Thermacell Mosquito Repellent Device

If you attract mosquitoes like a magnet and you’re looking for a way to keep them at distance the Thermacell Mosquito Repellent Device could be what you’re looking for.

In this review, you will discover the advantages of using this product.


What is the Thermacell Mosquito Repellent Device?

This is a small mosquito repelling device measuring just 10 x 6 x 2 inches and weighing 2 pounds. This means it can be carried around and used anywhere you need it for example when you’re fishing hunting, camping, in your garden or even when you’re walking. You can be totally mobile and not have to spray yourself with unpleasant repellents.

The Thermacell devices create a 15 ft x 15 ft (depending on the wind) mosquito free zone.


How does it work?

The Thermacell Mosquito Repellent Device works the same way as the other Thermacell Products the Lanterns or the Torches.

The device is powered by a small butane cartridge. The cartridge heats up a mat that’s saturated with the repellent. With the effect of the heat, the repellent is dispersed into the air, creating a zone of protection.

You can see how it works in the video below.

The Repellent

Thermacell appliances use a repellent called allethrin. Allethrin is a synthetic version or pyrethrum. Pyrethrum is a botanical insecticide found naturally chrysanthemum flowers. Allethrin was introduced in 1949.


Is Allethrin Safe For Adults And Children?

Thermacell have sold hundreds of thousands of repellent devices and millions of refill mats. Apparently, there haven’t been any health problems reported to the company.

There have been some studies conducted on the effects of Allethrin on humans. Even in a worst case scenario, where a Thermacell device was operating indoors, in a room with no windows or ventilation and was running for 8 hours. The scientist running the study came to the conclusion that a Thermacell device does not pose an unreasonable risk to adults or children.


Field Tests

There have been several scientific field tests carried out by different bodies, notably the Department of Defense, and on 4 continents.

The results for mosquitoes, sand flies and no-see-ums were quite conclusive. In an area 7.5 feet each side of the device, it was 95-98% effective. There was some protection up to 25 feet from the unit.

In a test against black flies, protection was optimal at 3.75 feet from the device. This test was carried out in windy conditions, in calm weather, the area would probably be greater.
