage. Pest Control Tarzana methods include prevention, suppression and eradication.
Proper identification is the first step in any pest management program. This enables you to determine basic information about the pest, such as its life cycle and the time when it is most susceptible to control measures.
Pest identification is the first step in developing an effective pest control strategy. Incorrect identification of a pest can lead to the use of incorrect treatment methods. It is also important to understand the pest’s biology and life cycle in order to predict when it will reach the highest pesticide risk.
Many pests undergo a significant change in appearance during their development and may look quite different from the adult form. For example, a weed seedling often looks very different from the mature plant. Many insect pest species exhibit different behavioral characteristics during their lives as they move between developmental stages. The timing of these transitions is important in determining when to treat the pest for maximum efficacy.
A common mistake in pest identification is to confuse different forms of a single species. This can be especially difficult when different species of insects have similar appearances, such as caterpillars, aphids and leafminers. A mistake in this regard can be very costly.
Species identification is particularly crucial when considering the use of biological controls or other integrated pest management (IPM) strategies. IPM is an ecosystem-based approach to pest control that incorporates several techniques such as modification of cultural practices, introduction of beneficial organisms and the use of resistant varieties. IPM strategies are based on monitoring and are designed to reduce the need for chemical intervention. Chemical treatments are used only when the monitoring results indicate they are needed according to established guidelines. Moreover, all pesticides are applied with the objective of removing only the target organism while minimizing risk to non-target plants and animals.
Incorrect pest identification can also result in the use of inappropriate treatment methods, or even the wrong type of chemical. This can be a serious problem for growers using IPM because it can render the IPM plan ineffective or even cause damage.
It is a good idea to keep an IPM toolkit in the field for insect scouting, including a flashlight, silicone caulk and caulk gun, a flyswatter, mouse snap traps, sticky tape for crawling insects, and a collection of labelled digital images from your computer. In addition, local Land Grant University extension services and IPM programs often offer a variety of publications and fact sheets that contain guidelines for insect scouting and identification.
Prevention
Pests are a nuisance and can cause damage to property, but there are ways to keep them from showing up. Preventive pest control includes preventing pests from entering the premises, removing conditions that are conducive to their survival and reproduction, and identifying and controlling factors that attract them. This is more effective than reacting to an infestation after it occurs.
Preventive pest control techniques can be used in both indoor and outdoor areas. In outdoor settings, this usually means reducing the availability of food, water and shelter to pests. This is best achieved through regularly cleaning the grounds, maintaining good sanitation practices and establishing barriers to entry, such as caulking cracks and crevices around baseboards and doors.
In some situations, eradication is the goal, but this is rare in outdoor pest management because of the difficulty of completely removing a pest once it has become established. In enclosed environments, eradication is more common and may be achievable with proper controls and monitoring.
Clutter provides places for pests to breed and hide, so clean up clutter in and around the home and place garbage in tightly-closed containers. Caulk cracks and crevices, fill spaces with steel wool and keep trees and bushes away from the house to prevent pests from nesting there. Regularly sweep and vacuum the floors to remove dirt and debris that can harbor germs and odors, which attract pests.
Eliminating a food source is important in any pest prevention plan, and this can be done by keeping food in sealed containers and trash in tightly-covered dumpsters. Many pests also have strong olfactory senses, so be sure to eliminate odors by burning or washing any items that may contain a scent, including clothes and dishes.
Natural enemies, such as predators and parasites, can be used to control some pests. This is called biological pest control and typically requires a period of time for the natural enemies to establish themselves in an area and reduce the pest population below economic damage levels.
Taking a proactive approach to pest control is a smart idea for anyone, especially those with indoor spaces such as restaurants and retail stores. Customers are less likely to return if they see pests in the establishment, and this can quickly lead to a loss of revenue. By following basic prevention tips and working with a qualified pest control company, you can keep pests out for good.
Suppression
Pests can cause damage and loss of value to plants, crops, livestock, structures, and the environment. The goal of suppression is to reduce the population of a pest to a level that causes no unacceptable harm. Suppression is often a component of preventive pest control, because pests can be more difficult to control once they have established themselves in a field or a home.
Suppression of a pest population may be accomplished using natural enemies, cultural techniques, physical controls, or chemical controls. The choice of control method depends on the type of pest, its impact on humans and the environment, and the availability of alternatives. The use of biological agents should always be used in conjunction with other control measures to increase the probability of success and decrease the risk of exposure to beneficial organisms and nontarget species.
Climate, natural barriers, and the availability of food and water determine the population levels of many pests. For example, high mountain ranges limit the movement of some insect pests, and large bodies of water restrict the distribution of others. The availability of shelter and overwintering sites also influences pest populations.
In the field, scouting and monitoring can help determine the extent of a pest problem. Preventive tactics, such as crop rotation and soil conditioning, can minimize the need for pesticides.
In homes, good housekeeping, garbage disposal and sanitation practices can help limit the number of pests. Food products should be stored in tightly closed containers, and garbage should be disposed of regularly. Insect droppings and body parts can contaminate foodstuffs, and they can carry disease-causing microorganisms that can infect people who consume the contaminated food.
In food processing environments, pests are attracted mainly to water and food, but they can also cause contamination with disease-causing microorganisms in their intestinal tracts or on their external surfaces, physical damage to equipment and materials, and deterioration of the finished product. Food manufacturers must implement strict GMPs, good housekeeping and waste management to ensure that the plant does not become a source of pests. In addition, regular scouting should be conducted to identify related pest species and their densities in the facility.
Eradication
Pest management aims to eliminate or control the pest population within an area or geographic region. There are four main methods for managing pests: eradication, suppression, containment and prevention (Food and Agriculture Organization, 2005). Eradication is the ultimate goal in some situations where an organism poses a threat to the economic or environmental sustainability of an area. The other three methods, prevention, containment and suppression, are merely tools used to achieve this end.
Eradication is a difficult goal to accomplish and requires a multi-faceted approach involving many stakeholders, including government agencies, industry groups, land managers, local communities, and citizens. It can be particularly challenging in urban areas, where a number of factors, such as the presence of other species or human activities, can interfere with the success of an eradication campaign. In these situations, the eradication strategy often involves the use of biological controls and other measures that are less likely to impact on other species or humans than chemical controls.
An eradication is a major undertaking and has a significant financial cost, and therefore requires political and social support. It is also a long-term commitment, with verification that the organism has been eradicated required on a global basis. The difficulty of achieving this is one reason that eradications are rare goals in outdoor pest situations, and most focus on prevention and suppression.
The likelihood of eradicating an invasive species depends on a range of factors, and the most important are probably the taxonomic Kingdoms of the organism, the reaction time between detection of the pest and the start of the eradication effort, the spatial extent of the infestation, and the level of biological knowledge and preparedness of the country in which the eradication is taking place. In this dataset, the optimal boosted tree (Figure 2) shows partial dependence plots for these predictors.
Overall, eradication campaigns were more successful in man-made habitats than in (semi)-natural ones, and more likely to succeed if they were initiated early, for plants that had escaped cultivation as ornamentals rather than wild plants, and at the local or international scale rather than the national or regional levels. The probability of eradicating a pest increases as the residence time in a given site decreases, but it does not appear to play an important role in relatively new invasions.
