Pest Control: What Are the Most Common Insects on Earth?

Pest Control involves preventing and managing unwanted organisms that damage plants, animals, structures, or property. This can be achieved through exclusion, repulsion, physical removal, or chemical control.

Preventive measures include removing food and water sources, closing off hiding places, and repairing cracks. Generally, low-risk pesticides can be used when necessary. Contact Pest Control Tarzana now!

There are more than five million extant insect species. They are the most successful land vertebrates, occupying a wide variety of niches not exploited by more earthbound animal groups.

Insects obtain their food by living in or on plants; eating pollen, seeds or fruit; piercing leaves and stems for sap; and attacking other insects. Some insects transmit diseases to plants such as peach rust and tomato spotted wilt, and others, like western flower thrips, can devastate crops growing in greenhouses.

Insecticides are applied to homes and gardens, golf courses and lawns, cropfields and forests for control of many different pest insects. Most are toxic to natural enemies such as predators and parasitoids. The effectiveness of an insecticide depends on how, when and where it is used, as well as on weather conditions.

Rodents

Rodents are global pests that can cause serious damage and economic losses. They are a major food source for predators and carry numerous diseases. They also contaminate food and spread fires by chewing on electrical wires.

Rodents live in and around structures for warmth, water, shelter and food. Depending on the species, they can cause significant damage. Signs of a rodent problem include droppings, pilfered food, gnaw marks and grease spots.

Reduce attractants with sanitation and exclusion. Store foods in rodent-proof containers, such as metal or heavy plastic and keep kitchens, common areas and garbage areas clean. Keep trees trimmed and inspect regularly for signs of rodent activity. Use nontoxic monitoring bait blocks in tamper-resistant stations and place glue boards or snap traps in vulnerable locations such as wall voids, custodial closets and vending areas. Use lower toxicity products first and only resort to rodenticides when all other methods have failed.

Rodent Control

Rodents breed incredibly quickly and must be controlled to protect people and property. Their gnawing habit can cause significant damage to woodwork, insulation, wires and other parts of the structure of your home or business. This can lead to electrical outages, fire hazards and other expensive repairs.

They also carry pathogens that can cause diseases in humans like Hantavirus and Salmonella. Regular inspections for droppings and signs of rodents can help reduce the risk of disease.

Rodent control includes removing food, water and shelter attractants by sealing containers, eliminating loose trash, cleaning up debris and preventing access points by securing doors, windows, vents and entry points. It also involves visual inspections to identify and eliminate entry points (mice can squeeze through openings the size of a dime, while rats can contort their bodies into spaces as small as a quarter). Placing nontoxic monitoring bait blocks in tamper-resistant stations helps prevent rodent populations from increasing.

Mosquitoes

Mosquitoes are among the most intensely studied insects on earth, and for good reason. They are responsible for transmitting deadly diseases like malaria, dengue, chikungunya and yellow fever to people and animals.

There are over 3,500 mosquito species, but only a few spread disease to humans. Most mosquitoes are nuisance pests that bother us when we’re out enjoying the great outdoors, but some species carry dangerous germs that can make you sick.

Most mosquitoes develop in water, and removing all breeding sites on a property is an effective way to control mosquito populations. For larger properties, implementing integrated mosquito management methods including source reduction and targeted insecticide application with fogging products can help prevent mosquito-borne disease outbreaks.

Bed Bugs

Bed bugs are a growing problem in homes, apartments and hotels. They are primarily active at night and hide in dark cracks and crevices during the day. Although they prefer human hosts, nymphs and adults will readily hitch rides to other dwellings where they can feed.

Infestations in multi-unit housing are more challenging to control since residents may unknowingly transport the pests from home and between units. Routine, building-wide inspections and treatment are essential.

Extensive prep is not always needed in light infestations, as long as bedding and upholstered furnishings are removed. However, clutter often must be removed to allow treatment of the seams, folds and creases where the bugs reside. Proper application of approved pesticides is critical. Improper use can result in severe health and environmental risks. Be sure to follow product label instructions carefully.

Fleas

Fleas are a common pet problem and can be a major health risk for pets and people. These bloodsucking pests spread disease and can cause intense, itchy bites that make humans and pets scratch excessively.

Pest control technicians can use insect growth regulators (IGRs) to stop normal flea life cycles. They can also treat animal pens, dog houses, crawl spaces, lawns, and other areas that pets rest in the summer with spray treatments. Thorough vacuuming and washing of pet bedding are recommended after treatments. Daily vacuuming post-treatment will help eliminate new fleas as they emerge from the pupal stage and start biting.

Beetles

If an alien civilisation was trying to understand how life works on Earth, it could do worse than study beetles. These insects are prolific and adaptive, living everywhere except the oceans and polar regions.

Beetle larvae eat anything, and adult beetles have a wide range of diets too. Some species, such as the lily beetle (Lilioceris lilii), are pests of garden plants, while others, such as carpet beetles and weevils, attack crops. Other beetles eat wool, fur, leather book bindings, feathers, animal skin and taxidermy mounts.

Some beetles are important predators of other insects and do valuable clean-up work, removing dung and breaking down dead organisms. Other species, such as the elm leaf beetle (Elmodium elegans), defoliate trees and can have economic impacts. Your PMP may recommend pheromone-based traps or low toxicity products to control beetles.

Wasps

Although they can be annoying, wasps are important pollinators and pest control agents. Their diet includes both nectar and insects, so they can effectively prey on a wide variety of pests in gardens, farms and urban areas.

Wasps can sting when provoked. This includes handling or swatting their nest, but even walking by an active wasp’s nest can prompt it to send a signal for reinforcements.

If you have a large wasp’s nest on your property, contact a pest professional for advice on how to remove it safely. This usually involves using insecticides formulated for wasps, available in commercially prepared, pressurized sprays or conventional pump-type, compressed air sprayers. Follow the label directions carefully to avoid toxicity. Ideally, the nest should be eliminated at night when wasps are less active. If this is not possible, use a flashlight with a red filter (wasps cannot see red light) to observe the nest opening and direct the spray at it.

Ants

Ants are one of the most widespread insects and are often nuisance pests indoors. They can invade homes, hospitals, offices and warehouses in search of food, water or shelter. They also protect and care for honeydew-producing plant pests such as aphids, soft scales and whiteflies, increasing crop damage.

Ant colonies communicate through chemical pheromones. Workers that forage for food or to repair the ant mound leave chemical trails that guide other ants to the location of their activity.

Barrier, perimeter and direct insecticide treatments of ant mounds are effective when done correctly. This is best achieved with long-residual broadcast contact products, such as granular fipronil (TopChoice G/Quali-Pro). Using these products in conjunction with other treatments such as the Two Step Method can increase control and reduce costs. Field size, ant exposure time and crop system influence ant-plant and ant-natural enemy interactions and plant damage.

Wasp Nests

If you have a wasp nest on or around your property, it is crucial that it be dealt with promptly by a pest control specialist. Many people are allergic to hornet or wasp stings, and multiple stings can cause a systemic reaction.

Wasps typically make their nests in sheltered locations like the eaves or porch ceiling, but they can also make them in attics. These types of nests are called paper wasp nests, and they are made from chewed wood fibers mixed with saliva. In each cell of a new nest, the queen lays an egg that eventually hatches into a larva. The larva feeds on sugary substances and catches insects until it goes through five moults and pupates into an adult wasp.

Removing a paper wasp nest is usually done at night to avoid foraging wasps from leaving the nest immediately after removal. This minimizes the risk of a rapid population loss due to manipulation stress.

Pest Management

Pest Management involves a series of actions to reduce the impact of unwanted organisms. It starts with defining pest management objectives and monitoring results.

Inspection and monitoring involve identifying and counting pests, estimating their numbers, and checking the damage they cause. They also include examining environmental conditions that promote or support pests, such as food availability, habitat conditions, and soil moisture levels. Contact Armis Pest Management now!

Integrated Pest Management (IPM) is an environmentally friendly, common-sense method of controlling pests that uses non-chemical methods and only resorts to chemical measures when necessary. It also limits the amount of pesticide used to prevent an infestation and keeps pesticide use to acceptable levels. IPM programs promote nature protection and sustainable agriculture in the long run.

IPM starts with monitoring a field, garden, building, landscape or other site for pests and considering their impact on that area. Scouting is an important part of the process to identify the type and number of pests and assess the damage they cause. A treatment strategy is then developed and implemented, taking into account the life cycle of the pest and how the environment impacts its development. This includes considering what natural enemies may be present and what weather conditions are expected to influence pest activity. An action threshold is determined and used to decide if pests are at a level that requires intervention.

Prevention methods reduce the need for pesticides. These include crop rotation, planting pest-resistant varieties and preventing water runoff from fields or other areas that can create moisture problems. Non-chemical controls also include removing food sources and other attractants to the pests, reducing the availability of water or sunlight, and applying physical or biological controls.

An IPM plan also incorporates economic benefits unrelated to the pests. For example, a crop rotation system can save money by reducing fuel and fertilizer costs. And a weatherization program can lower energy bills and help prevent moisture problems that attract pests.

IPM can be implemented in any facility, from homes to offices, hospitals and schools, and it can work for a wide range of pests. It is a process that considers all tools and strategies to determine appropriate pest levels and tolerance thresholds, and then integrates biological, cultural, mechanical and physical and chemical tools in a manner that minimizes health, environmental, economic, and human risks. To implement IPM, a facility must create and maintain an IPM plan, train staff in pest identification and management, and have at least one person trained to apply the chemical controls that might be needed.

Biological Management

Natural enemies such as predators, parasitoids and pathogens can reduce pest populations to levels below economic damage thresholds. This can eliminate the need for broad-spectrum chemical insecticides, which may affect non-target insects and beneficial organisms as well. Biological control methods are based on three principles: only living agents can mediate biological control, a biological control agent must always target a specific pest, and the impact of a biological control agent is limited to the target crop only.

Conservation biological control is the practice of conserving existing natural enemies in production systems. Many growers employ conservation tactics in their field operations, for example releasing beneficial insects (lacewings and lady beetles) to control aphids or planting cover crops or weedy borders to support parasitoid activity.

In classical biological control, researchers collect a natural enemy from its native habitat and introduce it to its new home, where it is expected to establish a sustainable population that will limit the growth of the target pest. This method has been successful in establishing permanent population limits for a number of crop pests, but it is less effective against exotic species and often fails to control established pests, especially native insect pests. Biological control requires significant initial investment to purchase and rear the natural enemy, but once it is established in a new environment it can be very low cost and does not require any further input from humans.

Augmentative biological control involves supplemental releases of natural enemies to achieve pest suppression. For example, large numbers of entomopathogenic nematodes (Trichogramma) are released on a regular basis to control several soil-dwelling insect pests in vegetable and field crops. The use of a natural enemy in this way is also known as inundative release, and the supplemental release can be carried out on a seasonal or periodic basis. The supplemental release of a natural enemy can also be used in conjunction with modification of the cropping system to provide additional shelter or food for the pest, a tactic that is called habitat manipulation.

While there are several important considerations to take into account when implementing biological control, a good program can result in the replacement of chemical pesticides, which can have adverse environmental and human health impacts. However, it is important to remember that biological control only controls pests when it is part of an integrated IPM approach. Other pest management tools include resistance varieties, cultural practices that reduce pest abundance or damage, and methods of manipulating pest mating or host-finding behavior.

Physical Control

Unlike pesticides, which kill the unwanted organisms directly, physical controls interfere with the environment and/or life cycle of the pest. They are most often used to prevent pest populations from reaching damaging levels. Barriers block pests from reaching plants; traps, such as snares for rodents, or netting for fruit trees keep birds and insects away from the crop; and mechanical methods like weeding, hoeing, mowing and cultivation destroy weeds and prevent their seedlings from germinating.

Biological control is the use of natural predators, parasites and disease organisms that ordinarily occur in nature to reduce the population of pests. This approach is effective for many plant pests, and it is usually safer to use than chemical methods. It can also be more cost-effective than chemical controls.

Physical and cultural practices were developed long before chemical controls became available, and they can be extremely useful for managing pests in the field or garden. They may involve changing the environment to make it less suitable for pests, or they may focus on reducing their numbers by concentrating them in small areas where they cannot damage crops. For example, corn borers are more likely to attack the tallest corn plants in a field; planting strips of shorter plants or seeding with a different variety near a row of taller ones can concentrate them and provide effective control.

Eradication is rarely a goal of pest management, and it is often impossible to achieve in outdoor environments where natural forces influence population dynamics. However, it can be a valuable strategy in indoor situations where pests must be controlled for human health and safety reasons, or when an unwanted organism is present on the premises of food processing or retail facilities. Mediterranean fruit fly and gypsy moth eradication programs are examples of this type of effort.

The key to successful pest management is monitoring. Regularly checking a field, garden or landscape to identify which pests are present, how many there are and what damage they have done helps you determine whether the problem is serious enough to warrant action. Accurate identification of the pest is also necessary to select the best control method and time of application.

Chemical Control

Chemical control refers to the use of chemicals such as herbicides (which target weeds), insecticides (which kill insects), and fungicides (which kill fungus). This method may be used when other strategies have failed to reduce pest populations below damaging levels.

The effectiveness of this strategy depends on the knowledge of how to use the chemicals correctly. It is also important to consider how the chemicals will impact other organisms and the environment. Chemicals should only be used when monitoring indicates they are needed and they should be applied according to established guidelines. These guidelines will take into account the type of pest and the crop, and ensure that they are targeted effectively.

When a pesticide is used, it must be carefully sprayed or spread so that it only affects the target organism and not non-target organisms or the environment. It is also important to note that any chemical used should be labeled, and that it must only be used by a licensed pest controller. This is a legal requirement in the UK, and it is also a good idea to get your pest controller to have a level 2 Award in Pest Management.

A number of chemical-based products are available to help with integrated pest management, including biopesticides, microbial alternatives and plant growth regulators. The microbial alternatives include pathogens which kill or debilitate their host, such as bacteria that attack caterpillars by producing toxin in their midgut, like Bacillus thuringiensis (Bt). These products can be effective at managing over 400 insect species without harming humans and other livestock.

Other microbial products are bacteriophages, which destroy the microorganisms that cause disease by releasing viral proteins into the cells of the offending microorganism. Biopesticides are also produced from the extracts of plants or their spores, and these can be used to kill weeds, or control diseases on fruit and vegetable crops.

Other integrated pest management techniques include the heating or steaming of soils to kill pathogens and weed seeds. These methods are called mechanical integrated pest management, and they can be extremely effective. They are also much safer for the environment and human health than conventional chemical spraying.
