Pest Control Vancouver BC involves the destruction of organisms that damage or spoil crops, plants and livestock. Pests include rodents, birds, insects and plant diseases.
Pests are often controlled by removing food, water and shelter. Preventing infestations includes regular garbage removal, storing food in sealed containers and avoiding overwintering sites like hillsides and gulleys.
Infestations of pests can pose serious health risks to consumers and workers, as well as damage products and structures. Pests can carry disease-causing agents, such as cockroaches and rodent droppings; they can contaminate food products by consuming or chewing through packaging or foodstuffs; and they can cause direct damage by gnawing at wires or other structural elements.
While pest control treatments can be effective in eliminating infestations once they are present, it is more cost-effective and safer to prevent pest infestations in the first place. Preventive pest control focuses on the establishment of best practices for keeping pests out, such as sealing gaps and cracks in walls and other structures, making sure that trash bins are located away from entrances and are securely closed, storing food properly in airtight containers, cleaning regularly to eliminate sticky residues and making sure that doors sweeps and caulking are in good condition.
Structural prevention also involves locating and repairing leaking pipes to eliminate standing water, which is often a trigger for infestations, and using dehumidifiers in damp regions of the building, which can make them less hospitable to pests. In addition, it’s important to have a regular maintenance schedule for sweeping and vacuuming, sanitizing food storage areas and removing rotten produce from homes. It’s also essential to know your local waste collection day so that you don’t have trash sitting around for too long and can take it out before it attracts pests.
The most effective pest control methods are those that use natural enemies of a pest to suppress its population and limit the spread of its damaging actions, such as nematodes or fungus. These biological pesticides are applied to the soil, where they kill insects that ingest them by injecting them with a microbe. Because this type of pest control takes time to work, a monitoring program is usually required to determine the effectiveness of the treatment and its effects on the population.
The main problem with using pests to control pests is that they are easily disturbed by humans and can spread quickly if conditions for their survival are met. To prevent this, a regular scouting program should be in place to search for and identify pests, assess their numbers and damage, and then take appropriate action.
Suppression
The goal of pest control is to cause as little harm as possible to crops, the environment and humans. Prevention is the best strategy, and should be used before a pest problem develops. Pest management techniques range from physical modifications to the growing environment to chemicals that prevent pests or their damage. In a citrus grove, preventive measures include planting virus-free seeds and transplants, scheduling irrigation to avoid drought conditions that stress trees and encourage disease development, cleaning tillage and harvesting equipment between fields, and eliminating weeds that can provide food or shelter for damaging insects.
Biological control is another important part of IPM, and it relies on the use of natural enemies of crop pests to reduce their populations. This is a sustainable approach that reduces the use of toxic chemicals. However, it is important to understand how and when to apply these natural enemies. The first step is to accurately identify the pest; this will determine basic information about its life cycle and when it will be most susceptible to being controlled by a natural enemy.
Another way to reduce the need for chemical controls is by using pheromones to manipulate pest behavior. This is a relatively new practice, but it has proven very effective for some pests. For example, a synthetic copy of the pheromone that a female insect uses to attract males can be used to confuse the males and prevent mating. This can dramatically reduce pest numbers.
Most pest management programs use suppression as the primary method of reducing the population of a pest to an acceptable level. This is accomplished by monitoring pests and assessing their damage, or by observing environmental conditions that can predict when the pest population will reach an action threshold. The action threshold is the point at which control actions are required due to economic and ecological considerations.
The action threshold may be adjusted for a particular situation depending on the cost of pesticides, the value of the crop, and consumer standards. It is also important to know that not every action threshold will be reached; the number of pests that are present in a field depends on both the pests and the environmental and economic factors that govern their presence and damage.
Eradication
Pest control is the regulation or management of any animal, plant, or fungus that impacts negatively on human activities and environment. It can be achieved using a variety of methods, which range from tolerance, deterrence, and suppression to eradication. In general, eradication is a rare goal in outdoor pest situations where it is often more practical to focus on prevention and suppression. However, it is a common objective in enclosed environments such as homes, schools, office buildings, and health care, food preparation, and storage facilities.
When attempting to eradicate pests from an area, one of the main approaches is the use of natural enemies to decrease their numbers and/or eradicate them entirely. These natural enemies include predators, parasites, and pathogens. This method of pest control is also known as biological control. Often, this is accomplished by releasing predators or parasites into the area where the pests are present. However, this method can fail if the population of the pests increases faster than their natural enemies can manage.
Another approach to eradicating pests is the use of chemical controls. These are a broad category of pest control treatments that includes insecticides, herbicides, and fungicides. They are typically applied via sprays, granules, or dips and can be very effective in killing and repelling pests. However, these chemicals can be harmful to humans and the environment if not used correctly. Therefore, they must be carefully monitored and controlled.
One extreme of chemical pest control is fumigation, which involves sealing an entire building and pumping it full of chemicals to annihilate any pests inside. While this is a very effective method of eradicating pests, it can be extremely hazardous to the health and well being of those within the building. Therefore, it is only used as a last resort or in very severe pest infestation situations.
Pest control is a complicated process that requires many different techniques and strategies to be successful. It is generally best left to professionals who are well versed in a variety of methods and know how to properly implement them for the most comprehensive results.
Natural Forces
Pests interfere with our quality of life in many ways. Some damage crops and property, while others transmit disease to humans, livestock and other organisms. Still others are simply objectionable, as in the case of flies, mosquitoes, rodents and other insects. In some instances, such as in a home or business, their presence can be so irritating that they must be exterminated.
Natural forces – such as weather and topography – limit the spread of some pests. The availability of shelter, food and water can also affect their numbers. Threshold-based decisions are a good practice when determining pest control strategies. For example, observing a few flea beetles in the garden probably does not warrant action; however, seeing them in increasing numbers may indicate that it is time to spray.
Biological controls make use of predators, parasites and diseases to reduce the numbers of target pests. These are called natural enemies and they can be introduced intentionally or fortuitously. For example, nematodes can be introduced to the soil to attack grubs that harm vegetables. Biological control methods are generally less damaging to the environment than chemical control, although the timing and intensity of their application must be carefully considered.
Other forms of cultural and mechanical controls can help to manage pests. These include rotating and cultivating the soil, changing the timing of planting or harvesting, varying row width, thinning, pruning and placing trap crops. All of these can alter the conditions that support pest populations and limit their ability to thrive, so they are a valuable part of any pest management program.
Eradication is rarely the goal in outdoor pest situations, but it can be attempted when a foreign species has been accidentally introduced to a new area and must be eradicated to prevent its spread. For example, eradication efforts are underway for the Mediterranean fruit fly, gypsy moth and fire ant. Eradication is more common in enclosed areas such as homes and businesses, where it can be more easily achieved. Regular inspections of such areas can allow pests to be detected early and prevented from entering or spreading.
