Prevention is the best way to manage pests and reduce the need for control measures. It’s also the most environmentally conscious approach to pest control. This is because pest prevention focuses on practices that aren’t toxic to humans or pets and doesn’t involve using chemicals to kill bugs directly.
There are three types of prevention:
Sanitation – Cleaning practices that eliminate conditions that invite pests to invade. This includes regularly wiping down counters and floors, removing trash often and sealing entry points to homes and buildings. It also means sanitizing drains that can become breeding grounds for pests, such as small flies.
Climate – Weather conditions influence pests by killing or suppressing them and by affecting the growth of their host plants. This can be accomplished by varying temperatures, day lengths and humidity.
Natural enemies – Birds, reptiles, amphibians and fish prey on many pests and reduce their numbers. Likewise, some insects and pathogens attack and destroy pests. This type of natural control is free and usually more effective than synthetic methods.
Physical or mechanical controls – Devices, screens, traps, fences, radiation and electricity help control pests by physically altering their environment. These can include adjusting temperature, humidity and light levels.
Chemicals – Pesticides, herbicides, fungicides and other substances are used to kill pests directly or to prevent them from reproducing. They can be found in sprays, powders, liquids, baits and other forms.
Other substances – Bacteria, viruses, and nematodes can be used to kill or control certain pests. They are often more effective than insecticides and fungicides, which are often damaging to the environment.
Eradication – The goal of eradication is to remove an entire pest population. This is often difficult to achieve in outdoor settings, where the number of pests may build up over time. However, eradication programs do exist for some urban pests, such as Mediterranean fruit fly and gypsy moth.
Pests come in all shapes and sizes, from ants and roaches to rodents and bedbugs. But they all share some basic needs: food, water and shelter. That’s why it’s important to know the basics of pest management: what they are, how they reproduce, and the most effective ways to stop them from invading your space.
Suppression
Many natural forces affect pest populations, including weather, natural enemies, available shelter and food, and the ability to reproduce. These influences may help or hinder pest control efforts. Identifying and monitoring pest numbers through surveys or scouting (looking for and identifying pests) is a critical step. Identification helps to distinguish between continuous, or recurring, pests that require regular control, and sporadic, or migratory, pests that require only occasional control. It also can help determine whether a pest population is growing too rapidly and needs to be suppressed.
Suppression techniques include crop rotation, the use of disease-resistant crops, and the release of predators or parasitoids that attack the pests. Biological controls often involve mixing different natural enemy species to maximize their effects. For example, using parasitoids and ground-dwelling predators that target different stages of a pest’s life cycle enhances their combined impact in controlling pest populations, as illustrated in an experiment involving the oilseed rape plant.
In addition, pheromones that mimic the natural pheromone emitted by female insects can confuse males and interfere with mating. This can significantly reduce pest populations, as can the use of juvenile hormones to prevent pests from maturing and reproducing.
Chemical pesticides can be used to suppress pests that persist despite efforts at prevention and suppression. However, the use of chemicals can increase the risk of pest resistance to those pesticides, especially if the same chemicals are applied repeatedly over wide areas. Rotating pesticides and using those that are less toxic to the environment can help reduce the chance of developing resistance to a particular pesticide.
A deeper understanding of the relationship between landscape context and the flow and stability of natural pest control services can help develop methods that allow growers to decrease their dependence on pesticides while maintaining high crop yields. For instance, adding a temporal dimension to the effect of natural enemies on pest populations could help understand the synergistic and additive effects of different natural enemy guilds on pest control services and how these effects are affected by landscape context. For example, it is possible that a combination of parasitoids and ground-dwelling predators might have an additive effect when attacking different periods of the pollen beetle’s life cycle in the field, but that this interaction could be reduced by intraguild predation when the enemy predators consume parasitized prey within their body, as has been shown experimentally.
Eradication
Eradication is the process of removing a pest from a particular location. It can be achieved through a number of methods, including chemical, biological, and physical control. Eradication is typically only undertaken in cases where other methods have been unsuccessful. In order to be successful, an eradication program must be carefully planned and executed. To achieve this, it is important to consider all aspects of the pest control process – prevention, suppression and eradication – as well as environmental and economic factors.
2.4 Feasibility of undertaking an eradication programme
The feasibility of eradicating a pest depends on a range of factors, including the impact of the pest, the extent of the infested area, and the predicted rate of spread. This can be determined through a pest risk analysis (PRA) which provides a scientific basis for decision-making (see ISPM 2 and ISPM 11). In addition to the risk assessment, the feasibility of eradication should also be judged in terms of current technology and available resources. Possible eradication options should be described with their costs and benefits, recognizing that there is no guarantee that a specific option will be successful.
A classification tree can be used to identify the most important factors in determining success or failure of an eradication campaign. To this end, we collated data from eradication campaigns against invertebrate plant pests, plant pathogens (viruses/viroids, bacteria and fungi) and weeds from the world and analysed them using a standard model.
We found that the most important predictors of eradication success were reaction time and the probability that critical sanitary measures were implemented. These were significantly more important than the species or location of the invasive pest. The latter factors cannot be changed by the managing authorities and thus have been placed further down in the classification tree (Fig 1).
In addition to planning the eradication program, an NPPO should implement a communication strategy with stakeholders. This is essential to raise awareness of the eradication efforts and the importance of the work being carried out. It should also include public information programs and the possibility of involving local communities in the eradication process. Documentation of all stages of the eradication program is also necessary in case NPPOs of importing countries request proof that the pest has been eradicated.
Treatment
A pest infestation isn’t just a nuisance—it can be dangerous. Insects, rodents and even fleas can spread disease and contaminate food, and can make asthma and other respiratory conditions worse. For this reason, it’s important to get professional treatment as soon as you notice a problem.
You can handle some pest problems on your own with glue traps and sprays from the hardware store, but larger infestations require professional treatment to eradicate them completely. This may involve setting traps, spraying, fumigating and other methods that depend on the type of pest, the extent of the infestation and how it’s entering your home or commercial property.
Some of these treatments can be dangerous if not done correctly. Pest control professionals are trained to safely and effectively use chemicals, reducing the risk of exposure to family members and employees. They can also develop targeted treatment plans that address the specific pests, preventing their return and ensuring long-term pest control.
The first step in preventing pest infestations is to remove the attractants. Store foods in sealed containers, remove garbage regularly, and don’t leave out open food or drinks. Clutter is another common attractant, so be sure to clean often and close off places where pests breed or hide.
Many pests enter homes or commercial properties through gaps and crevices. For example, brownstones and other older buildings have tiny gaps where ants, mice and other small pests can crawl through to enter. These pests can ruin food, damage your building, and create a fire hazard. Likewise, rats can easily access electrical wiring through gaps the size of a dime.
If you do have a pest infestation, it’s important to contact a company that specializes in commercial and residential pest management. Ask for a quote and compare contracts so you understand how much you’ll be charged for the initial treatment and any follow-up visits. Make sure the company you hire is licensed and insured, and is willing to work with your budget to prevent pests from damaging your property and putting the health of family members or employees at risk.
