Pest Control

Pest Identification

Pest control involves stopping pests from damaging people, property, and the environment. The goals of pest control are prevention, suppression, and eradication.

Preventing pests is the best way to protect your property and the environment. Many pests can be controlled without the use of chemical pesticides. Preventing pests includes removing food, water, and shelter and using resistant varieties of plants, trees, and animals. Contact Pest Control Woodland Hills CA now!

Pest identification is the first step in developing an integrated pest management strategy. Identifying pests provides information that is fundamental to all other aspects of IPM – understanding what the pest is doing, where it’s coming from and how and when it reproduces.

Correct identification makes control easier and much more effective. Whether it is a weed, insect, animal or microbe, pests can look quite different as they go through their life cycle. As a result, pests are often misidentified and the wrong control tactics may be used. This can be costly in terms of time and money, but more importantly, it can also put people or the environment at unnecessary risk.

It is particularly important to know the species of a pest in order to use appropriate non-chemical methods for their control. Insects in particular have dramatic changes in appearance as they go through their life cycle, and even within the same species there can be a variety of physical forms. For example, a weed seedling can look very different from the mature form. In addition, many insect pests can be difficult to differentiate at the order level and species identification is essential when selecting an approved biological insecticide such as Bacillus thuringiensis which is only active against specific orders of insects.

Museums have an enormous amount of resources to help with pest identification, including online identification guides and a number of key references. Some of these can be found on our Insects and other Pests page. Carefully collecting a specimen in a clear jar or plastic bag can help with identification. In some cases, it will be necessary to contact a pest identification specialist for assistance.

Identifying pests can be the most challenging aspect of a pest management plan. Some pests are a continuous threat, others are sporadic and only present at certain times of the year and in specific locations. It is important to understand the differences between these and other factors in determining an integrated pest management strategy.

Identification can also be important in establishing action thresholds. For instance, some pests have established populations at which a certain action must be taken, such as in food processing facilities where any rodents would require immediate control. In other situations, action must be taken when a pest is present at levels that cause unacceptable damage or injury. Establishing these thresholds can reduce the need for pesticides and help ensure that only the necessary amounts of chemical are used.

Prevention

Pests like rodents and insects pose more than just a nuisance; they can be a serious health risk as well. They can spread diseases like hantavirus, leptospirosis, salmonella, and more, while causing property damage. Pests can also gnaw through electrical wiring, leading to fires and other costly problems. Preventive pest control techniques can help protect your family and employees from these hazards.

Structural preventive strategies are designed to create barriers that stop pests from entering your property or building. They include a variety of tactics, including sealing gaps and cracks, caulking, modifying the landscape to prevent nesting sites, and regular inspections to look for signs of infestations. These measures can often stop pests before they cause major problems, reducing the need for expensive treatments and full exterminations.

Regular pest inspections by a professional can identify the early stages of pest infestations before they become severe or unmanageable. During these inspections, technicians check the common entrance points of pests, inspect the conditions that may attract them, such as food, water, and shelter, and take steps to address any issues found. This can prevent minor problems from escalating into costly pest infestations that require extensive treatment and repair services.

Pest prevention requires a multi-faceted approach, and each tactic should be evaluated for its effectiveness and potential harm to the environment or people. This includes knowledge of a pest’s lifespan and life cycle, which will allow you to intervene at the right time, such as when they are just starting to hatch or before they begin to damage the environment. It also requires an understanding of what kind of impact each intervention will have on the surrounding ecosystem, and adherence to local and State regulations.

The most effective pest management involves integrated pest management (IPM), an ecologically conscious and holistic approach that focuses on preventing pest infestations rather than just controlling them when they occur. IPM uses a variety of techniques, including habitat manipulation, modification of cultural practices, and use of resistant varieties of plants and animals, to prevent pests from becoming a problem. When chemical pesticides are necessary, they are used only in the most appropriate locations and at the lowest possible doses to minimize risks to humans, pets, and the environment.

Treatment

Pests can be a nuisance or a health threat and should always be dealt with promptly. They may contaminate food, damage crops and personal items like clothing, linens and woodwork. They may bite or sting, causing irritation or allergic reactions in people, animals or plants. Some transmit diseases such as rabies, salmonella and hantavirus. Others can damage buildings and structures, like ants, bees, wasps and cluster flies.

Sanitation practices can prevent and suppress some pests by removing their food, water or shelter. For example, pests can be deterred by storing food in sealed containers in retail and hospitality establishments and by removing garbage regularly. In agriculture, avoiding carryover of pests from one field to another can be accomplished by using pest-free seeds and transplants and by cleaning equipment and washing vehicles and equipment before moving between fields.

Some cultural controls are also effective in reducing pest numbers. For example, weeds that compete with crops for nutrients can be controlled by changing cultivation practices or by removing them. Other cultural controls include the use of natural enemies, such as predators, parasites, and disease organisms (pathogens) that reduce pest populations; and pheromones, which are chemical messengers that control insect behavior.

In some situations, especially in enclosed areas such as homes and offices, eradication is a viable goal. However, this is rarely a goal in outdoor pest management. Instead, a more realistic objective is suppression – reducing pest numbers to an acceptable level with as little harm to non-target organisms as possible.

If other management strategies fail, the use of chemicals may be required. This includes herbicides to kill weeds and insecticides to kill pests. It is important to choose the most selective and least harmful chemicals and to follow the label instructions carefully.

An integrated pest management plan begins with a thorough evaluation of each pest situation. This involves understanding the life cycle and damage potential of each pest, its natural enemies, and environmental factors that influence its growth and development. This information can help determine the most appropriate tactics to manage each pest, whether prevention, suppression or eradication is desired.

Monitoring

Inspecting and recording information about pests enables you to determine the extent of a problem, whether current prevention or avoidance tactics are working, and if a particular pest control action should be taken. The interpretation of monitoring data, called assessment, is what distinguishes IPM from other pest management strategies. It answers questions such as: “Is the problem getting out of hand?” and “What should I do about it?”

Some methods of monitoring require an eye for detail, like examining secluded areas where pests may live or seek shelter, to locate harborage sites. A good flashlight is helpful for this, as well as a magnifying glass to help with identification of pest parts and damage. A telescoping mirror is a handy tool for inspecting behind and underneath equipment, where pests often hide.

Trapping can be used for both monitoring and controlling pests, and there are many different types of traps. Some are passive, designed to intercept a pest during its normal activities, while others contain an attractant or pheromone to lure the pest. Species-specific pheromone traps are especially useful for stored product pest (pantry pest) monitoring, as they enable you to capture and identify specific pests rather than general categories of insects.

Other types of traps can be used to control, and sometimes even eliminate, pests, by altering the environment they inhabit. Heat, humidity, radiation, and alterations of water can all affect the environment to a degree that will reduce or eradicate some pest populations.

In a museum, monitoring can be accomplished with a variety of devices, including traps, baits, and acoustic monitors that emit sound when an insect is present. In some cases, a nontoxic prebait can be used with toxic baits to increase the acceptance of the final bait, making the use of poison more cost effective.

Regular, ongoing scouting and monitoring can be highly effective in reducing pest problems in a facility. This practice increases awareness of pest presence, activity, and needs, reduces the amount of unnecessary, routine pesticide applications, and assures that pesticides are used at the proper life-cycle stages for their greatest effectiveness.
