How Thermacell Works

Thermacell works by using a heat source to activate a replaceable mat containing a repellent substance. When the mat heats up, the substance disperses into the air and forms a protective zone around the device. The protection builds up gradually and reaches full effect after about five minutes. Within this zone, the risk of mosquitoes approaching and biting is reduced. The effect is limited to the area where the device is placed and is influenced by wind and air circulation. 

Thermacell does not affect mosquito reproduction and has no effect on mosquitoes outside the protection zone.

Practical Use

Thermacell is used outdoors where you stay for a limited time. The product is placed near the seating area or workspace and started before you sit down.

For best function, the device should be used in relatively sheltered environments. For larger areas, multiple units can be used to cover the area. The protection is active as long as the device is running and the consumable parts are functional.

Thermacell does not replace long-term mosquito control in the yard but acts as a complement when you want immediate protection where you sit.

Common Questions about Thermacell

Here you will find factual answers on how Thermacell is used in practice, what affects its effectiveness, and how to choose the right solution for patios, camping, and gardens.

How does Thermacell work?

Thermacell is a repellent mosquito protection that creates a protective zone by heating a mosquito repellent mat. The substance disperses in the air around the unit and reduces the risk of mosquitoes coming close where you sit.

How quickly do I get protection after starting Thermacell?

Expect a short start-up time before protection is established. A practical rule of thumb is to start Thermacell about 5 minutes before you sit down, allowing the protection zone to be established.

Where does Thermacell work best?

Thermacell works best outdoors in relatively sheltered places, such as on a terrace, patio, barbecue area, or camping site. Strong wind can reduce the effect since the protection disperses faster.

Can I use Thermacell indoors or in a tent?

Thermacell is intended for outdoor use. In confined spaces, ventilation is crucial and use might be inappropriate. Always follow the product instructions and safety information regarding where and how it may be used.

How do I place Thermacell for best effect near a table or seating area?

Place Thermacell close to where you sit but ensure it stands stable and will not tip over. On a patio, it is often good to place it at the edge of the seating group, somewhat sheltered from the wind. If you move, take the device with you to maintain protection.

What affects the effect the most?

The most common factors are wind, how close you sit to the device, and whether Thermacell has time to build the protection before you are exposed. Many competing attractants (e.g., several people, pets, or strong odors) can also affect mosquito behavior in the area.

How long does the consumable last, and what do I need to replace?

Thermacell uses consumable parts that need regular replacement (e.g., repellent mats and fuel/power source depending on the model). For best function, it is important to replace according to recommended intervals and always use compatible refills for your device.

Can Thermacell be used together with an exterminating mosquito trap?

Yes, it is often a good combination. An exterminating mosquito trap can reduce the mosquito population over time, while Thermacell provides more direct protection where you sit. Together they can offer both long-term reduction and quicker comfort on the patio.

Is Thermacell safe to use around children and pets?

When used normally and handled correctly, Thermacell is designed for outdoor everyday environments. Place the device so that children and pets cannot reach or tip it over, and always follow instructions about safety, handling, and storage of refills.

What should I do if I still get bitten despite using Thermacell?

Start by checking the most common causes:

  • Start time: start the unit about 5 minutes before you sit down.
  • Placement: move it closer to the seating and more sheltered.
  • Consumption: ensure refills are active and correctly installed.
  • Wind: in windy weather, you might need to change position or create more shelter.

If there are many mosquitoes, an exterminating mosquito trap as a complement can give better effect over time.
