What is Thermal Pest Control and is it the Best Option for you?


For centuries, mankind has been fighting pests using strong chemicals and insecticides. For the most part, chemicals do the job well as they provide a quick means of killing pests and prevent them from resurging. The downside, of course, is pretty obvious – these strong chemicals are harsh and can be dangerous to humans and the environment. They require proper handling by experienced and fully equipped pest experts. This is why organic insecticides were introduced, to provide a safe and eco-friendly alternative. The challenge with organic pesticides is that they are not as effective and as efficient as their chemical-based counterparts. This is where pest control heat treatment comes in.

What is Pest Control Heat Treatment?

Thermal pest control treatment is quite a groundbreaking technology. The idea is quite simple – to use temperature (increasing or lowering the temperature) to eliminate pests. This means getting rid of nasty pests such as bed bugs, cockroaches, termites, flies, ants, and wasps can be done without the use of harmful chemicals.  Homeowners can protect their property, family, and pets without worrying about the harmful effects of harsh chemicals. It is also now widely used in office spaces, hospitals, medical labs, nursing facilities, and more. But how does pest control heat treatment work? Is it the best option for you? 

How Pest Control Heat Treatment Works

Like most living things, pests prefer a certain range of temperature. Certain insects also thrive on specific temperatures. Like humans, pests can get dehydrated on hot days too. But since they’re so much smaller, dehydration due to high temperature can be far more lethal for them.  Every creature has what is called a “thermal death point”, which means they die when exposed to a certain temperature after a certain period of time. High temperature can destroy vital proteins and lethally scorches the tiny tissues of insects within minutes. Bed bugs, for example, die when heated to around 120 °F for 20 minutes. Their eggs, on the other hand, are a little more resilient, as they can survive the same temperature for up to 90 minutes.  Other insects have different temperature requirements. Carpet beetles can dry up at 120 °F, fleas at 95° F, and mites at 130 °F. 

The heating process

For thermal pest control treatment to work, pest control specialists need to heat either a confined space or the whole structure to around 120 to 140 °F. This temperature is sustained throughout the structure for around 5 hours or more. They also use tarpaulins to trap the heat and either increase or decrease the temperature in certain areas. Thermal blankets are used to wrap and protect certain areas, objects, and equipment in the property from heat (electronics, vinyl windows, pianos).  Certain items that melt from heat (crayons, wax), house items that spoil in the heat (fresh food, houseplants), and items under pressure (aerosol cans, soda cans, etc.) must be removed. To heat the structure, pest control experts use either electric or propane. The former works by connecting to the power source and introducing hot air into the space. The hot air is recycled and reheated until the room reaches the right temperature.  A propane heater introduces heat to the structure/buildings through a duct. The heating equipment is kept outside the building and pumps in air. Thermal probes are used to determine whether the air being pumped in has reached the desired temperature. The temperature is constantly monitored throughout the process to ensure it is maintained. Once the heating process is completed, heaters, fans, probes, tarps, and ducting are removed, followed by a final inspection. By this time, most major pests, including their eggs, are eliminated. 

So why should you choose thermal pest control over conventional techniques?

Safer for both homes and business establishments

If you do not like the idea of introducing harmful chemicals or pesticides to your property, then pest control heat treatment is the best solution for your pest problems. Chemical treatments can leave harmful and toxic remnants. These can cause eye, nose, and throat irritations, and even serious health problems like damage to the kidneys, central nervous system, and increased risk of cancer.  Symptoms of irritation from chemicals include dizziness, nausea, headaches, and muscular weakness. This is why chemical pest control requires experts that can handle the harmful substances safely and effectively.  Heat does not leave any residue. Since no chemicals are used to treat your property, you can safely return to your pest-free home or commercial building with peace of mind.

Efficient and Requires Less Time

For chemical treatment to be effective, pest control providers must be willing and able to get to hard-to-reach areas and spray the insecticides and pesticides into the tightest of spaces and crevices. Thermal pest treatments work by heating the entire structure. Heat radiates into the walls, all the way to the items and belongings you have inside your property. This eliminates missed spots and areas as hot air can seep through the tightest of spaces, eliminating the need to repeat the treatment.  There will also be no need to bag and seal off items and objects in your home to prevent damage. Obviously, there are certain steps you need to take to protect certain items, but it is far less extensive when compared to chemical pest control treatments.  Also, when using chemical treatment, you may be required to vacate your premises for at least three days. This could mean you have to make alternative living arrangements, such as living in a hotel or family member’s home. With thermal pest control, the process can be completed in one full day. Most of the time, you can return on the same evening. Heat also kills all stages of a pest’s life – from adult to eggs. This makes pest control heat treatment far more convenient for homeowners. 


Thermal pest control treatment is by far the more environmentally friendly option. You do not need to worry about the harmful chemicals and pesticide residue left in your home.  Also, chemical treatment requires repeated sessions (second treatment after fourteen days) to kill off the eggs and those that may have survived the first session. This means your home will be exposed to more chemicals. With thermal treatment on the other hand, all it takes is one visit.
