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 »

Hard to turn on By Jared
It’s great when it I can actually get it to turn on. But once it runs out of propane and I have to restart it, it literally takes me 10-20 tries to get it running again. I’ve read all of your support page, called your support number, and watched videos on YouTube.

Poor Quality and Reliability By JPUCK

Poor Quality and Reliability is all I can say. Unit only lasted one season and now doesn't work. Even when it was working the unit is constantly shutting off and has to be restarted.

Response From Mosquito Magnet®
Kathryn : Consumer Relations Representative

Thank you for sharing your feedback. Traps should run consistently as long as there is propane in the tank attached to them. Typically, a 20 lb tank will last between 18 and 21 days. If a trap is turning itself off more frequently than this, please contact us directly at 800-953-5737 for troubleshooting assistance, we're happy to help!

It works with some locating efforts. By Deano

I’ve had it here in Coastal Florida for almost a month now. The propane tank went out today. It lasted 25 days. I only checked because this evening we noticed no- see-ums again. It did take a couple weeks to really see a difference but it made our outdoor life much more pleasant. I changed tanks a half hour ago and once again it’s pleasant on our lanai. We did have to move it several times to find the place where it was most effective. Four to be exact. My wife ie happy. End of story.

awesome By Tom

In the first couple of weeks, I have watched the bag fill with more no-see-uhms then I could imagine. I was able to wash my vehicle with a noticeable difference of not waving of the flies and mosquitos. Glad I bought it.

Well worth the investment By Robert
It works as advertised. This is the second one that I have purchased and it cuts down on the mosquitoes tremendously. We are able to enjoy the outdoors again without having to use harsh chemicals and sprays.

Q.Where should the magnet has to be placed in the backyard?

The trap should be placed 30-40 ft away from where people congregate, upwind of where mosquitoes are breeding.

Q.It says this will start showing results in 7 to 10 days. I was considering using this for camping trips, but it sounds like this would be ideal for this?

This trap is not recommended for use in temporary locations.

Q.Unit worked for one week. Relocated and then the unit stopped working. Light flashes as expected but rather than turning to solid light after a while it starts flashing even faster and stays that way. The unit does not start working.

Please contact our Consumer Relations Team directly at 1-800-953-5737 for troubleshooting assistance, we're happy to help.
