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 withint 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 »

Worth it. By Darlene

We just bought our second patriot plus. The catch net is over half full! We live on the edge of hillside/green belt so the mosquitoes are a huge issue. We moved out first patriot plus to the outside corner of property because we keep pushing out the yard. Our close neighbor just purchased two because of our recommendation and a friend is purchasing his first. It’s an amazing system and worth the investment.

Works well By Ted

Works really well. Net is usually half full when I change propane tanks. Lots of mosquitos here on the coast, and this is my third magnet for an acre. Guests are amazed that they do not get bitten outside!

Devoted Fans By LL

We having been using your product for 15 years after moving to North Texas. We had been unable to sit outside due to the mosquitos. Once we installed the Mosquito Magnet the Pest population disappeared and we were able to enjoy our backyard and outdoor Grille. We are devoted lifetime users of this product

Like the new Patriot Plus By Hankeroo

This is my third Mosquito Magnet. I liked the first one the best since it lasted longer than the second one. The moter died in the second one I had. I have has this new Mosquito Magnet Patriot Plus for just a little more than a month. Results are about the same as the last two. I have not changed out the propane yet so I don't know how well it works yet. The best thing about this one so far is how quiet it is. I have to get up to it to actually hear it on. That is a good feature since we are in the back yard a lot.

Q.The red light is flashing quickly which is the sign of a fault in the trap, according to the website. How can I determine the nature of this “fault”?

The first step is to check that there is propane in the tank. Trying a different propane tank will also often clear up this fault. If those don’t work, these steps may:
• Turn off the propane tank. While doing this, make sure to count and remember the number of rotations that it takes to close the tank.
• Disconnect the regulator and listen carefully – Is there a hissing or release sound?
• If you do hear that sound, keep the tank turned off, thread the regulator in and out of the tank, and listen for the sound again.
• Keep doing this until you no longer hear a hiss or release sound – it may take several attempts.
• Once you are no longer hearing that sound, go ahead and reconnect the regulator.
• Remember how many turns it took to close the propane? Open the propane now, but only 2/3 to ¾ of the way.
• It is very important to open the propane slowly. If it is opened too quickly, the tank will never be fully engaged.
Hopefully these steps will get your trap up and running. If not, please contact our Consumer Relations Team at (800) 953-5737 for additional help. much do u have to open the propane tank and what does the propane do?

We recommend fully opening the propane tank. The trap mimics a human by converting propane to CO2, with its patented catalytic conversion technology, in combination with a short-range attractant.

Q.Hello, I have a small outdoor space in an urban area. I have no idea where the mosquitoes breed, or what is upwind/downwind of it, and I don't have the space to place this 30-40 feet away from where people gather. Will it still work? Or will it just attract more mosquitoes?

If the trap is placed closer than 30-40 feet away from people areas, the mosquitoes will continue to go to humans for a blood meal rather than being attracted to the trap. We would like the opportunity to learn more and provide additional assistance. Please feel free to contact our Consumer Relations Team at (800) 953-5737 for further help.
