Pest Control Chesterfield MO methods vary depending on the environment and the constraints of the structure or building. These can include a chemical application, physical exclusion or the removal of material to address an issue.

Chemical solutions are typically easier to apply and deliver instant results. These can include repellents that prevent pests from approaching and insecticides to kill existing pest populations.

Insects are the most numerous and diverse animals on earth. They make up more than half of all animal species described by science. Some insects, including ants, bees, wasps, butterflies and moths, serve useful purposes, while others harm people and plants. Some pests bite or sting, spread disease and damage crops and plants.

In the agricultural field, pesticides are used to control pests that threaten the health and productivity of plants and crops. A good starting point for any pesticide program is the proper identification of insect and other arthropod species that need to be controlled. Proper identification is necessary for accurate timing and dosage of pesticides. It also helps in the selection of a suitable pesticide to use and the correct method of application. It is especially important to be able to identify insects that are not pests, such as beneficial insects, so that they can be left alone.

Grasshoppers, beetles, caterpillars and other insect species that chew their way through leaves, stems and fruit are considered pests of gardens and crops. They often leave holes in plant tissue and a trail of excrement as they feed. In some cases, the chewing of plant tissue may cause discolored spotting or pimples on the surface of a plant.

Pesticides are used to control these and other pests that damage plants or damage structures. Pesticides must be applied in a timely manner so that the plants have an opportunity to absorb the needed nutrients before the pests devastate them. In many instances, it is easier to control the pests by using an insecticide during the nymphal stage of their life cycle, just after they hatch from eggs. This is because the nymphs are small and difficult to see without a magnifying lens, unlike the adult insects that can be seen easily with the naked eye.

Insects that go through the pupal stage, such as stink bugs and squash bugs, have piercing mouthparts to “suck” juice from plant leaves, stems and fruit. These are common pests of tomatoes, beans and squash and can cause discolored spotting and pimples on the surface of these crops.


Rodents are a nuisance to humans, causing damage to structures and crops. They also carry diseases that affect people, pets and livestock. They chew through wires, pipes and other materials causing fire hazards. In addition, rodents urinate and defecate everywhere, ruining food and items stored inside homes. They can even tear up important paperwork and destroy family heirlooms.

Rats, mice, squirrels, voles and rabbits belong to the order Muricidae (Muridae is Latin for gnawing teeth). They are found in almost every terrestrial habitat on Earth, including human-made environments. They are diurnal or nocturnal and live in burrows, trees, waterways, on land or at sea. They are opportunistic feeders and predators of both invertebrates and vertebrates. Rodents have two pairs of ever-growing incisors, and many species are either herbivorous or semi-carnivorous, and can eat both plant and animal matter.

While a variety of rodent control methods are available, prevention is the best approach. Proper sanitation of indoor and outdoor areas can reduce the need for rodenticides. This includes storing foods in containers made of materials hard for rodents to chew, and keeping woodpiles and stacks away from the structure. Trash should be disposed of frequently, and garbage bins should have tight-fitting lids. Insecticides can also help prevent rodent infestations.

Despite best efforts, rodents may still enter buildings and other structures through small openings such as cracks, crevices and gaps. Doors should be kept closed and cleared of debris, and thresholds should be sealed to prevent rodents from climbing through them. Exterior vents should be covered with grates that exclude rodents. Floor drains should have screens to keep rodents from entering and climbing in. Gutters should be checked regularly, and water should not stand around air-conditioning units or in sinks.

Grass should be cut short, and brush and dense shrubbery trimmed to prevent rodent shelter and feeding sites. Buildings should be adequately insulated and weatherized, and insulation in roof cavities should be replaced as necessary. Woodpiles and stacks should be placed where they cannot be accessed by rodents, and lumber should be stacked at least 12 inches off the ground and away from structures.

Poisonous Animals

Animals that produce toxic secretions, known as poisons or venoms, are found in virtually every phylum. These substances serve a variety of purposes, from prey capture to predator deterrence. They may act directly through the tissues of the animal (e.g., ciguatoxin accumulation in predatory fish) or they may be delivered through the mouth (snakes) or expelled into the surrounding environment (cone snails).

Although snake envenomation has a negative public image, these creatures are essential to pest control. Without venomous animals, humans would be overrun by innumerable insects and other arthropods. The humble European mole, for example, uses a toxin in its saliva to subdue earthworms before digging up the garden.

Pest Control Technicians

Pest control workers use a variety of methods to eliminate bedbugs, ants, termites, rodents and other unwanted insects or animals. Their job duties include assessing an infestation, treating affected areas and providing preventive maintenance at homes or commercial properties. They often need to interact with clients and may describe treatment processes or recommend follow-up measures. Some technicians specialize in certain types of pests or techniques, while others receive more general on-the-job training. A high school diploma or equivalent is usually the minimum requirement for most positions.

Pest controls workers frequently work outdoors and indoors in all weather conditions. They may need to cut or bore through walls to access infested areas, make minor exclusions and set mechanical traps. They also spray or dust chemical solutions, powders or gases to kill or repel pests from buildings or outdoor areas.

Technicians also need to maintain their company vehicles and equipment, and keep records of client interactions and service visits. They should be familiar with the Environmental Protection Agency’s guidelines for applying pesticides and should be able to operate power sprayers, foggers, pumps, drills, vacuums and other basic hand tools.

In addition to the physical demands of the job, pest control workers should be comfortable working in small spaces and confined areas where insect or rodent droppings may accumulate. They should be aware of potential health risks from exposure to pesticides, as well as other substances such as feces or urine. They should wear protective clothing and use personal safety equipment such as gloves, goggles and respirators as necessary.

Keeping accurate records is important for pest control technicians, as they must document their treatments and submit them to managers or supervisors. They may also need to fill out paperwork such as a pesticide application report or other documentation required by state or local agencies. They must be able to identify the type of pest and its behavior, as well as any conditions or environmental factors that might have contributed to the infestation. This information can help managers determine whether additional services are needed. This is especially crucial if the pests have caused structural damage or public health concerns, such as gnawed wires that could create fire hazards or disease-causing bacteria such as salmonella, leptospirosis and hantavirus.
