What is Pest Management?

Pest Control Stuart is the process of managing pests so they cause as little damage as possible. It involves inspections to identify entry points and influences that may attract or promote pests.

Natural, biological, chemical, and cultural controls can all be used to manage pests. For example, aggregation pheromones from prey can be used to regulate Lepidopteran pests (butterflies and moths). The use of microorganisms can also control pest populations by degrading or limiting the availability of key nutrients.

Preventive Pest Control is an ongoing effort to keep pests away from homes, preserving property value and keeping families safe. It involves regular inspections and treatment to identify and treat conditions that lead to pest infestations before they happen. Preventive pest control is much easier and less expensive than one-off treatments to combat an already established problem, saving homeowners time and money. It also helps to preserve and maintain the value of a home, since frequent pest treatments prevent the need for costly repairs.

Pests are organisms (insects, fungi, rodents, vertebrates, plants, bacteria, viruses, or weeds) that negatively affect human health and economic or natural resources. They can damage or devalue agricultural crops, food stores, structures, lawns and gardens, and displace native species. In addition, they can cause disease in humans and pets through their faeces, saliva, droppings or bites, and can trigger existing medical conditions like asthma.

Integrated pest management is the preferred approach to managing pests because it uses a series of economical and environmentally responsible strategies to reduce or eliminate pest populations. Prevention methods include establishing a regular inspection routine, correcting environmental factors that promote pest populations and restricting their growth through sanitation, exclusion, maintenance and cultural practices.

A good example of an effective preventive measure is to seal cracks and crevices where pests can enter. Another is to regularly clean areas where pests may breed and nest. This includes garbage bins and other trash containers, as well as eliminating standing water where mosquitoes can breed. Cultural practices can be as simple as rotating crop varieties or choosing plant varieties that are less prone to pest infestation.

Eliminating the conditions that encourage pests is the first step to controlling them. For example, reducing the number of open trash cans on your commercial property or changing your disposal method can help reduce rat infestations. In some cases, you can make your business more unattractive to pests by modifying the layout and appearance of your property or adjusting lighting. You can also install screens and traps to limit access and use pesticides to kill or repel pests, as needed.

Suppression

Suppression strategies reduce the risk of damage by keeping pest populations below damaging threshold levels. Often, this involves combining preventive techniques with one or more suppression tactics. It may also involve limiting the area where pest control measures are used in order to keep them from spreading beyond acceptable levels. Suppression methods include cultural practices, physical barriers, biological controls and pesticides.

In agricultural contexts, suppression techniques aim to deter pests and reduce their numbers to a level where their impact is acceptable. This is similar to controlling a weed in your garden–you don’t want it to take over your entire crop, so you pull some here and there and use a little mulch or targeted spray to keep it at bay.

Using pest management tools to keep pests below damaging thresholds can help farmers save money and avoid costly damage to their crops. Preventive measures include planting crop varieties that are less susceptible to pest infestation, locating fields away from areas known for having high pest pressure and planting perennial crops in locations where they can grow without being disturbed.

Controlling weeds and managing irrigation schedules can also deprive pests of a comfortable environment or make it more difficult for them to move between locations. Similarly, ensuring that greenhouses and other enclosed spaces are frequently cleaned and that tillage equipment is regularly sterilized can limit the spread of disease-causing pathogens.

The use of natural enemies, which are predators and parasites that kill or otherwise affect pest species, is another important tool in crop protection. In the United States alone, these natural enemies provide an essential ecosystem service valued at over $13 billion per year.

However, studies show that a landscape dominated by crop fields can decrease the abundance of these beneficial species and thus the strength of natural pest control. Therefore, it is important to maintain a good balance of croplands and non-crop habitats to ensure that the appropriate number and types of natural enemy guilds can be maintained in field cropping systems. Similarly, establishing buffer strips around crop fields or incorporating flowering crops into field margins can provide additional habitat for natural enemies and complement the effectiveness of biological control.

Eradication

When eradication is not possible because of cost or negative environmental impacts, pest populations must be suppressed. Suppression is achieved through chemical, biological or cultural means.

Early detection of pests is necessary to prevent damage, minimize pesticide use and maximize the effectiveness of control measures. This requires scouting or monitoring plants frequently, knowing the common pest species in the area and understanding their biology.

Some pest control is biological, using organisms that naturally prey on or parasitize the pests. This can include the release of natural enemies such as predatory insects and pathogens such as fungi. In addition to being safe for the environment and humans, biological controls can also be economical and easy to use.

Biological control may be combined with other management options to form an Integrated Pest Management (IPM) plan. IPM is an alternative to a pure chemical approach and takes the ecosystem as a whole into consideration. It utilizes a combination of prevention, suppression and eradication methods to produce the best results with the least amount of follow-up maintenance.

Chemical pest control includes the use of specific substances, often referred to as pesticides, that are applied directly to the pest or their food source to kill them or interfere with their life cycle. These chemicals can be broad-spectrum or narrow-spectrum and organic or inorganic. They are usually grouped into categories such as herbicides, insecticides, rodenticides, fungicides and larvicides. They are carefully studied and tested for safety before being approved for use in the United States under federal, state and local laws.

Invasive species such as Mediterranean fruit flies can cause severe economic problems by shutting countries out of the international export market if they cannot meet strict pest-free requirements. Eradication treatment is expensive, but it can be successful. The IPM technique for eradicating these flies involves placing gel-like bait stations on utility poles and in public right-of-way trees that contain a male attractant and a small amount of an insecticide. When the males are killed, the females cannot breed and their numbers dwindle.

Eradication is most likely the goal of pest control in enclosed areas, such as health care and other sterile operating rooms or in food processing and storage facilities. Here, there is a zero tolerance for certain pests that can transmit disease or spoil food.

Monitoring

Monitoring is one of the cornerstones of integrated pest management (IPM), which seeks to reduce damage by using a combination of non-chemical tactics and targeted chemical treatments. Effective monitoring allows you to detect pest issues early, determine their severity, and choose the best control methods. It also helps you evaluate the effectiveness of your control efforts.

IPM monitoring is site-, crop- and pest-specific, requiring a variety of specialized tools and knowledge. Monitoring often involves inspecting a field or facility, examining traps, glue boards or sticky traps and evaluating pest logs. It also includes tracking weather and other environmental factors, recognizing the influence of natural enemies, and assessing whether pest populations are being kept in check by natural predators or increasing due to other reasons.

Food plant and warehouse quality control programs rely heavily on monitoring to detect problems, determine the severity of infestations, and evaluate the effectiveness of both non-chemical and chemical controls. Without proper monitoring, it can be difficult to manage pests and meet third party audit standards and regulatory compliance.

Insect light traps are one of the most common tools used for stored product pest monitoring in the food industry. These traps attract a wide range of flying insects, including cigarette beetles, Indian meal moths and warehouse beetles, which can be an indicator of a potential insect problem. By monitoring how many pests are captured, you can track the rate of infestation and identify the species that are present.

Regular inspections with a flashlight are another important tool for identifying pest issues, as these pests like to hide in dark places such as corners and crevices. Regular inspections can help to identify a pest issue before it becomes an infestation, which can save money on both costly pesticide treatment and unnecessary repairs.

Another way to assess the effectiveness of your pest control program is to look at how much bait is consumed in your rodent station or rat bait stations. This information can tell you how well your pest control program is working and whether you need to increase the frequency of inspections or change baits. Alternatively, it can also indicate that your traps may not be effective and you need to adjust their placement within your facility.
