Natural Pest Repellents: Plants That Keep Bugs Away
Pest Control Bridgewater NJ involves identifying and controlling organisms that damage plants, animals or property. It can be done with natural, biological, chemical, cultural, mechanical or regulatory controls.
Natural forces like climate, natural enemies and availability of food and shelter limit pest populations. Continuous pests require regular control; sporadic and potential pests need only control when conditions favor them.
Typically, pests are animals, but they may also include microorganisms such as bacteria and fungi. In addition, some plants are pests; they damage their host or degrade the surrounding environment and produce toxic by-products. Most organisms that become pests do so because of environmental modification, often from human activities. Pests are not inherently destructive; they are usually only damaging when their numbers exceed acceptable levels. Some pests carry pathogens that cause disease in humans and other organisms. These diseases are sometimes life-threatening, as in the case of West Nile virus spread by mosquitoes or Lyme disease spread by ticks. Some pests are irritants, making people uncomfortable or causing damage to their property.
Pests can be controlled by preventing them from entering the collection and by removing items infested by them. Traps, screens, barriers, and fences can all help prevent the movement of pests into a collection area. In addition, physical controls such as refrigeration and radiation can control some pests, particularly insects.
Some pests are easier to control than others. Insects, mites, and nematodes can be monitored by trapping or scouting, and the damage they cause can be assessed visually. The monitoring of vertebrate pests such as rats and mice can be accomplished by observing their activity or tracking the signs they leave behind.
Natural enemies of pests can limit their densities, and some species can be bred for this purpose. In the classic biological control method, these predators and parasitoids are bred in the laboratory and then released into the field, paying attention to the timing of both the natural enemy and pest life cycles. Alternatively, the natural enemies can be obtained in the wild and then introduced to an area where they are not well established, in order to augment their population and provide long-term control.
The decision to control a particular pest depends on its effect on the collection, its impact on people, and its ability to be controlled without using toxic chemicals. The ultimate goal is to restore collections to their pre-infestation condition and to minimize losses to future generations by reducing pest populations to an acceptable level. This is often accomplished through prevention, but it can also be accomplished through suppression and eradication of the pest.
Pathogens
There are five main types of pathogens: viruses, bacteria, fungi, protozoa and worms. Every living thing carries one or more of these microorganisms and they can cause disease in humans, plants and animals in a number of ways. They can damage tissue directly, or they may interfere with reproduction or movement through the environment by producing toxins. Bacterial toxins, for example, are among the deadliest poisons known and include such notorious examples as tetanus or anthrax.
Viruses, bacteria and fungi infect cells in order to replicate. They can then use these cell walls to gain entry into other tissues or cells. Once inside a host cell, they can spread their genetic material and produce the proteins that affect their host. They can also release toxins that directly harm their hosts, such as the lethal ones that caused the bubonic plague epidemic of the 18th century.
Pathogens can spread from person to person through common activities such as coughing or sneezing, eating food that has touched the ground, changing a diaper or petting an animal. They can also be transferred through the air by breathing or by touching surfaces in a contaminated environment.
Once a pathogen gains access to a new host, it can usually multiply within the body, but it must also avoid damaging the host’s cells in order to remain virulent. This process can be interrupted by the host’s immune system, and a reduction in virulence often results. For example, Yersinia pestis, the bacterium that causes plague, is normally a harmless intracellular obligate parasite in rodents and fleas, but when it leaps to infect humans, it becomes deadly pneumonic plague.
Some pathogens pass the winter as dormant spores in the soil or on other vegetation. For example, the fungus Entomophaga maimaiga that controls gypsy moths in forest ecosystems of eastern North America overwinters as resting spores on the leaves and branches of trees. It germinates and kills gypsy moth caterpillars when they come into contact with the spores in spring.
The success of biological control approaches to weeds, fungi and arthropod pests depends on an understanding of the physiology and behavior of the organisms involved. This requires the collaboration of soil physicists, meteorologists and computer modeling experts as well as plant breeders and geneticists.
Pesticides
Pesticides are substances used to prevent, destroy or control unwanted organisms (plants, insects, weeds, pathogens) that damage crops, livestock and property. They can be in the form of liquids, solids or gases. Pesticides are a valuable tool in agriculture, but their adverse effects on ecosystems and human health can have far-reaching consequences.
The majority of pesticides reach destinations other than their intended targets, and they often accumulate in soils and waterways. This can lead to the contamination of food and drinking water. They can also harm humans, causing short-term impacts like headaches and nausea or long-term impacts like cancer and reproductive harm.
Many insecticides (including pyrethroids, organophosphates and carbamates) attack an organism’s brain and nervous system to kill it. These chemicals are usually the most acutely toxic to humans and animals, but can also have a long-term detrimental impact. For example, repeated exposure to pyrethroids can result in nerve disorders such as Parkinson’s Disease. Herbicides are generally less acutely toxic, but their chronic effects can increase the risk of a number of diseases and conditions, including heart disease, infertility and cancer.
Most commercially available pesticides are mixtures of two or more active ingredients. The identity of these ‘inert’ ingredients is confidential business information and therefore not listed on the product label. However, they typically make up more than 95% of the total product.
Pesticides may be formulated as a liquid, solid or gas and are applied to the ground or to plant surfaces. The different forms they come in influence how they enter the environment and are absorbed by plants and humans.
For instance, sprays and powders are usually a lot more dangerous to people than liquids and granules, as they can be inhaled into the lungs. The way they are stored and used also influences their impact on the environment.
In order to reduce the amount of pesticides entering the environment, always follow the manufacturer’s instructions carefully and use the least amount possible. Remove or cover personal items, like utensils and trays, before spraying and make sure you leave the room while the surface is wet.
Safety
Pests are organisms that cause or threaten to cause damage. Damage can be economic, environmental or health-related. Control is a means to reduce their numbers or their damage to an acceptable level. There are four types of control: prevention, suppression, elimination and eradication. Prevention is the most cost effective as it avoids the need to control pests. This can be achieved through physical methods such as exclusion, quarantine, trapping and sonication or chemical methods such as herbicides, insecticides and biopesticides.
It is important to remember that even organic pesticides are toxic to a certain degree. Therefore, it is recommended that all employees and customers of food companies undergoing pest control treatments, wear rubber gloves, wash their hands and remove any personal items that might come into contact with them after the treatment. It is also important that all products used for pest control are applied in a way that prevents any exposure to anyone outside the company. Proper ventilation is key in ensuring this as it allows dangerous concentrations of chemicals to dissipate quickly, protecting those applying and receiving the application from any health risks.
In addition, the company undergoing pest control should be sure to take steps to keep their facility in good condition and identify any factors that might increase their pest activity such as holes in the walls or floor, leaky machinery or a source of food like old garbage. These measures might include removing potential nesting spots or perch areas such as light fixtures and ensuring that there is no access points for pests such as rodents which can fit through openings a fraction of their size and cockroaches which can crawl through half an inch cracks.
The company should also be sure to follow the recommendations made by the pest control professional or the product label as they may include specific cleaning and post-treatment procedures that must be followed. These might be things such as a waiting period or specific cleaning and washing procedures that must be completed before the next treatment is applied. These measures can be a vital part of reducing the amount of pesticides that need to be used in a facility.
