Chemicals commonly used in pest control include insecticides for combating insects and rodenticides for controlling rodents.


Insecticides come in various forms, such as sprays, dust, granules, and liquids, and are widely used to manage pests that cause damage to crops, gardens, and other areas. Active ingredients in insecticides, including pyrethrins, carbamates, organophosphates, neonicotinoids, and synthetic pyrethroids, effectively eliminate harmful bugs. 

Insecticides can be applied directly to plants or sprayed into the air to target flying insects like mosquitoes or flies. Natural fly repellents are also an option.


Pest control companies use rodenticides containing anticoagulants to control mice and rats. These chemicals prevent blood clotting, leading to death from internal bleeding. Some rodenticides use poisons that target the rodents’ nervous system, causing paralysis and death. It’s crucial to follow label instructions to avoid mishandling pets or children.

Pest control companies have a variety of chemical options available to them, each with its own set of advantages and disadvantages. Understanding the types of chemicals used in pest control can help you make an informed decision about which one is best for your situation. 

Next, we’ll explore the potential benefits of using chemicals to eradicate pests.

Benefits of Using Chemicals for Pest Control

With all the ingredients and precautions listed above for pest control, what are the benefits of using chemicals to eradicate pests?

It’s cost-effective. 

Chemicals for pest control can be employed in smaller amounts than other treatments, like fumigation, yet still, provide long-term protection from pests. Additionally, the application of these chemicals usually takes less time than other treatments, so you don’t have to wait days or weeks before seeing results. 

It provides long-term and sustained protection.

There’s no need for repeated chemical applications, depending on the severity of the pest problem. Many insecticides contain active ingredients that continue working even after they’ve been applied, which means you won’t have to worry about re-applying them every few months like some other treatments require. 

It’s just as effective as expensive options.

The quick response of chemical applications means that the infestation can be dealt with quickly and effectively without having to resort to more expensive solutions. Because one application is more than enough for most cases, this means that it’s cheaper to keep your home free from pests.

Just because chemicals for pest control can provide a cost-effective, quick result with long-lasting protection, it is still essential to be mindful of the security concerns when utilizing these substances and follow directions on the label.

To ensure safety when using chemicals that are often toxic for humans and the environment as a means of pest control, follow proper storage and disposal procedures. Wear protective gear and clothing, and carefully read and follow label instructions for application techniques. Check with local authorities for correct disposal methods, such as burying containers 18 inches deep or taking them to a hazardous waste facility.

Protective Gear and Clothing Requirements

When using pesticides, it is crucial to strictly follow label instructions to avoid health risks and adverse effects on people’s health, plants, and wildlife. Mixing different chemicals should be done with caution as some combinations may create toxic fumes. It is also important not to spray near bodies of water unless otherwise indicated on the label. Safety precautions such as wearing protective gear and clothing should always be taken to prevent potential harm. Lastly, it is important to acquire pesticides from reputable sources to ensure their quality.

Shopping online also allows for easy comparison of prices and reviews from other customers, making it easier to make an informed purchasing decision.

What chemicals do exterminators use for bed bugs?

Exterminators utilize a variety of chemicals to tackle bed bug infestations. Common choices include pyrethroids and pyrethrins, which are insecticides designed to target the nervous systems of bed bugs. Neonicotinoids, another type of insecticide, affect the bugs’ nervous systems in a different way. Some exterminators might also use insect growth regulators, which interfere with bed bug growth and reproduction. Alongside chemicals, exterminators often employ integrated techniques like heat treatment and preventive measures to ensure comprehensive eradication.

What do exterminators use for roaches?

Exterminators combat roaches using a range of methods. They often employ gel bait stations and enclosed bait stations containing slow-acting poisons that roaches carry back to their nests. They might also use insect growth regulators to disrupt roach reproduction, sprays with residual pesticides, and dust like boric acid or diatomaceous earth to dehydrate and kill the pests.

Exterminators often utilize an integrated approach, combining chemicals with preventive measures like sealing crevices and improving sanitation.

What chemicals does Terminix use?

Terminix uses a range of chemicals, including pyrethroids like cypermethrin and bifenthrin, organophosphates such as malathion and chlorpyrifos, neonicotinoids like imidacloprid and dinotefuran, and botanical insecticides like azadirachtin.
