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

"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)

Bought it to control biting gnats as much as mosquitoes. Does a very good job of attracting them and fair job of trapping them. I added 2 sticky traps to sides and the results were amazing. Front yard still has swarms of gnats but back yard around Patriot magnet is significantly better. Have 2 acres total. Just need to get my neighbors on board to help.

This Really Works!

I have had this for two. This is amazing after trying everything except for a mosquito suite. I live in a shaded forested area. I start running this early spring. After a week or two there are No Mosquitoes at all. I have some friends that have been the major targets in the past. When they have came back they can not believe there are no Mosquitoes. Highly Recommended. My friends go out and buy one.

Not great without R-octenol

Jul 4, 2026
These worked great until the got rid of R-octenol. Dont waste your money now, catch rate in coastal NC is 1/3 what it was before they discontinued r-octenol. Just by a fogger, this is not a cost affective option now. Almost impossible to get parts, they want you to send it in and that is the cost of a new unit.
Thank you for taking the time to share your feedback. We're sorry to hear that you've been disappointed with your recent experience.
We understand that many longtime customers preferred R-Octenol. While it is no longer manufactured, we do offer ATRAKTA® Attractant Pods and Octenol Attractant as alternative attractants for our mosquito traps. Performance can vary depending on mosquito species, local environmental conditions, and trap placement, so trying a different attractant may help improve results in your area.
We also appreciate your comments regarding replacement parts and service. Feedback like yours is valuable and will be shared with our product team as we continue to evaluate our products and support options.
Thank you again for sharing your experience.

I have struggled to get this thing to work. Only 1 time did the light stay solid green and next day fast flashing. I have called the number provided and spoke to someone in broken English about how to make it work. That didn’t end well and gave up. I have watched YouTube videos and have tried my best. But something is wrong with this unit. I want to believe in it, but can’t get it to work. Shouldn’t be this difficult

I just purchased my fourth ...

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.
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.
After about 2-3 weeks of use, I am at this point calilng it a waste of funds and propane. Caught so few mosquitos. Very disappointed to this point. Moved it, replaced cartridge, and will see what happens. So far, not impressed.
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

How much propane does the device use? How long does a tank typically last?
Question by: Andrew on Feb 24, 2025, 4:30 AM
