Pest Control Prosper TX is the management of unwanted organisms that harm plants or animals. It can be accomplished through exclusion, repulsion, physical removal or chemical treatment.

Preventative measures include removing food and water sources, reducing clutter, sealing cracks, and regularly cleaning dark, damp areas. Biological methods use living organisms such as predators, parasitoids, or pathogens to suppress pest populations.

Insects play many important roles in nature, including fertilizing plants and pollinating them. Some insects eat other insects, which helps reduce pest populations. They can also carry diseases that threaten crops and people. Moreover, their mouthparts can insert bacteria and viruses into plants. For example, thrips moving between impatiens and other plants could transmit mycoplasma-like organisms that cause Peach X disease or aster yellows. In addition, they can introduce plant pathogens that could threaten greenhouse-grown plants like gypsy moths and canker worms.

In general, insect populations fluctuate widely over time, influenced by weather and food supply. Thus, it is often difficult to predict how an infestation will develop. Insecticides can control these populations, but only when they are applied before damage occurs.

The use of insecticides must be balanced with the benefits that many insects provide to our environment. In fact, some insects are necessary for the reproduction of flowering plants. For this reason, many gardeners and farmers are reluctant to apply insecticides that might harm these beneficial species.

Insecticides should only be used according to the directions on their labels, and a great deal of care must be exercised when applying them around plants. All insecticides — even those labeled as “safe” for home use — can have negative impacts if used incorrectly. Legislation requires that labels give full directions for use, including proper safety precautions.

Because of the wide variations in cognitive abilities among insect species, any potential role for learning by parasitoids or predators should be examined on a case-by-case basis within a pest management strategy. Some hymenopterans, such as parasitoids of gypsy moths and cankerworms, have demonstrated the ability to learn by association between odor blends and host-plant species (Tully et al. 1994, Meller and Davis 1996).

In addition, a variety of physical barriers can be implemented to restrict the movement of unwanted insects. These include greenhouses, tunnels, and pesticide-treated barrier nets. A final note: the use of pheromone lures can help attract and control certain types of insects without exposing them to chemical agents that might disrupt their natural behavior.

Rodents

Rodents (including mice, rats, squirrels and hamsters) are a common pest problem. They can cause a wide range of damage, primarily by chewing. Their front teeth never stop growing, so they must chew on things to keep them trimmed, including wood framing and structural beams. This can weaken the structure of a building, leading to costly repairs and potential hazards for people living in the home.

They also contaminate food with their droppings, urine and saliva. They also gnaw on electrical wiring, which can lead to short circuits and fires. Thousands of people are bitten by rodents each year, and many of them become sensitized to rodent dander, which can trigger asthma.

Because rodents are so abundant, they can easily repopulate an area with their young, making control more difficult. A professional should always be involved in the process of rodent management, and a plan should include sanitation, exclusion and lethal controls.

Identifying an infestation early is key to avoiding significant property damage and other problems. Inspect your home and commercial buildings on a regular basis for signs of rodent activity. Look for droppings, rub marks, urine (using a black light) and nesting materials. Listen for scratching and other noises, and be sure to check out hard-to-reach places like behind stove walls and under sinks.

Preventing rodents requires removing their food sources and shelter. Store foods in rodent-proof containers, and remove piles of debris, stacks of lumber, trash and animal carcasses from the surrounding area. Trim trees and shrubs that overhang or touch buildings, and rake up leaves and debris that can provide shelter.

There are a number of rodenticide products available, including solid bait blocks, grain and pellet baits, and liquid baits. Solid baits should be housed in tamper-resistant bait stations, while liquid baits can be placed in areas inaccessible to children and pets. In addition, traps can be “pre-baited” without setting them to get rodents used to their presence and increase the chances of routine feeding and triggering the traps when they are set. These methods should be combined with ongoing sanitation efforts to achieve effective and long-lasting results.

Bed Bugs

The dreaded bed bug is perhaps the most challenging of all pests to control. These small, reddish-brown blood-sucking insects hide during the day in crevices and cracks of beds, furniture, wall moldings, and baseboards and come out at night to feed on people who sleep in infested rooms. Although they don’t spread disease, they can irritate people who are allergic to them. High standards of hygiene and housekeeping may help prevent or control infestations, but they cannot eliminate them completely.

The most effective method of eradicating bed bugs is to use heat treatment, which kills all stages of the pests, including their eggs. However, this treatment can take a full workday or overnight and requires the entire home to be evacuated. For this reason, it’s important to choose a professional exterminator who specializes in bed bug control and has experience with this problem.

A less-invasive alternative is to spray common hiding spots with surface pesticides that are labeled for bed bug control. This should include all furniture, draperies, carpets, mattresses, and box springs. Alternatively, a mattress encasement can be used to block the insects’ access to oxygen and food and suffocate them. These encasements, which are typically plastic and zippered, can be purchased online or from many pest control companies.

Another option is to place pitfall traps around a room’s furniture and beds, which intercept the pests as they leave or try to enter these resting places. Several studies have found that these traps are more effective than visual inspection at detecting low-level infestations, but they can’t replace a thorough inspection of the entire area.

Other options for managing a bed bug problem include washing sheets, pillowcases, blankets, and clothes in hot water and drying them on the highest dryer setting. Clothes that can’t be washed or dried should be sealed in plastic bags and placed outside for a few days in the sun. Bed bug swatters and insecticidal dusts can also be used in recessed screw holes, behind headboards, on furniture seams, under picture frames and clocks, and other hard-to-reach areas.

Weeds

Weeds cost farmers more than any other pest category, and many organic growers view them as their biggest barrier to successful organic vegetable production. However, while due vigilance to keep them from restricting crop growth is essential, a war mentality toward weeds can be counterproductive. Instead, organic weed control is best approached as a dance with nature to fulfill their natural ecological roles in the farm or garden ecosystem.

Weedy species such as lambsquarters (Quercus sativa) and wild carrot (Daucus carota) provide food for birds and mammals that prey on vegetable crop pests. Their flowers also supply nectar and pollen to the adult phases of beneficial insects and nematodes that assist with vegetable crop health. In addition, the stolons of perennial species like Phragmites (Phragmites australis) spread by seed and can help to stabilize soil erosion.

In contrast, annual weed species such as pigweeds and common ragwort (Rumex obtusifolius) are highly competitive in vegetable fields and require frequent disturbance to thrive. Because of their accelerated growth and prolific seed set, they are well adapted to cropping systems that frequently till or otherwise disturb the soil. This rapid growth, together with their high response to soluble nutrients and aboveground canopies that compete with crop plants for sunlight, enables them to rapidly establish in the disturbed soil.

The weedy characteristics that make them effective competitors in vegetable crops can also make them difficult to kill with herbicides. In fact, the long-term use of most herbicides has elicited an evolutionary adaptation from many annual weedy species, namely herbicide resistance.

As a result, many of the strategies used to control weeds in non-organic farming systems, including cultivation, mechanical and physical disturbances, and chemical spraying, have limited effectiveness against resistant weeds. Nontoxic methods of weed control, such as targeted application of classical biological control agents (herbivorous insects and microbial pathogens imported from the weed’s place of origin) and grazing by goats and sheep that devour invasive exotic weed species and their rhizomes, can be more effective in achieving a balanced, healthy weed flora in an organic production system.

Monitoring pests and determining when to begin control helps keep damage below damaging threshold levels. Correctly identifying the pest is important for selecting effective biological or chemical controls.

Denying pests food, shelter, proper temperature, and other basic needs reduces their numbers and damage. Physical and cultural practices can help manage pest problems, too. For more information, click Here.

Biological control uses living predators, parasites, disease pathogens or competitors to suppress pest populations and damage without the use of chemical pesticides. In general, these organisms are referred to as “natural enemies.” Biological control tactics differ widely depending on the target pest, environmental conditions, and pest life cycle. They are grouped into three general approaches:

Importation or classical biological control is where natural enemies from the target pest’s place of origin are brought to a new area, often in order to replace those that have been destroyed by natural selection or other factors. This is the approach most frequently used in greenhouses, nurseries and some fruit and vegetable fields to manage insect pests and weeds.

In some cases, a natural enemy is simply introduced to a crop when the population of the target pest is low. This is sometimes called delaying a pest’s attack. It can be effective against certain crops with critical windows of development (bud burst, flowering, etc).

A third approach to biological control is augmentation or “enhancing” existing populations of natural enemies in an attempt to increase their ability to suppress pests. Augmentation is most common in field crops such as grapes, tomatoes and squash.

The goal of augmentation is to increase the number or effectiveness of natural enemies in an area by mass-rearing and/or releasing them in large quantities. This is most often done in the form of pathogens, but also includes predators and parasitoids.

Biological controls are most effective when used as part of a multifaceted Integrated Pest Management program. Biological control tactics can help reduce the amount of chemical pesticides used, especially in the home landscape, and provide valuable ecosystem services such as soil fertility improvement. They can also be used to supplement other control strategies, such as the introduction of herbicide resistant crops, genetically modified plants, pheromone disruption techniques and botanical insecticides.

To maximize the benefit of biological control, gardeners should be aware that natural enemies are living organisms with their own needs. To encourage them, gardeners should provide suitable habitat, including a variety of plantings that the natural enemies will find attractive and a water source.

Chemical Management

Chemical pest control involves using substances that kill or repel a pest population. The term pesticide covers a wide variety of compounds, including herbicides that kill plants, insecticides that kill insects, fungicides that kill fungi and rodenticides that kill rodents. The majority of chemicals are synthetic, but some natural organic products can also be considered pesticides. All pesticides must be carefully selected and used according to the label instructions in order to reduce risks to people, pets and nontarget organisms that may be harmed by the chemicals.

Chemicals that work by poisoning a pest have roots in history that stretch back centuries. The use of lime, wood ash and nicotine was common in the 1600s, while arsenic and mercury were popular options during the 1920s. Synthetic chemical pesticides became more popular with the advent of DDT in the 1930s, but issues with safety and environmental damage caused by misuse quickly emerged.

Modern chemical pest control treatments are designed to be safer and more environmentally friendly than ever before. With low-dose options and strict safety standards, they can be an effective last resort for many difficult pest infestations. They are categorized as plant protection products in the United States and must be registered for each use.

While physical methods of pest control can provide a more immediate solution to pest problems, they do not offer long-term results and may require significant staff resources to maintain. In addition, they are less reliable than chemical options in controlling a pest problem once it has started.

Biological pest control methods are often more effective than chemical options in reducing a plant-feeding insect population and can be applied to large areas. However, they can take much longer to produce results and are often more expensive.

While there are a wide variety of biopesticides, the most commonly used biological agent is bacillus thuringiensis (Bt). This bacterium produces a toxin that kills caterpillars by destroying their midguts. It can be found in a variety of formulations and works against over 400 different insect species without harming humans or pets.

Physical Management

A physical approach to pest management involves blocking access to food and water, excluding pests from areas and eliminating hiding places. This can be done through trapping or the use of barriers such as fences, screens and other material. Pests can also be repelled by chemicals, such as attractants or predators, or by sound and visual devices. Physical controls can also include sweeping up or vacuuming pests from surfaces and in storage areas. The physical aspect of pest management can also involve ‘pest proofing’ facilities by sealing openings, installing doors with tight-fitting hinges and using other materials that prevent entry or exit of pests.

The first step in any pest management program is accurate identification of the pests to be controlled. This is important because a pest’s characteristics affect its behavior and life cycle, and how it responds to control methods. Knowing the pest’s preferred foods, water sources and habitats, for example, can reveal weaknesses in its population that may be exploited.

Once a pest is identified, monitoring must begin. Regular inspections of the area where the pest is found are essential to discovering and correcting conditions that favor it. A flashlight is useful for checking dark or secluded areas where the pest hides, and a magnifier is helpful in identifying insect parts and frass (excrement). Frequently inspected spots should be recorded and any unusual findings should be noted.

An important part of this monitoring is to determine the level of damage that is unacceptable. This level is called a threshold and must be established before any action is taken to manage the pest. Once a threshold is established, it can be used to select the best chemical, biological or physical control method.

Some pests are continuous and require continuous management. Others are sporadic or cyclical and need to be managed only periodically. Many pests are also resilient and adaptable, surviving or even increasing in numbers when conditions are favorable for them. Therefore, a successful pest management program must incorporate all methods of control to achieve sustainable results. This requires an integrated approach known as Integrated Pest Management (IPM). It is an approach that uses information about pests and available control methods in a way that minimizes risks to people, property and the environment.

Integrated Pest Management (IPM)

When pests occur, IPM uses a combination of preventive and curative actions. It begins with monitoring plants for signs of pests and then identifies the specific plant species or genotypes being attacked by those pests. This information is then used to determine the most effective control measures for that particular pest. IPM plans take into account a variety of control options including chemical, biological, and cultural methods. The goal of an IPM plan is to suppress pest populations below the point where they cause economic injury to a crop or landscaped area.

The use of IPM methods is often more environmentally responsible than the application of single-use chemical pesticides. It also helps to minimize resistance development by introducing more than one type of control method into the environment. The diversity of control strategies creates balancing selection pressures that retard the evolution of resistant pests.

Biological management is another component of IPM, and includes predators, parasitoids, and disease organisms that are naturally occurring in a field or garden ecosystem. For example, the flies that attack millipedes and grubs in a lawn or vegetable garden are natural enemies of these pests and help keep their numbers low. Likewise, natural predators and diseases that attack crop-feeding insects or mites also help to regulate pest populations.

Other forms of biological control include the use of pheromones, which mimic the hormones produced by a plant to communicate with pollinators. Similarly, soil fumigants, which contain volatile organic compounds that are toxic to pests, are an effective and non-chemical means of controlling pests.

A common strategy today to avoid resistance development is the use of multiple pesticides in a rotation or mixture. However, a recent study shows that this strategy may not be as effective as originally thought and should be reevaluated. An increasing emphasis on in-field genetic diversity, both in space and time, could be a good way to decrease resistance development as well. This would involve incorporating genetic variation into plant breeding programs for IPM purposes, as well as promoting diversity through crop and cultivar rotations. Ideally, these efforts would be done in concert with other elements of Evolutionary IPM such as the judicious use of pesticides.
