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

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.

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) Read More Reviews »

CO2 Cartridges By Paul

When the Mosquito Magnet works, it does a very good job. The problem I have is the blinking red light is constant. I've tried everything. A friend owns one and he told me I need to add CO2 regularly for it to work. I did not receive an owners manual and was not aware of this. I ordered CO2 for the Mosquito Magnet from Amazon specific to this machine and received the wrong CO2 twice. The CO2 nozzle is too large to fit into machine. Amazon won't return these CO2 cartridges because they are combustible. Can you assist me with this?

Useless Product By kkruzer

I have one but can't get it to keep running. Sent it out west for repairs and by the time it came back the season was over. Now I try it and it still won't keep running - shuts itself off. Now the warranty is over and we're out $400. Poor product and poor service.

Response From Mosquito Magnet®
Jules : Consumer Relations Representative

We're sorry to hear about your experience with this trap! While the trap comes with a one-year warranty for repairs, we also offer out-of-warranty repair options for the Patriot Plus Traps. Repairs can be done at our facility for a flat fee, or the trap can be taken to one of our many Certified Service Centers around the country. For more information on these options, we recommend giving us a call at (800) 953-5737. We're happy to help!

Made a difference By Sam

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.

IT WORKS! By Gerald

It works! If you ever doubt it, just turn it off and I promise you’ll realize the difference.. I had a MM Liberty model for around 15 years and it did the job, it gave out and immediately replaced it with the Patriot Plus. I know it can seem expensive to maintain and operate the MM, but it’s worth it! There are cheaper traps out there, but the dependability, effectiveness, longevity, and value of the Mosquito Magnet far exceeds them all.

This Really Works! By Flower Lady

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.

Still testing it By hazel

The suction I find is weak and to me it should have more force and the attractant to it doesn't work

Response From Mosquito Magnet®
Lauren : Consumer Relations Representative

Hello Hazel,

Thank you for sharing this feedback. Mosquitoes are poor flyers, which is why only a light suction is needed to pull them up into the trap. The recommended attractant can vary depending on your geographical location. Please feel free to contact us at 1-800-953-5737 so we may learn more about what is occurring and provide assistance.

Q. Is this machine safe around honeybees? We raise honeybees on our 1 acre property.

The CO2 emitted by our Mosquito Magnet® traps and secondary attractants used with the traps have not been shown to be attractive to honeybees. We recommend placing the trap away from active hives, as if a bee were to investigate the trap closely, there is the potential that they could be pulled inside.

Q.Understanding that for the Mosquito Magnet Patriot Plus, a 20 (twenty) pound tank is the required weight for the necessary propane tank to be purchased separately, does the “shape” and/or “size” of the propane tank itself have any specific specs that need to be met?

As long as the propane tank is 20 lbs, the shape or physical size of the tank does not matter, our traps are all inclusive.

Q.Luxe3 carthridge wil not seat in my Patriot Plus ? Why? Greg

To attach the Lurex3 cartridge, remove the attractant carrier cap and click it to the bottom of the tube. It fits on the same way as the cap.
