Identifying pests helps tailor control methods. For example, flies can be controlled by keeping garbage cans tightly closed and fixing leaky plumbing. Nematodes (microscopic worms) can be applied to the soil to kill grubs, fleas and other insects.
Prevention, suppression and eradication are the goals of Pest Control Simi Valley CA. Ideally, the goal is to reduce pest numbers to an acceptable level while causing minimum harm to other organisms.
A successful pest control strategy must be a preventative one, as opposed to reactive. This includes an understanding of the biology of the pests, routine property inspections, and use of physical, biological, and chemical techniques to minimize their populations.
The most effective methods for preventing pests include reducing their food, water, and shelter sources; closing off entry points; and disrupting their breeding sites. For example, storing food in airtight containers and keeping trash cans tightly closed helps reduce ant infestations. Likewise, removing overwintering places like wood piles and debris from around buildings and homes can prevent rodents from entering. Caulking and sealing cracks and crevices can also help prevent pests from entering a building or home. Similarly, placing granules or steel wool in the holes of crawl spaces or basement walls can prevent pests from gaining entry to these areas.
Other prevention methods include regularly sweeping and vacuuming floors to remove dirt, dust, and crumbs that can attract pests. It is also important to keep storage areas clean and regularly remove clutter, such as stacks of newspapers or cardboard boxes, that could provide hiding places for pests. It is also important to recycle as much as possible and know your local collection day to make sure trash and recyclables are taken out on a regular basis.
Once pests have gained entry to a structure, they can cause significant damage, contaminate food, and pose health hazards. For instance, mice and rats are known carriers of diseases such as salmonellosis, while cockroaches can trigger asthma attacks and cause illness in humans and animals through ingesting their dry droppings. Moreover, mosquitoes can cause numerous health problems such as West Nile virus, malaria, and Zika disease.
Moreover, pesticides are generally designed to only affect the targeted species, so other insects or animals that come into contact with them may be affected as well. This is why it is important to use pesticides sparingly, according to the instructions on the label, and to observe all safety precautions. Additionally, non-chemical controls should be used whenever possible to avoid the need for pesticides.
Suppression
Suppression refers to the methods and practices used to reduce pest populations to levels below those that cause unacceptable damage or loss. It involves a broad range of techniques, including biological control through beneficial insects, cultural controls and the use of natural pesticides. A successful pest suppression program seeks to create a sustainable balance between beneficial organisms and pests in agricultural ecosystems.
For example, introducing parasitic wasps or nematodes that target the predatory mites of orchard fruit trees can prevent the development of mite pests. Similarly, encouraging predatory birds or rodents to control populations of insect pests can be effective. Biological control methods are often cheaper and less damaging to the environment than conventional chemical pesticides.
In addition to conserving and releasing natural enemies of pests, some farmers also try to limit the growth of problem populations through crop rotation and other physical barriers to pests. They may use netting or screening to prevent the entry of pests into greenhouses or other enclosed structures. In some cases, physical barriers are combined with biological control or chemical pesticides.
Eradication is rarely the goal in outdoor pest situations, and eradication is almost impossible to achieve in closed environments like indoor food processing or storage facilities or health care buildings. Nevertheless, eradication is possible and a worthy goal in some situations where the consequences of pests are particularly severe or unacceptable to human health or aesthetics.
An essential step in controlling a pest population is to understand the life cycle and basic biology of the pest. This can help a pest manager develop a schedule for assessing pest numbers and taking action. For instance, a pest management specialist can develop a “threshold” level, or more precisely an action threshold level, below which pest damage is tolerable and above which specific intervention is required.
Other important aspects of the pest control process are understanding how to evaluate and apply pesticides properly, choosing and using appropriate tactics, and observing local, State, and Federal regulations for applying pesticides. This approach is called integrated pest management, or IPM.
Eradication
Pest infestations aren’t just irritating—they can also pose serious health risks. For instance, rodents and flies can carry and transmit pathogens like Hantavirus and Shigella bacteria through their droppings. And roaches, ants and flies can contaminate food. Thankfully, there are several methods of pest control that work. These time-tested techniques range from preventing pests from getting into buildings in the first place to using insecticides to kill them once they’re inside.
Biological pest control introduces natural predators and parasites to areas with problematic pest populations in order to reduce their numbers without harming other organisms. For example, introducing ladybugs to a garden can help reduce aphid populations, while releasing parasitic wasps can help control caterpillars. Genetically modified plants that contain a toxin effective against a specific pest are also used in some forms of biological control.
Chemical pest control uses various chemicals to kill or repel pests, including herbicides, insecticides and fungicides. These chemical can interfere with the nervous systems, metabolic processes or reproductive systems of pests, causing them to die or stop reproducing. They’re most often used in agriculture to protect crops from insects, weeds and diseases, but are also commonly used around homes and businesses to control ants, roaches and other household pests.
Physical pest control uses traps and other devices to capture or kill problem organisms. Depending on the type of pest, this may include mice traps, electric ants and fly catchers. This method can be time-consuming and ineffective for large pest infestations, but it’s often the best option for quickly dealing with smaller rodents and flies.
Preventing pests in the first place is usually the cheapest and easiest way to deal with them. Sealing cracks and openings, regularly cleaning floors, counters and storage areas, and promptly disposing of garbage can significantly reduce the likelihood of pest infestations. Keeping outdoor areas clean and removing waste materials can also be helpful, as can installing screens on air intake and exhaust vents for heating ventilation and air conditioning (HVAC) systems. In addition, introducing beneficial insects like lacewings and ladybugs to gardens can help to naturally control pests. Likewise, injecting soil with the parasitic nematode Steinernema carpocapsae—which specifically targets and kills cockroaches—can also be very effective.
Monitoring
Generally speaking, monitoring is one of the most important components of a pest control program. It involves checking for and identifying pests, their injury symptoms and crop damage on a regular basis throughout the growing season. It also means looking for the pests themselves in places they like to hide, such as under leaves, inside fruits, or on the soil surface. It is also important to monitor for the presence of beneficial organisms, which can help control pest populations and reduce or eliminate the need for chemical treatments.
The goal of monitoring is to determine whether the pests are at or close to a threshold level, meaning that they are at a number that will cause unacceptable injury to the crop. This information is vital in deciding when and how to begin control tactics.
Monitoring may be done by inspecting the area visually, or using traps. Traps for insect, insect-like, nematode and weed pests often include sticky traps with pheromone lures, or a combination of bait and attractants, as well as sweep nets (used in agriculture, horticulture and forestry) and malaise traps (used in forestry). Some people also use hummingbird feeders to monitor bird populations. Other types of monitoring may include checking environmental conditions such as temperature and moisture levels, to provide clues as to when the pest populations will reach threshold levels.
Regardless of the method used, accurate records are vital for any type of monitoring. Professional pest managers usually utilize prepared log sheets to record the date, time, specific location and pest identification. These records are then used to evaluate the success of any pest management practices implemented in the field.
Monitoring may also involve asking people who work in or visit the site to note any pests they see. This is often the case in offices, schools and homes. In food businesses such as factories, greenhouses or golf courses, asking custodians or staff to note when they see a problem can be a great way to get useful information about the pest situation. It can also be helpful to have people in the food business note the time of day that they see problems, as this can give clues about when the pests are most active.
