Pest Control 101: Fundamentals and Strategies

Pest control is a complex field. There are many chemicals and methods to choose from, each with advantages and disadvantages.

Preventive steps include removing sources of food, water and shelter, fixing leaks, storing and disposing of garbage properly, cleaning up debris, and closing off places pests can hide or breed. Contact Pest Control Ballwin MO for professional help.

The best way to control pests is through preventive methods, such as regularly cleaning facilities and storing food in sealed containers. This helps to eliminate potential attracting elements, such as crumbs and garbage, that can encourage pests, and reduces the chance of infestation. It is also important to keep spaces clean and organized, as rodents, insects and other pests thrive in cluttered areas. This includes regularly removing garbage, cleaning up spills, and fixing leaky pipes.

Physical barriers such as screens, netting and mesh are often used to block or restrict pests from entering buildings, gardens or crops. They can be very effective against some pests, especially for preventing rodents from gaining access to a building. They are often combined with other types of controls, such as traps, poison baits or electric light traps, to provide an integrated approach to pest control.

Chemical pesticides are a very common method of controlling pests. These chemicals are designed to disrupt the nervous system or metabolism of targeted pests, killing or repelling them. However, they can also harm non-target organisms and the environment. Therefore, their use is usually a last resort, after other controls have been used and they are still needed to protect the environment or human health.

Biological controls are often used in combination with other control methods to help reduce the need for chemical treatment. Biological controls utilize bacteria or viruses that target and destroy specific pest species, without harming other organisms. This method can be very successful, and is particularly useful for reducing the use of more toxic pesticides. For example, the natural bacterium Bacillus thuringiensis (Bt) is often used to control caterpillar populations by producing toxins that kill them when ingested.

Habitat modification is another preventive control technique. This involves changing the habitat of pests by removing or altering their food, water, shelter or other requirements. This can be done by removing their breeding sites, destroying their nests or introducing plants or other organisms that are natural predators of the pests. For example, planting marigolds in a garden can help to control nematodes by emitting chemicals that repel them.

Suppression

Pest control is the attempt to keep a pest population below a level where the harm it causes is unacceptable. This usually involves a combination of methods and is a continuous effort. It often requires a change in the environment to make it less attractive or acceptable to the pest in question. It may also include a use of natural enemies or the augmentation of those natural enemies by artificial means.

Preventing pests is generally less expensive and more effective than attempting to eradicate an established pest problem. It is important to identify and remove the things that attract pests, such as food or water. Store garbage in tightly sealed containers, don’t leave pet food or water out overnight, fix leaky pipes, and keep lawns and gardens properly maintained.

In some cases, a particular species of plant or animal has genetic characteristics that resist the effects of a given pest. Using this resistant variety when possible can help reduce the amount of pesticide needed to maintain good health and yields.

Biological control involves the use of natural enemies such as predators, parasites and pathogens to manage pest populations. These organisms injure or kill the pest, limit its spread and/or cause it to reproduce more slowly. This is a common and environmentally friendly approach to managing pests.

Cultural controls, such as changing cultivation practices, can greatly reduce pest problems. Mulching soil to discourage weeds, for example, can be a very successful control method. Changing irrigation systems to minimize excessive watering, which can promote root disease or fungus, is another control method.

Chemical controls, including a wide range of pesticides, are sometimes necessary in achieving satisfactory pest control. However, this should be a last resort and only the product that is least likely to affect humans or the environment should be used. It is essential to accurately evaluate the pest infestation, the environmental conditions that made it possible and to determine how serious or damaging the pest is.

Integrated Pest Management (IPM) is an environmentally responsible and economically sound approach to pest control that emphasizes prevention, monitoring, suppression and when necessary, eradication. It encourages the use of natural, biological and physical controls rather than pesticides whenever feasible.

Eradication

Pests such as rodents, cockroaches, bed bugs and other unwanted creatures can pose health issues and property damage. While it is tempting to grab the insect spray and squirt away, it’s always best to get professional help. This is because these experts are well-versed with different methods and possess the right knowledge to completely eradicate them. There are many ways they can do this, depending on the type of pests and the environment where they’re found.

A common chemical pest control method is ultra-low volume fogging, which pumps tiny drops of pesticide into the air to kill them. Another option is fumigation, which involves sealing a building in a bag full of gas to annihilate pests inside. These methods are usually used in agriculture to protect crops from pests, but they can also be used indoors to rid an office or commercial facility of insects and other pests.

Another way to eradicate pests is to introduce their natural predators to the area. This is one of the oldest forms of pest control and it involves placing the predators in the same habitat as the pests to manage their population. It’s also important to remove the pests’ food sources and water sources. For example, fixing a leaky faucet will eliminate an easily accessible food source for pests and will make your workplace less welcoming.

Biological pest control is an eco-friendly alternative to traditional chemical solutions. This includes using organisms that naturally occur in the environment to control pest populations, such as bacteria or viruses. Bacillus thuringiensis, better known as Bt, is a common example of this kind of biological pesticide. It is a naturally occurring soil bacteria that has been developed into strains that target specific pest species. When ingested by caterpillars, Bt releases toxins that kill them.

Other types of biological pest control include the use of nematodes and parasitic wasps to control pests. Nematodes are microscopic worms that live in the soil and feed on insects. They’re a great alternative to chemical pesticides, but they may not be effective against all types of pests. Wasps, on the other hand, can be trained to attack specific kinds of pests.

IPM

IPM is an environmentally sound method of managing pests in homes, schools and gardens without using harmful chemical products. Developed as an alternative to steadily increasing pesticide use that resulted in pest control crises (outbreaks of secondary pests, pesticide resistance) and awareness of the full costs of pesticides to human health and the environment, IPM combines biological, physical, cultural, crop specific and environmental methods to manage pests in a sustainable way.

IPM starts with proper identification of the pest. This allows the grower to determine if there are preventive nonchemical methods available to reduce pest populations. IPM also includes monitoring and record keeping to ensure that pest populations do not reach damaging levels. When a pest problem does occur, IPM includes action threshholds so that controls are used only when necessary.

Preventive nonchemical methods can include removing the pest’s food, water or shelter, blocking their entry into a home or garden and altering planting or cultivation practices to make the plants less attractive to the pests. Chemical preventive controls can include insecticides, fungicides or herbicides. These materials must be selected carefully to limit their impact on beneficial insects and other organisms.

Integrated pest management involves combining biological, organic, cultural, physical and mechanical, and educational strategies to reduce the risk of damage to crops, gardens and landscapes. Although IPM was originally focused on insect pests, it has been expanded to include diseases, nematodes, weeds and even wildlife. IPM also relies on the advice of specialists, such as entomologists, plant pathologists and weed scientists.

If nonchemical prevention and suppression options fail, IPM includes a range of more aggressive treatment options. These can include spraying or baiting, and may require more than one treatment. IPM also encourages the use of fewer pesticides, and ensures that any pesticides applied are used in a responsible manner.

An IPM plan is a valuable tool for homeowners and gardeners, as well as commercial growers. While an IPM program will take longer to show results than simply spraying a chemical, the long-term benefits of a low use of pesticides, along with a reduced impact on beneficial insects and other organisms, make it a sound choice.
