PROPANE FIRED MOSQUITO ATTRACTING MACHINES:
In a word....BEWARE
The optimistic sales literature for the propane fired units sounds very appealing. I have two units, something magne? libert? models. The real name should be money magnet "we liberate you from your money"!
They work on the premise that the emissions from the precisely calibrated propane fired catalyst mimmick the breath exhaled by warm bodied hosts, CO2 and H20 at a specific temperature. It sounds like good science and it is. But science has not accounted for the affect of wind currents. Once emitted, the vapor trail is subject to any breeze that may occur and is thus quickly dissapated and rendered much less useful as an attractant. Heck, the user is supposed to also buy and install a chemical attractant. That attractant is made by another company and the EPA stopped the distribution and fined the company because it wasn't registered. A fine was paid and that has since been resolved. My units are registered and I was never notified of any health issues concerning the handling of the attractant or of any EPA settlement, but that's another story entirely.
My two units are sequentially serialized and one burns twice the propane that the other does, just a little problem with calibration?
Some people must like the units, the company is still in business. I'm not happy with my two units, during the one entire season used, I might have caused the dessication of fifty blood seeking pests.
That's like setting fire to a $20 bill every time you smack a mossy.
Consumer reports tested all sorts of propane units, you should research that and others while considering any purchase.
Here is the bottom line: you will still have flies and mosquito's and still get bites so be realistic with your expectations.
SAVE YOUR MONEY, you can buy a CRAP LOAD of repellent for $1000.-
Just MHO, your results may vary,
