What Does a Pest Control Do?

Pests can contaminate food (such as rats, cockroaches, bees and hornets), introducing bacteria or making it unfit for consumption. They can also damage buildings, plants and crops.

Prevention techniques include keeping the environment clean and blocking points of entry for unwanted organisms. This may include repairing leakscaulking cracks and using knitted copper mesh along pipes and drains. Contact Pest Control Garland TX now!

How Much Does Pest Control Cost in 2024?

Ideally, pest control should focus on prevention of problems. Preventive measures can range from reducing accessible food sources (storing food in sealed containers or throwing out old foods) to keeping grass and shrubs trimmed away from the house to prevent rodent pathways. Preventive measures may also include removing wood piles that can attract beetles and termites and sealing the smallest cracks to prevent insect entry.

Pest identification is an important step in any IPM plan, because it allows technicians to tailor treatment methods for specific pests, which reduces off-target impact and overall chemical use. It is essential to understand what conditions allow pest populations to thrive, so technicians can advise customers on things they can do to limit the pests’ access to water and food. For example, some pests require water to regulate their body temperature. Moisture can build up in humid areas, and some pests, such as mosquitoes, lay their eggs in standing water. Leaky pipes, water fountains and clogged gutters can all attract pests by providing moisture.

In addition, regular inspections can detect and catch pest activity early. This helps to identify the problem before it becomes severe and saves money on costly repairs. Educating clients about pests, their habits and ideal habitats empowers them to take action, and may help minimize the need for more aggressive treatments.

Chemical pesticides are an effective way to eliminate pests, but they can be harmful to the environment and people. They often disrupt the nervous systems of targeted insects and can kill or harm other organisms, such as beneficial insects or non-target plants. Chemical pesticides are available in sprays, dusts, gels and baits.

Physical and mechanical controls include caulking or other sealant to fill in small gaps around doors, windows and vents; replacing damaged screens; and ensuring that all trash is promptly disposed of and stored properly. Managing waste can be critical to controlling pests, especially when cockroaches and rats have access to garbage. Regularly cleaning counters, sinks and floors can remove crumbs that may attract them, and removing pet food, bird feeders, compost bins and other outdoor supplies can limit the opportunity for pests to find shelter.


The goal of suppression is to reduce pest numbers or damage to a level that is acceptable. This is often combined with prevention and may involve physical, biological or chemical methods. Ideally, control methods should cause as little harm to other organisms (including beneficial insects) and the environment as possible.

Keeping pests from entering an area is the best way to avoid a pest control problem. This includes removing food, water and shelter sources and fixing leaky plumbing. Regularly removing garbage and reducing clutter also help prevent pests.

In enclosed environments, pests can be more difficult to control than in outdoor settings. This is especially true in health care, retail and food preparation facilities, where the presence of pests can create a health hazard. Rodents, for example, can spread disease through their droppings, and mosquitoes are a nuisance in many areas.

Chemical pesticides, which come in the form of aerosol sprays, dusts and baits, can be used to control pests by disrupting their nervous systems or killing them. They are usually regulated by the Environmental Protection Agency and are relatively safe for humans if they are used correctly. However, they can still cause environmental harm through runoff and contaminate water supplies.

Another way to control pests is by using natural enemies. This requires careful research into the biology of the pest, as well as potential native enemies and their biology. Suitable natural enemies must then be collected, quarantined and released in a location that is appropriate to their life cycle and the habitat of the pest. This is done with the goal of eliminating or reducing the number of pests through competition, predation or parasitism.

Threshold-based decision-making can also be useful in this area. For example, if you see a few wasps around your garden or home, that probably doesn’t warrant spraying with insecticide, but if you are seeing them in large numbers every day, that might be the time to take action.


Pests can be a significant problem for domestic and commercial premises. Insects, such as ants, cockroaches, bedbugs, fleas and wasps or bees can infest buildings, ruining the environment and creating health problems for people and pets. Rodents, such as mice and rats, can also cause problems and may carry diseases and damage property. Pest control methods are varied and can include fumigation, which involves sealing a building and filling it with gas to destroy the pests. Other common chemical pest control methods include ultra-low volume (ULV) fogging, which sprays small quantities of pesticide in the air to kill insects, and baiting, which uses chemicals to attract and then poison the pests. Biological methods include the use of parasitic nematodes, which are microscopic worms that live in the soil and attack pests, such as fleas, grubs and slugs. Pheromones, which are naturally produced by the female insect to attract males, can also be used to control pests by disrupting their reproductive process.

The best way to deal with pest infestations is by preventative measures, preventing them from getting into the home or business in the first place. It is important to check for cracks and crevices that pests could use to gain entry, such as around window frames and the foundation of a house. Also important is a regular exterior inspection, checking for woodpiles near the house, holes in the siding and roof and unkempt grass and garden areas.

Other preventive measures include a number of DIY treatments. For example, boric acid can be sprinkled over most surfaces to kill pests such as cockroaches and fleas. It is also effective when blown into crevices with a hose. Alternatively, you can try traps and baits, such as pheromone traps for insects or a mousetrap for rodents. If you decide to hire a professional, ask them to provide information about the chemical they will be using and its EPA registration number. Read the label carefully to ensure you understand how to properly apply and store the chemical.

Another prevention measure is to create a deterrent for pests, such as building up a scrap wood pile on the perimeter of a farm to draw pests away from crops and then exterminating them with pesticides. Diversionary elements can also be used, such as a hive or compost heap that is specifically designed to encourage bees and wasps to take up residence in it.


In indoor spaces, such as dwellings; offices; schools; hospitals and health care facilities; food processing plants; and restaurants; pest control is a critical element of good hygiene. Pests can cause direct damage by chewing or scratching surfaces, carrying disease, contaminating food or spreading allergens. They can also transmit germs such as bacteria and viruses. They are a serious hazard to building occupants, especially those with asthma or allergies. In addition, they contaminate and stain fabrics and carpets and create unpleasant or toxic odors. Safe pest control is a responsibility shared by building owners, managers and maintenance workersoccupants and tenantsand the environment.

Pest management begins with accurate identification of the pest. This can be done by someone familiar with the pest and its habits, or by a specialist. Once the pest is identified, the proper control measure can be selected.

Physical control involves blocking pest entry points into a structure or yard. This can include screening windows and doors, removing debris piles, and using traps and baits to capture pests. It also includes preventing pests from finding food, water and shelter by reducing trash and garbage accumulation, avoiding overcrowding in structures and modifying vegetation.

Biological pest control uses natural enemies  predators, parasites and pathogens  to reduce or eliminate pest populations. These enemies can be introduced naturally, or they may be bred in the laboratory and then released at a controlled time to provide long-term control.

Chemical pest control uses synthetic substances to kill or repel a pest. They are typically sprayed, but can also be applied in baits or as a powder. They are usually very effective in controlling a wide range of pests, but can be hazardous to people, pets and the environment if they are not used correctly or are overused.

Pesticides are important tools in pest control, but they should be used only when necessary and always with caution. It is best to try preventive measures first, and use chemicals only when the pests are resistant to other methods. The least-hazardous pesticides are generally those that target only the specific organism that needs to be controlled.
