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.

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.

Works great when it works.

Works great when it works. I am now returning the second of 2 Patriot Plus units purchased this summer. The first failed after 3 weeks. The second, after 7. FWIW, I've used these traps for over 10 years and understand how they operate. Trouble is, when you return a device under warranty, it takes upwards of 6 weeks to get your unit back. You also lose one of your pricey bait packs. And the pests return with a vengeance. Next year, I plan on purchasing a second unit the day the current one fails. Hopefully, the new unit will not fail before I get the old unit back.
Thank you for sharing your experience and for being a longtime Mosquito Magnet customer. We’re glad to hear the Patriot Plus works well when operating, and we understand how important consistent performance is during mosquito season. For the best possible operation, we recommend following the setup and maintenance instructions carefully, including keeping the trap positioned in an open area away from competing light and wind sources, checking the propane supply and fuel connections, and keeping the trap clean and properly maintained throughout the season. Regular inspection of the net and other components can also help support reliable operation. We appreciate your feedback regarding the warranty process and turnaround time, as well as the impact of the bait packs during service. Your experience is valuable to us as we continue working to provide dependable mosquito control.

Just. Doesn’t. Work. It doesn’t do what they promise it will. I have a half an acre, tried three different locations over a three month period and while it trapped some bugs, overall didn’t notice any decline in the amount of mosquitoes. I even used the fancy extra expensive lures, going so far as to use both lures on the last attempt. This was a massive outlay of money and there was ZERO return on investment. You’d be better off with anything else costing hundreds less. It’s your money, I’m just here to tell you it will be a big waste of your time. And money.
We’re sorry to hear the Mosquito Magnet® Patriot Plus Mosquito Trap did not provide the results you expected. Placement and operating conditions can have a significant impact on trap performance. For best results, place the trap approximately 30–40 feet away from people and the areas you want to protect, preferably between the mosquito breeding area and the area you want to protect. Keep the trap away from competing attractants such as outdoor lighting, fans, and other sources of CO₂. It should also have adequate clearance around the unit for proper airflow and be positioned according to the instructions in the manual. Allowing the trap to operate continuously is important, as mosquito populations can take time to decrease. We hope these tips help improve the performance of your trap.

Tried both types of bait

Aug 25, 2026
Tried both types of bait, full propane tank, brand new out of the box. Only caught like 5 mosquitos over a 3 week period in southern state in August. They are swarming around it, but don't seem to find their way into the trumpet/net. It actually can make the problem worse because it attracts all the neighboring mosquitos, and without enough suction or reason to go up the tube, when you go outside they switch to you. Really wanted it to work, but back to the store.
We’re sorry to hear the Mosquito Magnet® Patriot Plus Mosquito Trap did not provide the results you expected. For best performance, make sure the trap is positioned according to the placement guidelines, ideally in a shaded area with the exhaust directed away from the home and the trap positioned between the mosquito breeding area and the area you want to protect. Keep the trap away from competing mosquito attractants, such as standing water, lights, and areas where people gather. Also, allow the trap to run continuously, as it can take time to reduce the local mosquito population. Checking that the propane tank is properly connected and that the trap is operating with a steady flow of air can also help ensure proper performance. We hope these tips help improve the trap’s effectiveness.

Just doesn’t work, not a single mosquito in a month of operation

I purchased this based on all the reviews which seemed to suggest that it was very effective. I’m afraid I can’t agree this thing just doesn’t work, it has not attracted a single mosquito. I have tried various locations 2 types of bait and we are still getting bitten. Absolutely worst purchase I have made, I only bought it because my wife stopped me using spray products…. We will see how she feels about this after a season of being bitten to death. I really want to return this but I imagine it’s going to be a nightmare.
Thank you for sharing your experience. We’re sorry to hear that the mosquito trap has not attracted mosquitoes as expected. We understand how frustrating it is to continue getting bitten after trying different locations and bait.
Since this is a propane-powered mosquito trap that generates CO₂ to mimic human respiration, placement is especially important. For best results, place the trap away from people and areas where you spend time, preferably between the mosquito breeding area and the area you want to protect. Avoid placing it directly beside your patio or seating area, since mosquitoes may be more attracted to people than the trap.
Give the trap sufficient time to establish its attraction pattern, as mosquito populations and activity can vary with weather and environmental conditions.
We’re sorry the product has not met your expectations, and we appreciate you sharing your experience. Your feedback will be passed along to the appropriate team for review.

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 ...

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.
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
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
