Thermacell Mosquito Repellent product works well in outdoor areas where there is minimal air movement, such as decks, yards, and campsites. For best coverage in still air, place the unit close to the ground. This allows repellent to spread over a maximum area. Thermacell products are not intended for indoor use.
Store your Thermacell in a cool, dry place away from heat sources. You can put it in a plastic bag to keep dust and dirt out of it. Always be sure to make sure your Thermacell is working properly if it has been stored for a long period of time.
The fuel supply may be empty. If a replacement fuel cartridge is needed, please turn the unit off and replace the fuel cartridge as shown in the product's instructions.
If replacing the fuel cartridge is not required, please turn the on/off switch to the on position and let the gas flow for 2 minutes before hitting the start button. This will purge the appliance and often corrects the problem.
If the product still does not function correctly after trying the above steps, please contact customer service so we can work with you on a repair, replacement, or refund (receipt required for refund).
Unfortunately, most fuel-powered Thermacell Mosquito Repellers will not work well at higher elevations. At altitudes above 4,500 feet (above sea level), most units become difficult to start and run due to lower air density. Thermacell Radius has no elevation limitations, and the Thermacell Backpacker also operates at higher elevations (up to 7,000 feet).
If you are affected by this altitude product limitation and have no use for your Thermacell at lower elevations, you may return the product for a full refund. Emailcustomerservice@thermacell.net or call toll free 1-866-753-3837 for instructions.
In breezy weather, place the unit upwind of your location so that the repellent is carried by the wind into the area you want to protect. Thermacell may be less effective on very windy days, although mosquitoes aren't typically out when it is very windy.
Yes, you can use Thermacell Repellent Mats for a period of time less than four hours and they will still be just as effective. If there is going to be a significant amount of time between usages (several days +), we typically suggest that you keep the mats in their foil packaging or in a sealed plastic bag between uses.
You cannot bring Thermacell Fuel Cartridges on a passenger aircraft. We typically suggest that you bring your Thermacell Repeller and the mats with you, but purchase the Fuel Cartridges at your destination. You can also ship the product to your destination in advance of your arrival. Thermacell products are sold in over 30 countries throughout North America, Europe, Africa, and Australia; and are available throughout the United States and Canada.
Storage: Store unused mats in a
cool, dry place inaccessible to children and pets. Store mosquito repeller and
fuel cartridges in a cool, dry place away from sources of
Disposal: If cartridge is empty or
for used mats: Do not reuse empty packaging, wrappers or cartridges. Do not
puncture or incinerate empty cartridges. Place in trash or offer for recycling
if available. If cartridge is partly filled or for unused mats: Call
your local solid waste agency for disposal instructions. Never place unused
mats down any indoor or outdoor drain.
First, confirm a refill is inserted properly.Second, make sure the top and bottom of the device are fully nested.Third, check to make
sure Radius is charged.Fourth, check to
make sure Radius is in Unlock or Auto-Off mode as it will not turn on while in
Lock mode. Lastly, make sure you press and hold the power button.
Refills are available in two sizes, 12-hour and 40-hour.
Refills can be used all at once or over multiple occasions. Note that
despite some liquid remaining in the refill after the 12 and 40-hour periods
have passed, the device will no longer provide reliable protection after this
Radius has been built to be durable and resistant to the
elements, but as with most electronic devices, we don’t recommend that you
leave it outside when raining or during other extreme weather conditions.
We recommend using Radius in a stationary location.Moving the device reduces the ability for the
zone to build to its effective state.If
you need to move Radius, allow 10 minutes to re-establish a zone of protection.
Storage: Store in a cool, dry place. Keep
container tightly closed. Should a battery
become ruptured, do not allow contact with water. Keep refills out of direct
sunlight. Do not disassemble appliance.
Disposal: Do not reuse or refill the cartridge. If empty, dispose of unused portion according to label directions: Place
in trash. If partly filled: Call your local solid waste agency for
disposal instruction. Never place unused product down any indoor or outdoor
There are no reported cases where cats have been harmed. The EPA
has no published reports nor records of any incidents associated with the
use of permethrin-treated tick tubes. Furthermore, a toxicity study shows that
a small cat of 3 or 4 pounds would have to eat more than 100 mice per day to
show any adverse effects. Most cats don’t eat more than 6 mice a week,
indicating the risk of exposure is acceptable.
Thermacell Tick Control uses a permethrin treated material targeted
specifically at ticks, rather than a spray or granule that is broadly
distributed. Because the permethrin is bound to fibers, beneficial bugs
are rarely exposed to Thermacell.
When used as directed, Thermacell Tick
Control Tubes do not have any outdoor environmental use restrictions. Unused
product should not be placed in indoor or outdoor drains. Unused product may be
discarded in the trash or offered for recycling.
To make an effective barrier, it's best to put down two rows of tubes in
a grid pattern. Place the tubes every 10 yards along the border of your yard and
the woods. Then put down a 2nd row of tubes 10 yards behind the first row in
the woods spaced 10 yards apart. Start this 2nd row 5 yards to the right of the
first row so that the tubes in the 2nd row fall in between the tubes in the
first row, which makes a grid pattern.
Tick Control Tubes will start to kill
ticks in your yard a few weeks after you apply them. Each mouse can pick
up over 10 ticks a day and hundreds in a season, so you will see a decrease in
your yard as mice take up the permethrin treated cotton and use
it to line their nests. Putting Tick Control Tubes out in the spring
kills nyphal ticks that hatch in April and feed from May until July.
These ticks are the ones that most often spread diseases to humans.
Reapply tick tubes in the late summer to kill baby larval ticks that hatch in
July and feed in August and September. These larval ticks become next
year's dangerous nymphal ticks. By killing both nymphal and larval
ticks in year 1, you will signifcantly reduce the tick population in your
yard and see a marked decrease in ticks the next summer. Reapply tick
tubes each season for best results.
Tick Control Tubes work best on black-legged ticks, also known as deer
ticks, which carry bacteria that cause Lyme disease, Powassan virus and other
dangerous diseases. Tick Control Tubes kill this species of
tick because young deer ticks feed on mice. Tick Control
Tubes do not work as well against other tick species that feed on other animals
such as dog ticks which feed primarily on dogs.
No. The active ingredient in tick tubes is known to be low toxicity to birds. Additionally, the EPA states that the risk to birds is below the agency’s level of concern*. Mice carry only tiny amounts of the active ingredient on their fur after exposure to tick tubes - enough to kill ticks, but not enough to affect birds. *EPA fact sheet for permethrin
Yes. The active ingredient in tick tubes is known to be low toxicity to birds. In fact, it can be applied to birds in a powder form to prevent ticks. While animals might carry trace amounts on their fur, it doesn't harm them as shown in the extensive mouse studies conducted where mice nesting in the treated material produced normal offspring for multiple generations.
