Pest Control involves removing food, water, and shelter sources for unwanted organisms. This may include rodent traps, baits, and lethal sprays.

In outdoor pest situations, eradication is rarely the goal; instead, suppression and prevention are common goals. Contact Nature Shield Pest Solutions now!

Pests can damage your property (like rats, bees, and ants) or harm you physically or psychologically (like bed bugs and cluster flies). Professional pest control companies are trained to deal with these invaders.

Accurate pest identification is the first step in a successful pest management program. Proper identification enables you to understand the pest’s life cycle, food requirements, habitat and harborage preferences, and behavior. This information will help you to select an appropriate management action. For example, identifying the specific pests that are damaging your collection will help you to choose the best way to control them without using harmful chemicals.

Pest identification may seem simple enough, but it is important to remember that pests can look very similar to each other or even to non-pests as they progress through their life stages. An immature beetle, for instance, might resemble a caterpillar or worm. Also, different types of damage can be caused by the same insect species. For this reason, proper identification requires careful observation and comparison with published descriptions and images.

When attempting to identify a pest, consider shape and size, color, number of legs, wings or antennae, as well as the presence or absence of any sucking mouthparts, spiracles or sucking feet. Insects’ stings and bites can also be useful indicators of identity, as can the presence of egg sacs or pupal skin. In addition, observe whether the pest has a distinct odor, as is often the case with fruit flies and cockroaches, or staining, wrinkling or discoloration of the damaged plant tissue, as in the cases of beetles and leafminers.

If possible, try to identify the pest to the order level. This is helpful when selecting an appropriate biological insecticide. For example, a product that is labeled for the control of lepidoptera (caterpillars) will not be effective against chrysanthemum leafminers.

If you are still not sure what kind of bug or pest you have, contact your local entomologist or MMPC’s free Pest ID Center. The experts at the Pest ID Center will analyze a physical specimen or an image of your mystery pest and provide identification results and suggestions for treatment. For more information, see the Pest ID Center’s Frequently Asked Questions. Alternatively, you can consult the MMPC Insect and Pest Identification Guide.

Pesticides

Pesticides are chemical substances used to kill or prevent the growth of harmful organisms such as insects, diseases, weeds and rodents. They can take a variety of forms, such as solids, liquids, powders or sprays. Their toxicity is determined by the chemicals that comprise them and their mode of action. The Environmental Protection Agency regulates and monitors the use of pesticides by sponsoring research, conducting inspections, publishing information, and educating the public.

The primary advantage of using pesticides is to save crops from insect infestations or damage. Other uses include controlling disease vectors that carry human and animal pathogens or nuisance organisms that disrupt human activities and structures. Many pesticides contain “inert” chemicals, which are used to stabilize the formulation and allow it to perform its intended function. While the majority of these chemicals reach their target, a significant percentage also end up in air, water and sediments or even in our food. The health impacts of these chemicals range from acute effects that occur at high levels for short periods of time to chronic exposures over long periods of time and may include cancers, birth defects and preterm delivery, reproductive harm and immune system disruption.

Pest control products are regulated by the Environmental Protection Agency (EPA) in the United States and each state government has its own review process for pesticides. Typically, the EPA will approve a pesticide and then each state will register it. A pesticide can be classified by schedules that determine how toxic it is and how it will be used, as well as the form it takes, such as a solid, liquid or powder.

A pesticide can be used on a single plant or an entire field, in a greenhouse or in the open. It can be applied by a ground or aerial equipment and can leave behind residues on the plant, in the soil or in the air. These residues can be blown into nearby homes, schools and businesses, where they may be inhaled or ingested. They can also be washed into ponds, rivers and streams where they may affect the habitat of aquatic organisms and enter our water supply.

Biological Control

Biological control is a pest management strategy that uses natural enemies to reduce populations of a target pest, rather than spraying chemicals. Biological control can be more complex and expensive than chemical control, but it is environmentally sustainable and generally more effective. It requires a deep understanding of the ecology and behavior of both the pest and its natural enemies, and must be designed and put into action in ways that are compatible with the natural enemy’s natural environment and life cycle. Biological control of insects, weeds and plant diseases is a critical component of integrated pest management.

Unlike synthetic pesticides, which can harm both natural enemies and beneficial microorganisms, the use of biological agents usually does not harm other organisms in the environment. However, some biocontrol agents (such as bacillus thuringiensis or Bt, entomopathogenic nematodes, and parasitized flies or syrphid fly larvae) can be toxic to natural enemies when used in excessive amounts or under poor conditions.

The simplest type of biological control is called classical biological control, and involves the importation of natural enemies from their native habitats to control an introduced pest. This is a common technique for controlling exotic insect pests, such as the cottony cushion scale on orange trees or the invasive alligator weed. Researchers study the pest’s native habitat, and search for and collect indigenous natural enemies that kill the pest. The promising natural enemies are then shipped back for testing and possible release in the area where the pest is found. Several successful examples of classical biological control have been recorded, such as the introduction of Rodolia cardinalis, the vedalia beetle, to control cottony cushion scale on citrus trees, and Hippodamia convergens, the convergent lady beetle, to control aphids on vegetables.

Another type of biological control is augmentation, which seeks to increase the effectiveness of naturally occurring predators, parasitoids or pathogens that already exist in an environment to better suppress a particular pest. This is accomplished through either mass production in insectaries, or through periodic augmentation of the natural enemy population at the field site, through inoculative or inundative releases. Augmentation is typically more effective for certain pests than others, as many biocontrol agents are host-specific. The predatory mite Amblysieus swirskii, for example, feeds on several species of thrips and whiteflies, while the fungus pathogen Phytoseiulus galleriae is effective only against grubs.

Prevention

Pests are organisms that damage or interfere with human activities, crops, livestock, plants, or the environment. They can also spread disease to humans, animals, and crops, contaminate food or water supplies, and destroy property. Pest control involves preventive and curative measures to keep populations below damaging levels. Pesticides are often used for control, but other methods may be employed as well.

Prevention involves practices that deter or remove sources of food, water, and shelter for pests. These include avoiding clutter that provides hiding places, sealing cracks and openings, and keeping garbage receptacles tightly closed and cleaned.

Early warning signs of pest infestations can help detect them before they cause major problems. For example, termite activity can be detected by the faint, hollow sound of wood when tapped, and by mud tubes on exterior walls that lead to nests. A professional pest control company can assess a building and implement preventive strategies tailored to that specific site.

Identifying and correctly identifying pests is essential to determining whether they can be tolerated or need to be controlled. Incorrect identification can lead to over-reliance on one type of management strategy or the indiscriminate killing of beneficial insects and organisms that provide natural pest control.

A well-rounded approach to pest control integrates biological, cultural, and mechanical methods and uses pesticides judiciously. This includes adjusting the use of pesticides according to monitoring results and the local environment. It also requires education and awareness to increase understanding of pest behaviors and ecology.

The goal of prevention is to achieve an acceptable level of pest damage without causing unacceptable harm to humans, property, or the environment. This is a difficult goal to accomplish, especially in agricultural settings where pests are an inevitable part of the landscape.

Pest control is a vital part of protecting public health by controlling diseases that pests carry, safeguarding agriculture and food supplies, preserving buildings and their contents, and maintaining ecological balance. While there are times when pests must be controlled, the best and most economical way to do so is through preventive pest management.

Pests include small mammals (such as mice), crawling insects (such as ants and cockroaches), and flying insects (such as houseflies, fermentation flies, and moths). Parasitic nematodes are also helpful pest control tools.

Pests can cause a wide variety of problems. They can damage property or spread disease to people and pets. They can also interfere with the function of facilities such as hospitals, schools, and food processing plants. In most cases, the best way to manage pests is to prevent them from entering buildings in the first place. This can be done by creating sanitary environments through routine cleaning and storage practices. Infestation prevention should also include identifying and sealing entry points.

For example, rodents and other pests often enter homes through open doors and windows, so these should be closed as much as possible. Clutter around the house should be removed, and shrubs and tree limbs should be trimmed away from the house to prevent pests from accessing it. Moisture sources should be addressed, as well. Pests often thrive in damp conditions, so fixing leaks and removing standing water should be a priority.

Other preventive measures include managing waste properly and securing garbage containers. This will help prevent pests from getting into the trash and breeding inside it. Regularly vacuuming and wiping down surfaces will help eliminate food residues that attract cockroaches and other insects. Store foods in sealed containers, and always wash produce before consuming it. Cracks and crevices should be caulked to make it more difficult for pests to gain entry into a home or building.

Preventive measures are not enough to keep some pests out of a building, so they need to be augmented with suppression and/or eradication strategies. Suppression involves reducing the number of pests to below an unacceptable level through targeted applications of physical, biological, or chemical techniques. It may be necessary to spray rooms with pesticides, but only after a careful assessment of the situation and consideration of all alternatives.

Eradication is a rare goal in outdoor pest situations, but it is occasionally attempted for certain problem species such as Mediterranean fruit fly and gypsy moth. In indoor settings, eradication is more common because pests can be controlled more easily than in the open. Pests infesting a hospital, school, or restaurant are not only a nuisance, but can threaten people’s health. Rodents can carry and transmit diseases such as Salmonella, and flies can spread gastrointestinal infections including Shigella and Hepatitis. In addition, the presence of pests can lead to closure of a facility until the problem is managed.

Suppression

Pests can cause serious damage to the environment, agriculture, livestock and homes. Proper management helps control them to prevent harm. There are a number of techniques to control pests, including natural, biological, and chemical controls. Some controls influence the environment and limit populations, others kill them directly or change their ability to reproduce. Some also alter the amount of water, light or heat available. These include physical and mechanical controls, agrochemicals, and cultural practices.

Weather, topography and habitat factors limit the population of many pests by influencing their growth, development, and feeding habits. Predatory birds, fish, mammals and reptiles feed on or parasitize some pest insects, reducing their numbers. Insect-like mites, nematodes and pathogens also suppress some pests by injuring or killing them or by blocking their ability to reproduce.

Agricultural and residential sanitation practices help prevent pest infestations by eliminating their food, water, or shelter. Proper trash disposal and frequent garbage pickup reduces pest harborage. Sanitation practices also prevent the spread of some pests between fields or yards by removing crop residues, and sterilizing equipment and materials before moving to a new area.

Some agrochemicals are designed to kill or prevent the reproduction of specific pests. These include insecticides, herbicides, and fungicides. The choice of a chemical depends on the type and severity of the pest problem, the effectiveness of other control measures, and the environmental effects of the different chemicals.

Agrochemicals should be used with care because some have the potential to harm the environment, humans or beneficial organisms. They should be applied only to areas where they are needed, and used in ways that minimize the chance of them transferring to non-target organisms.

Many pests are attracted to bright lights or colors. Traps, barriers and screens can be used to keep them away from crops, homes or structures. Some devices emit pheromones that confuse or repel male pests, lowering their numbers. Juvenile hormones can likewise be used to decrease pest numbers by preventing them from maturing into adults that can produce offspring. Other agrochemicals, such as fungicides and plant growth regulators, are used to improve the quality of fruits, vegetables or flowers.

Eradication

The goal of eradication is rarely achieved in outdoor pest situations, where prevention and suppression are more common. However, eradication can be an important part of pest control in enclosed areas such as dwellings; schools and offices; and health care, food preparation and processing facilities.

Eradication involves destroying the entire population of a pest species to prevent it from reproducing. This may be accomplished through a combination of physical, biological, or chemical means. Physical methods include traps and netting, while biological methods involve the use of natural enemies to disrupt pest populations. Chemical methods typically employ pesticides, which kill the pests through direct or indirect application. These chemicals can be very effective, although they also pose risks to human and environmental health when used improperly.

Regardless of the method employed, a pest problem should be addressed as soon as possible. Many pests carry diseases that can affect humans and animals. Some may even cause damage to property or crops. Pest infestations can be difficult to eradicate because of the persistence and adaptability of some species.

Pests are attracted to moist and sheltered areas, so it’s important to eliminate sources of moisture. In homes, this might mean repairing leaky pipes and sealing cracks and crevices. It’s also a good idea to remove standing water and dead vegetation around the home.

A clean environment is also a deterrent to most pests. Regular vacuuming and sweeping, the removal of clutter, and frequent garbage disposal are all effective ways to keep pests away. The most effective cleaning strategy, however, is to implement a routine that prevents future pest infestations before they occur.

Eradicating pests requires time and effort. While preventative treatments are relatively quick, eradicating existing infestations can take several hours or longer. Eradication should be a comprehensive process, involving both killing existing pests and blocking their entry into the area in question.

Monitoring

Monitoring pest control activities is an essential part of Integrated Pest Management (IPM). It helps you determine when action is needed and assess how effective your tactics are. Ideally, you want to treat only for pests that have reached unacceptable levels and have been identified through monitoring.

Monitoring can be done using a variety of traps and other devices that attract or capture specific pests. This includes sticky boards, electronic fly traps, moth pots and pheromone traps. The traps or monitors should be checked on a weekly, monthly or quarterly basis depending on your level of infestation. Each time, the device should be cleaned and rebaited if necessary. A log should be kept to track and report the results of each monitoring session.

When monitoring, it is important to know your crop and its life cycle. This will help you identify and interpret the results of your scouting efforts. You should also be aware of critical crop development stages so that you can concentrate your monitoring at times when the crop is most susceptible to damage. For example, pulse crops may require scouting weekly during the vegetative stage and twice a week from budding onward.

During your inspection, note the number and type of pests you find as well as the amount of damage or other symptoms. Record this information in a pest identification log or similar data collection system. Also, note where you found the pests and their behavior. This will allow you to track the movement of the pests and understand how they are interacting with your crops.

A flashlight is an invaluable tool to carry during inspections because many pests live or seek shelter in dark harborage areas, such as crevices and corners. An extendable mirror is also useful to inspect behind and beneath equipment and furniture. It is recommended that you carry a magnifying glass to help identify the pests and their corresponding frass (excrement) and to confirm the presence of their damage.

Keeping up with regular maintenance and sanitation can prevent pests from becoming a problem in the first place. Routinely cleaning shelves, equipment and drains can reduce the moisture content of your facility, making it less attractive to pests. Screening and caulking can keep pests out of buildings and other structures. Physical exclusion is an important strategy for health care facilities. It involves removing any points of entry, as well as identifying and prioritizing needed repair work to minimize the risk of a pest invasion.
