Pest Control involves attempting to reduce the number of pests to an acceptable level through prevention, suppression, and eradication strategies.
Prevention techniques aim to prevent pests from entering the premises. These can include sealing up holes and installing pest screens. Click Bed Bug Control Boise to learn more.
Pests are a nuisance and can cause damage to our property. They can also carry disease-causing microorganisms that can harm people and pets. The first step in solving any pest problem is prevention. Preventing pest problems is the easiest and most economical approach to pest control. It can be done by keeping buildings and their surrounding areas clean, removing food sources and water, and repairing structural damage that might attract pests.
All pests need food, water, and shelter to live and reproduce. Cluttered living spaces and untidy yards are like five-star resorts for pests. Cracks in walls, rips in screens, and loose door and window seals are their gateways into our homes. Regularly cleaning up trash, mowing and trimming grass, repairing leaky pipes, and fixing damaged fences prevent pests from entering buildings.
Store foods in sealed containers to protect them from pests. Eliminate outdoor food sources by keeping woodpiles away from houses, storing pet feed in tightly closed containers, and washing out empty milk jugs before placing them in the trash. Regularly cleaning counters and floors keeps them free of crumbs and spilled food.
Chemicals & insecticides are the most widely used method of controlling pests, but they should be used with care. They can be very toxic to humans and pets, especially small children. Always read and follow the label for instructions and potential hazards. Other non-toxic ways to control pests include physical methods (traps, screens, barriers and fencing) and environmental modification (cooler temperatures and humidity, modifying food and water availability).
Control measures should be selected that will reduce the number of pests to an acceptable level. This can be achieved by prevention, suppression or eradication. It is often difficult to decide how many pests are causing unacceptable harm and it may take time to determine the number of pests present, their damage and the costs of control. A pest should be controlled only when the cost of controlling it is less than the damage caused by the pest. Attempting to eradicate an entire population of pests is usually impossible and impractical.
Suppression
Whether the pests are in your garden, greenhouse or on your farm, you want to reduce their numbers so they do less damage. Usually, this is easier said than done. But there are methods to achieve it. The key is to use a control strategy that uses prevention and suppression techniques together, rather than using chemical controls in isolation. Preventive measures can help you keep pest populations below damaging or intolerable levels without the need for chemical control.
Preventive measures include biological control, habitat manipulation, cultural controls, and the use of resistant varieties. Biological control uses natural enemies – predators, parasites, nematodes, pathogens and competitors – to decrease pest populations. This method of control is inexpensive and environmentally friendly compared to the use of synthetic chemicals. It’s also effective.
Pests need food and shelter for survival. Providing habitat that’s useful to natural enemies will encourage them to live in and around your plants, keeping pest populations down. For example, if you plant flowers that caterpillars and other insects love to eat, those flowers will provide a constant source of food for the pests’ natural enemies.
Weather conditions can have a direct effect on the growth and activity of pests. For instance, a sudden rain or cool temperatures may slow down or suppress pests’ development and activity. Similarly, drought can increase pest problems by reducing the availability of their food.
Many pests are cyclical and will require control at regular intervals. Understanding pest occurrence and damage at different times of the year can help you synchronize your pesticide application with expected pest population increases or decreases. This “calender” approach can reduce the frequency of pesticide applications.
The way to keep a pest problem from getting out of hand is to regularly monitor pests and their damage and make changes to your management strategies as needed. Monitoring can be as simple as counting the number of pests or as complex as monitoring for signs of resistance to pesticides. The goal is to keep pest numbers below the Economic Injury Level (ETL) or, more accurately, the Control Action Threshold Level (CAT). This will allow you to use the least amount of pesticide with the best chance of preventing the pest from building up to unacceptable damage levels again in the future.
Eradication
Eradication of pests involves reducing the population to zero or below. This can be accomplished through a variety of methods including biological control, chemical treatment and trapping. It is important that all control measures used in eradication are designed to be as effective and safe as possible. For example, if you spray a pesticide inside your home, it is important that you follow the label instructions and safety warnings to minimise risk to yourself and others. It is also recommended that you thoroughly clean and remove food, cooking utensils, and other personal items from the area before spraying.
In a survey of New Zealand public attitudes to pest control, three characteristics were identified as being important to the general public: specificity (the ability to target the pest species intended); uncertainty (the degree to which a control method is understood and trusted to work); and humaneness (the extent to which a pest is killed without suffering). In order to maximise the effectiveness and reduce the risk associated with an eradication approach, it is critical that all steps are taken to ensure that the pest species in question has been eliminated, and that the method employed is effective and appropriate for the situation.
Biological control methods utilise natural enemies to limit or destroy the population of the pest in question. These enemies include parasites, predators and pathogens. This type of pest control can be a very effective tool for eradication, but the process is often expensive and time-consuming, and there is a lag between introducing the enemy species and achieving satisfactory results.
Chemical pesticides are chemical substances that poison or kill the target pest. They can be applied to crops in order to protect them from insects, fungi and weeds, or they can be used in the home to kill ants, cockroaches and other household pests. They are most effective when they are used in conjunction with physical traps and baits.
Integrated pest management is an environmentally sound and cost-effective way to manage pests in agricultural production, food processing, and residential areas. IPM relies on a combination of biological, cultural, and chemical control techniques to manage pest populations with minimal disruption to the surrounding environment.
Monitoring
Pests can damage or contaminate food and cause respiratory and other health problems in people, pets and livestock. They can also cause structural damage and aggravate allergies and asthma. Pest control is a complex endeavor that includes prevention, suppression and elimination. It is important to monitor pest populations and their conducive conditions as part of an integrated pest management (IPM) program. Monitoring provides an early warning system and helps determine when to begin control tactics.
IPM programs include a combination of biological, physical and chemical controls. Physical controls can include physical exclusion (screening, caulking and plastering) and trapping, and the use of repellents and pheromones to deter pests. Chemical controls can include pesticides and herbicides, fungicides and plant growth regulators. Biological controls, such as the use of beneficial organisms that can feed on or parasitize a pest, provide natural pest control without chemicals.
Monitoring can involve checking or scouting to find and identify pests, measuring their population levels, and assessing the level of damage they are causing. It can involve tracking environmental conditions, such as temperature and moisture levels, that can affect pest populations. It can also include determining if pests are at threshold levels, the point at which they require action to prevent unacceptable damage or contamination.
Threshold levels may be set by law or by standards for buildings, fields and crops. For example, food facilities may be required to take action against rodents, flies and cockroaches to prevent contaminating or damaging foodstuffs.
Monitoring can be time-consuming and requires a great deal of effort to collect, analyze and interpret data. However, it is a vital part of any effective pest control strategy. The information collected from monitoring can help determine when and how much pesticide or other control tactic should be used, and if the control measures are successful. Monitoring can also help identify and prioritize IPM maintenance tasks, such as repairing screens or caulking to prevent pests from entering the facility. It can also be useful in determining whether or not a food production site is meeting third party certification standards and regulatory compliance requirements.
