If you are the owner of a mosquito propane trap machine you will need to refill the tank about every 21 days.  Every brand name mosquito propane trap is different, and the refill time depends on how long you run the trap and how large your propane tank is.  Some people will purchase a second propane tank so that there is no downtime of mosquito catching during the tank filling process.

The benefit of a mosquito propane trap is that you may not need an electrical source to run it.  Many models have a hybrid system combining natural propane power with thermoelectricity and batteries.  Be sure to avoid buying any sort of trap that has an open flame, as this can cause harmful fires in your yard or campsite.

There are accessories available to go with your mosquito propane tank, such as protective weather covers and additional mosquito attractants like Octenol.  Be sure to get a model that is easy to transport in case you want to bring it along on a camping trip, as well as for easy storage in the winter months.
