Pests are organisms that harm plants and animals. They also can damage buildings and structures. Pests cause millions of dollars worth of damages annually to homes and businesses.
Pest Control Keller TX includes preventive methods, inspections, and treatments. Pest control methods are chosen based on the type and severity of the infestation.
Integrated pest management, or IPM, is a decision-making process that uses observations (inspections and monitoring) to make pest control decisions based on pre-determined objectives. It incorporates a variety of chemical and nonchemical tactics in an ecologically sound manner to minimize risks to people and the environment. IPM includes regular inspections, scouting, record keeping, and evaluation. The UC IPM website offers specific information and tools for pest identification, monitoring, assessment, and treatment options. IPM also promotes preventive strategies to reduce the occurrence of pest problems before they occur.
When a problem arises, IPM practices encourage using natural enemies to limit pest populations without resorting to toxic chemicals. Preventive nonchemical methods include:
- The removal of host plants.
- Changing cropping patterns.
- Adjusting cultural practices to alter soil conditions.
These techniques can effectively reduce pest numbers and prevent the need to apply pesticides.
IPM strategies deny pests food, water, and shelter to reduce their growth or reproduction. For example, by mulching around sun-loving plants to deprive them of their needed sunlight, IPM can reduce weeds that compete with crops for the sun. In addition, locating plants to get the best sun exposure helps to reduce fungal diseases that can infect leaves.
Incorporating IPM into a farm or garden can be time-consuming, but it’s an excellent way to reduce the use of pesticides and still achieve desirable plant growth. Farmers can implement IPM independently or in partnership with entomologists, plant pathologists, and nematologists. IPM also supports beneficial insects that prey on harmful pests, pollinate flowers, decompose organic material, and are a crucial part of healthy ecosystems. IPM is a smart, sustainable way to manage pests and their damage in school gardens and daycare facilities. It also creates a healthier learning environment by minimizing children’s exposure to pesticides and other chemicals.
Pesticides are chemicals used to kill or control pests. Pests include insects, mice or other animals, unwanted plants (weeds), fungi, or viruses. Pesticides can also be substances that prevent or reduce the damage a pest causes, such as fertilizers and soil conditioners.
The word pesticide describes a large and diverse group of substances and products, and it is important to get specific information about the product before use. Pesticides are manufactured from natural materials and may be derived from animals, plants, bacteria, or minerals. They can be biodegradable, meaning they break down rapidly in the environment into harmless compounds, or persistent, which means they take months or even years to break down.
Most people are familiar with insecticides, but many other types of pesticides exist. For example, algaecides kill algae in lakes, canals, swimming pools, and water tanks. Fungicides kill fungi. Rodenticides kill rodents, including rats and mice. Plant Growth Regulators alter the growth of crops; they may inhibit or promote flowering, induce fruiting, or stop seed production. Repellents repel unwanted pests, often by a combination of taste and smell. Molluscicides control slugs and snails. Wood Preservatives protect wood from fungus and insects.
Pesticides can be sprayed directly onto plants from sprayers or crop dusters or dissolved in water and applied with a hose. Some are systemic, meaning they move inside the plant through the xylem or phloem, while others remain on the surface and act by contact with the pest.
It is important to understand that pesticides are poisonous, and they can cause harm to humans and other living things. Many human health problems, from short-term impacts like headaches and nausea to chronic effects such as cancer and reproductive harm, are linked with exposure to pesticide residue in food, drinking water, and air.
Governments and agencies regulate agricultural pesticides to ensure they do not risk human life or the environment. Regulatory agencies set tolerance levels, which are the amount of a chemical that can be legally used in an area or a particular crop. A pesticide can be declared unsafe and banned when tolerance levels are exceeded. The Environmental Protection Agency’s (EPA) Pesticide Data Sheets give detailed information about each pesticide, including its toxic properties and how it works.
Biological control uses living organisms, natural enemies, to suppress pest populations and make them less damaging. These organisms include predators, parasitoids, and pathogens. Unlike chemical pesticides, which kill many organisms that may benefit crops and the environment, biological agents target specific pest species. Biological controls can be used against vertebrate and non-vertebrate pests, weeds, plant pathogens, and nematodes.
Compared to traditional chemical pesticides, the advantage of using biological controls is that they do not persist in the environment and do not damage soil or water quality. Biological agents can also be more selective than chemical pesticides and manage a wider range of plant species. However, using biological control requires patience because it can take up to ten generations to see significant results.
In addition to reducing environmental impacts, biological controls can be more cost-effective than chemical pesticides. In addition, they do not have the potential for developing resistance, as do many chemical pesticides.
The goal of biological control is not pest eradication; rather, it is to reduce pest numbers below an economic threshold. This threshold varies across plants and among growers, depending on how much crop yield or aesthetic appearance is important to them.
There are three main approaches to biological control: conservation, augmentation, and classical or importation. The first, conservation, involves utilizing the natural enemies in the field. The activity of these natural enemies can be enhanced through changes in field management practices or habitat to increase their effectiveness.
Another way to utilize natural enemies is to release them in large numbers to overwhelm a pest population (inundative release). This technique can be successful but requires careful insect identification to select an appropriate biological control agent. Knowing how a particular biological control agent feeds, reproduces, and overwinters is important to properly use it against the pest of interest.
The final way to utilize natural enemies is through “augmentation.” This means introducing new biological control agents through mass releases or individual placements. Examples of augmentation include the introduction of lacewings or lady beetles to the crop and planting entomopathogenic nematodes in the field to control soil-dwelling insects.
There are several ways to physically control pests, including removing them from their environment and blocking their access to food. Some physical methods kill the pests, while others simply deter them. Physical controls are often used in conjunction with biological and chemical control strategies.
Physical and cultural practices were utilized long before the advent of chemicals and played a role in all pest management programs. These techniques reduce pest attacks by making the crop environment less suitable for them or spatially manipulating their population through repelling or trapping. These methods do not use harsh chemicals, which makes them ideal for organic gardening and fit well with IPM programs.
Some natural forces affect pest populations, but you can often enhance their effects by using the right combination of control measures. Accurate identification of the pest is key to this process, as is understanding their life cycle and what conditions make them most vulnerable to attack.
Natural barriers, such as mountains and large bodies of water, restrict the movement of some pests. Food, shelter, and water supply availability also limit their growth. Changing their habitats by planting different crops or introducing new plants, animals, or soil types can also help.
Most pest control programs aim not to eradicate the pests but to keep their numbers below an acceptable threshold. This is especially important for crops not grown in greenhouses, such as field and vegetable gardens. Pests in these areas can hurt the health and productivity of crops nearby, as is often the case with vegetables planted next to a field of cabbage that attracts slugs.
In many cases, combining several different control tactics is the best approach to managing pests. The combination will usually result in lower-than-average levels of pest damage. Using the right combination will also help minimize the risks to people, animals, and the environment and reduce the cost of pest control.
For instance, a fence and a motion-detecting light with a siren are simple but effective deterrents for pests such as deer that can cause significant damage to cabbage fields or vegetable gardens. In these situations, the landlord is normally responsible for providing pest control. In other instances, legislation such as the Prevention of Damage by Pest Act (1949) gives authorities the right to inspect a property and requires that owners maintain it free from pests.
