With the Mosquito Magnet® Patriot Plus, you can establish a defense zone for your home or business that drastically cuts back on the breeding population of biting insects. This CO2 mosquito trap targets all the biting insects you hate – mosquitoes, midges, no-see-ums and black flies. By using a mixture of attractants, including moisture, heat, CO2 and special scents, the Mosquito Magnet® lures biting insects to the machine where they’re sucked up inside the trap, ultimately dying from dehydration.

This unique mosquito trap is backed by 15 patents and more than two decades of research and innovation. The technology in Patriot Plus has been proven to effectively break the breeding cycles of mosquitoes. Each trap covers about 1 acre, requires a propane tank, attractant packs and nets, and it’s backed by a 1-year limited warranty.

How it Works

How it Works

Mosquito Magnet® traps work using attractants that draw hungry, female mosquitoes, black flies, no-see-ums and midges to the machine. Once the mosquito flies close to the device, the CounterFlow vacuum sucks the insect into a net inside the trap. The powerful vacuum holds the mosquito in the net, where the insect dehydrates and dies. Each trap provides about 1 acre of control.

Counterflow Technology

Mosquito Magnet® machines use CounterFlow Technology to push out a trail of odorless attractants while also creating a powerful vacuum that traps mosquitoes and other insects.

CounterFlow Technology - follow the steps below:

  1. Set the trap in your yard. It should be 30-40ft away from people and in the shade.
  2. Trap's Patented technology converts propane to CO2. The CO2 released, attracts mosquitoes to the trap.
  3. Secondary attractant mixed with CO2 attracts mosquitoes. It increases the mosquito catch rate by up to 10 times.
  4. Patented technology. Mosquitoes get sucked into the plume and into the net.
  5. Mosquitoes dehydrate and die in the net. Once in the net, mosquitoes will dehydrate and die within 24 hours.
  6. Enjoy a mosquito free backyard!

Target These Unwanted Insects

The Mosquito Magnet® Patriot Plus will help you control these insects in a one-acre area emanating from the trap.

  • Black Flies

Five Stars

"Works great. The net was almost full when the 1st tank of propane ran out. Using the R-Octenol in Northwest Wisconsin, (and it) has worked very well. Can be outside at sunset, and I don't even get bit." (Review from Up North Guy)

I just purchased my fourth ...

Sep 28, 2025
I just purchased my fourth unit. Why? Because it works. I live on a half acre parcel and can sit on both my front and rear porch with virtually no mosquitos (and they generally love me). My neighbors also reap the rewards of my unit and are relatively mosquito free. Now, the downside. Living mosquito free is not cheap.The units seem to last bout four years. When the first one stopped working, I sent it in for repair. By the time I shipped the unit and paid for the repair I had spent over half the cost of the unit - which was still over four yers old. Now I just buy a new one (which by the way did not come with even a single octenol cartridge). I generally go through about six tanks of propane a year ($20 each) and a new octenol cartridge each time ($12 each) - $192/year. If you assume the unit has a four year life span (at approx $400) the annual cost is another $100/year. So based on my experience, the cost of being “mosquito free” is around $300/year or $40-$45/month. A luxury if you can afford it, but go in with your eyes wide open. For me, being able to fully enjoy being outside all night without being eaten alive by mosquitos is worth the cost.

Aug 20, 2025
After 3 years I had to replace the power supply. Worked briefly and then would not start. Used YouTube videos to take apart and troubleshoot. The nozzle into the combustion chamber is black and clogged. Tried cleaning it. Opened up the combustion chamber. A bunch of residue clogged the exhaust end of it. The closest service tech is 2 provinces away. He was very helpful. He is sending a new nozzle and a nylon bolt. Spent hours trying to get it to work. So far. A huge waste of my time. Give the new nozzle resolves the issue. Never got rid of mosquitoes in the garden anyway

We’ve been using this for about 6 weeks so far in the main part of my backyard which has dense vegetation and trees. I used to get upwards of 15 bites in the evenings - now, maybe I get 1-2 very periodically! One full propane tank lasted over a month. Hope this Mosquito Magnet lasts for many seasons!

Not impressed at all. After using the Liberty Plus for 15+ years, the Patriot Plus is not worth the money. Worked when we bought it. Last summer. Now, after doing numerous maintenance stuff, Connor get it to run. Waste of money. Waste of time. I do not recommend it.

Does not really change the mosquito infestation in our garden or yard. Does trap some mosquitoes but they are still prolific. After 3 years the power supply died. Waiting to see how they address this problem.

Do not recommend.

Jun 10, 2025
Do not recommend. The Patriot is not even one year old. It caught a handful of mosquitoes last summer even after moving the machine multiple times. This year when set it up outside I got an immediate error code. The machine was stored covered in the basement as recommended. The machine kept turning off after a short time once I did clear the error. Once it really seemed like it was good to go, with mosquitoes swarming the machines attractant - maybe 5 bugs were in the net. Customer service has been completely not helpful. They referred me to someone in Wisconsin who was not helpful either. Don’t waste your money!

What happened to cleaning out the lines with the CO2 cartridges? Or the plug thing you could attach between the machine and the propane tank to clear those lines?
Question by: Malinda on Jun 7, 2025, 11:29 PM
Even though Quick Clear Cartridges are no longer recommended, the trap will work perfectly with or without the black valve cover. For general maintenance, wipe down the outside of the trap with a clean, water-damp cloth as needed. Thank you for your question! If you have any further doubts, please feel free to call us. It would be our pleasure to assist yo
