Protecting Your Home from Pests

Pests cause damage to plants, crops, buildings and structures. They also affect our health by spreading disease like hantavirus pulmonary syndrome, leptospirosis, plague and salmonella.

Pest Control

Taking steps to prevent pest infestations can help control them. Physical methods include traps, screens, fences, radiation and modifying the environment. Chemical methods include pesticides. Contact the professionals at Pest Control Braintree.

Pest identification is the first step in any pest control program. Accurate pest identification allows the use of appropriate control tactics, including cultural practices, biological controls, or chemical treatments. Incorrect identification can lead to the use of ineffective treatment methods or unnecessary pesticide application.

Proper pest identification requires familiarity with a specific pest’s biology, life cycle, and behavior, as well as its environmental requirements. This information is crucial in the development of integrated pest management strategies, reducing the need for harmful chemicals and improving the safety of both people and wildlife.

Often, pests can be difficult to identify because they may look similar as they mature or develop through different stages of their life cycles. This can be especially true for caterpillars, grubs, and worms, as they undergo their metamorphoses. However, a careful examination of the damage caused to a plant may reveal clues about the identity of the pest, such as the presence of feeding indicators or symptoms of disease.

It is also important to remember that poor plant growth and damage are not necessarily caused by a pest, and that sometimes the problem can be remedied through other means, such as soil fertility or cultural practices. The use of inappropriate pesticides could also be wasteful, and excessively burden the environment.

Once a pest has been identified, it is important to note the characteristics of its host plants and environmental conditions that favor its development and spread. This knowledge will allow a grower to recognize and anticipate the arrival of a pest, and take steps to prevent its entry into the crop.

Some pests can be identified by using a hand lens, while others require a microscope or other specialized equipment. When a particular pest is not readily identifiable, it can be helpful to consult a variety of resources, including printed and online guides, or to ask an expert at a local University Extension office for assistance. If necessary, a sample can be sent to a specialized laboratory for identification. The National Identification Services (NIS) at APHIS Plant Protection and Quarantine provides the final taxonomic authority for plant pest identifications, and works closely with experts in botany, entomology, and malacology stationed at Federal research laboratories, State departments of agriculture, land-grant universities, and natural history museums.

Prevention

Prevention is about taking action to prevent pests from invading your property or damaging your crops before they can do any damage. This is done by changing the conditions on your land that make it more or less attractive to pests. The idea is to eliminate the pests’ reason to come to your site, so that they will choose to go somewhere else. Prevention is a large part of what is known as integrated pest management, which is a combination of control methods that reduce the need for and risk associated with chemical treatments.

Prevention may include changing cultivation or gardening practices to make them less hospitable to pests. For example, rotating crops or choosing varieties that are less prone to disease can prevent the build-up of pest populations. It can also involve removing things that attract pests, such as trash cans without lids or leaking water sources. It can be as simple as sealing the smallest cracks and crevices, ensuring that garbage cans are tightly sealed, and making sure there are no puddles or standing water where pests might seek shelter. It can be as complex as restoring native habitats around fields or homes to provide food and shelter for natural predators and parasites that will take care of some pests.

In residential pest control, prevention can mean removing the places where pests can find food, water and shelter. It can include keeping garbage receptacles closed and regularly removed, fixing leaky plumbing, removing standing water, and not leaving pet food or water out overnight. It can also include regular inspections and cleaning to detect pests before they have a chance to cause harm, and installing screens on doors and windows to keep them out.

Prevention can also involve education and awareness, such as learning about the lifespan and life cycle of common pests. This can help you understand how long it will take for pests to reach the point where they need to be controlled, so you will know when to expect them. It can also be helpful to know which stages of the pest’s life cycle are most vulnerable to controls, so that you can target those phases with your controls.

Suppression

Keeping pests below damaging levels requires prevention and suppression tactics. Preventive measures include regularly cleaning sites where pests may live, as well as identifying and eliminating conditions that encourage pest development. Suppression includes quickly taking action to limit pest population growth once an infestation occurs. Eradication, which destroys the entire pest population, is seldom a goal in outdoor situations but can be used in indoor areas such as operating rooms in health care facilities where zero tolerance for pests exists.

Many natural forces affect the numbers of pests, including climate, the availability of food and water, predators, natural barriers and overwintering sites. These factors often interact and can help or hinder efforts to control pests.

Plants, animals and wood products have natural resistances that can keep pest populations below damaging levels. Incorporating resistant varieties into a landscape can help control pests and maintain plant health.

Some plants and trees provide shelter to animals and birds that can kill or disturb other pests. Including these types of plants and structures in a landscape can make an area more attractive to wildlife, which can then suppress pest populations.

Chemicals in the environment — including soil, air and water — can also affect pests. This category of controls includes herbicides, insecticides and fungicides. Federal, state and local laws govern the use of these chemicals and are designed to protect human health, the environment and other organisms.

Another form of chemical control involves the addition of certain microorganisms to the soil to reduce pests. This is known as augmentation or biological control. Commercial products available for this purpose include microbial insecticides, which contain bacteria and fungi such as Bacillus thuringiensis. These are most effective when applied at low levels to reduce their impact on other microorganisms in the environment.

Releasing natural enemies to reduce pests can be cost-effective when the release level and timing are carefully selected. This requires a thorough understanding of the pest(s), natural enemies, habitat and economic goals. This is a relatively new technology and research continues to be needed to optimize releases.

Control

A pest control company uses a variety of methods to eliminate and prevent a problem with unwanted organisms. These organisms can spread disease, contaminate food and damage property. Pests infest homes, restaurants, hospitals, and other commercial establishments. Keeping pests under control can ensure the health and safety of people working in these buildings.

Most commonly, pests are controlled using pesticides. Pesticides are chemical substances that kill or control organisms that are considered a threat to human, animal or plant health. They include herbicides, insecticides, and fungicides. Pesticides are used in agriculture to protect crops from weeds, insects, and fungi, and in households to kill household pests such as ants and cockroaches.

Another common method of pest control is to use heat or cold to kill the pests. Hot water sprays or freezing temperatures can be used to kill bedbugs, fleas, flies, mosquitoes, and spiders. Several companies produce products that can be used in this manner. In addition, some foods are preserved with heat or ice to keep pests from eating them.

One of the oldest forms of pest control is to introduce the organisms that naturally compete with a species of pest. This type of pest control is also called biological control. This process requires extensive research into the biology of the pest, and potential natural enemies. It requires the proper collection of these organisms, and careful quarantine to remove any pathogens or parasites that could affect the natural enemy population. It is necessary to release them at the correct time in the pest and predator life cycles, and in a habitat suitable for the natural enemy.

Other chemical pest control methods include ultra-low volume (ULV) fogging, which sprays small amounts of pesticide, and fumigation, a process that involves sealing a building and filling it with pesticide gas to annihilate the pests. However, these are usually only used in extreme situations.

Integrated Pest Management (IPM) is a process that includes all of these types of treatments in a plan to reduce pests to an acceptable level. It is the best way to minimize disruption to living and nonliving environments, and to reduce risks of harming people or property.

The Impact Of Climate Change On Pest Populations

Agricultural production depends heavily on climate variables, like temperature and water availability. Because insect pests are closely linked to these factors, short-term climatic extremes can have significant impacts on crop productivity.

Global warming is expected to increase pest populations, which could result in substantial economic losses for agriculture. Temperature changes influence phenology, particularly in univoltine species and those with shorter life cycles. Click Here to learn more about how to deal with pests.

Temperature

Depending on the species, temperature changes can dramatically affect the growth rate of pests. This is due to the metabolic and reproductive processes of insects being influenced by their thermal optimum. For instance, high temperatures accelerate insect metabolism and fecundity while low temperatures slow down these processes. Therefore, warmer climates can increase the number of generations per year, resulting in a rapid build-up of pest populations that threaten crops.

Temperatures also impact insect behavior and movement, causing them to move to new areas. For example, increased summer heat can cause a tree-feeding pest to move into a cropping region. Similarly, drought conditions can allow invasive plant pests to advance from incipient populations to epidemic status. These factors can be amplified through feedback mechanisms within the insect-host species complex, resulting in highly variable within-species responses to climate change.

Precipitation changes can also impact pests by influencing their habitats and water sources. In general, precipitation can lead to an expansion of the pest overwintering range or an increase in the breadth of their breeding and feeding habitats.

However, the impact of changing temperatures on pests is likely to be more dramatic because it can also affect the predatory capacity of a species. As temperature increases, the metabolic rate of predators decreases and their ability to kill pests deteriorates. This can reduce the impact of predators on pest populations and facilitate their spread and growth.

Scientists agree that climate change is causing shifts in the distribution of many pest species. However, it is still difficult to predict how and when these shifts will happen. To make these predictions, scientists need to understand how climate change impacts the geographic range of a pest species and identify the specific aspect of climate change that is altering its distribution. This involves developing mechanistic models that take into account factors like climatic variables, population dynamics, host plant traits, and anthropogenic disturbances. It also requires incorporating data at finer geographical scales. For example, incorporating the behavioral thermal regulation of microhabitats could help improve predictions by buffering temperatures from extremes, but this requires reliable daily data at the habitat scale.

Precipitation

In addition to temperature change, precipitation can also have a significant impact on pest populations. Precipitation can influence a pest species’ ability to persist in a region, or it may impact the duration and magnitude of an insect-borne disease outbreak.

Many major crop pests, such as aphids and whiteflies, are disease vectors that transfer viruses to crops that cause serious plant diseases. Climate change can affect the virulence of a virus, which can increase its transmission to new host plants or spread from an existing host population.

A change in the amount of available moisture can also affect pests, influencing their growth rate, fecundity, and mortality. If the available water supply decreases or becomes less uniform, pests can become more abundant in a given area, or they may be forced to move elsewhere to find sufficient water.

The recent desert locust outbreak in the Horn of Africa is an example of how a shift in weather patterns can lead to the rapid development of new and devastating pests that threaten global food security. Skyrocketing global trade and climate change will likely amplify native and invasive pest frequency, necessitating the need for adaptive measures to mitigate their adverse effects.

Climate change can also disrupt natural enemy dynamics, which can further exacerbate pest populations and reduce the effectiveness of control strategies. For example, a rise in temperatures can accelerate the phenological cycle of multivoltine insects, such as aphids and cabbage white butterflies, allowing them to have more yearly generations.

This phenological mismatch between pests and their natural enemies can debilitate biocontrol efforts and further enlarge pest populations, which in turn will lead to higher crop damage. The same effect can occur in the case of climate-mediated changes in resistance to insecticides. If pests can persist in new regions because of weather changes, they will also be able to build up resistance to the most common insecticides. As a result, the use of more effective and expensive resistance management tools will be necessary. This will inevitably increase the cost of food production.

Water Supply

Many crop pest species require a steady supply of water to grow and reproduce. Changes in temperature and precipitation can affect their ability to access this water, impacting the growth rates and emergence of populations. The frequency of extreme weather events, such as heat waves and heavy rains, is also changing globally and increasing in intensity.

Climate change alters the geographic distribution of insect pest species, moving them into regions they would not have occupied otherwise. This expansion of their habitats can cause problems in agricultural production by increasing the number of pests that threaten crops, as well as by allowing them to develop resistance to common pest control measures.

The increase in atmospheric carbon dioxide concentrations produced by human activity impacts the metabolism of insects, altering their growth rate and development. In addition, a rise in carbon dioxide levels affects the absorption of nutrients by plants, and this can influence the growth rate of crop pests as well.

Warming temperatures have an impact on the biological limits of insects, which are determined by the optimal temperature for their life cycle and behavior. Deutsch and colleagues studied these effects in models of insect population dynamics, factoring in metabolic and reproductive responses to temperature changes for aphids and corn borers. The results showed that the optimum temperatures for these species are being moved northward so that these pests will be able to thrive in regions that were previously unsuitable for them.

As the climate continues to warm, populations of crop pests will be expected to expand their ranges to more northern and higher altitude areas, increasing the risk of damage to global crops. Moreover, the occurrence of hotter and drier climates will make it more difficult to manage insect pests by using conventional methods of pest control such as spraying and crop destruction.

In addition to influencing the overwintering range of pests, the effects of climate change on their resistance to common pesticides will also be significant. Because most resistant phenotypes are transient, they usually die off in cold winter temperatures or emigrate at the end of the growing season. As the climate changes, this effect is expected to increase in size and intensity.

Habitat

Since insects are ectotherms, they cannot regulate their internal body temperature and are therefore extremely sensitive to weather changes. Consequently, pest populations can be greatly increased by climate change, especially in the form of temperature rise.

Temperature affects several key insect characteristics, including growth rate and phenology. Increasing temperatures create conditions that make it easier for the insects to breed and grow. Moreover, warm temperatures help multivoltine pest species develop at a faster rate compared to univoltine ones. This can lead to a larger population size of pests and increase their damage potential.

Additionally, pests’ thermal development tolerance, which is measured by growing degree days (GDD), will also be affected by climate change. This parameter can be used to predict the number of generations that a particular insect species will be able to complete in a year. The higher the GDD, the more rapidly the insect will be able to mature.

A large part of the food we eat is grown by plants, which need pollination from insects to thrive. Hence, it is important to protect these insects from being overpopulated by pests. Unfortunately, climate change is disrupting this delicate balance and is jeopardizing the ecosystem services that these insects provide.

Changing habitat is also expected to have a significant impact on the distribution and population dynamics of pests and their natural enemies, which are important for crop protection. The interactions between these organisms play a critical role in the ecological system, and any disturbance can be catastrophic for biodiversity.

As climate change continues, it is expected to exacerbate the geographic ranges of both pests and their natural enemies, which will affect agricultural production. It is important to monitor the expansion of these geographic ranges to identify new areas where they can pose a threat.

Even though global warming makes it harder for crop parasites to survive in their natural environment, they will continue expanding their ranges as long as there are suitable host plants available. Recent outbreaks of crop diseases such as the fall armyworm and the desert locust in Africa have been caused by heavy rains that created the perfect conditions for these pests to thrive.
