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 »

BUYER BEWARE -----Don't waste your money! I purchased a month before summer, spent over $450.00 with tax, and extra supplies. I followed every direction and it caught one mosquito. It constantly shuts. I have followed very thing to the T in the booklet and customer service went through the same thing I did and still same results. They will not accept a return or send a replacement. I have to now go the legal route

Worth every penny By Jim

Thought about purchasing a Magnet for years. I was very skeptical as to whether it would actually work. So many products and gimmicks on the market. After trying many different products and countless hours of spraying finally said it is time to try one. Well wish I would have done it sooner. It has been running now for roughly 10 days. It had mosquitos in it literally within minutes of turning it on. This evening we were able to enjoy sitting under our grape arbor until dark with no mosquitos. That was impossible before. So our experience with mosquito magnet is very positive. Would must definitely recommend this product.

Keep the buggers at bay By Pamelot

We had to replace our 2year old MM because it got hit by lightening during the storms this summer. We got it fast and didn't miss a beat with the mosquito problem We live in the woods and it would be miserable out here without our MM. Love it!

Useless Item - Useless Customer Service By John

Mosquito Magnet + 5 Months Use = ZERO insects caught. You've read that right. I was excited to try the Mosquito Magnet, and purchased it in Spring. It hasn't worked. It has not caught one single insect of any kind. I followed the instructions meticulously. I placed the trap in different locations. And still, I see mosquitoes hovering within 10 inches of the Mosquito Magnet with NOT ONE INSECT CAUGHT. I worked with customer service, and this is my experience: First, they re-sent me a PDF copy of manual (which I had followed). Second, I had to upload a video of it not working. Third, I had to PROVE to them where I purchased the Mosquito Magnet (I bought it on this website) with an argumentative Customer Service Representative. Fourth, I sent it in for repair. Fifth, their solution is "buy more of our stuff" to fix the other stuff that doesn't work. It's been an extremely disappointing waste of $300+ dollars, multiple tanks of propane, and hours of my time.

A Perfect Solution to our Mosquito Problem By SEMM

We live in an older wooded neighborhood in north Georgia and have alot of mosquitos in our back yard. We have tried a monthly spray service that was expensive and didn't work and another machine that ended up catching all sorts of bugs but not mosquitos. This Patriot Plus has worked miracles for us and for our next door neighbors! We knew the day the first tank ran out because that is when we began to get bitten. I had an issue restarting with the second tank and customer service was wonderful. They couldn't solve my issue but sent me a prepaid shipping label and I sent the top of the machine back on Saturday afternoon and had it back on Wednesday. It had a clogged hose that has been fixed and we are up and running again. I just texted my neighbor to let her know and she is as thrilled as I am! She has recommended this company to three people just by living next door to mine! That tells you something and the customer service I just received tells me an awful lot more. Thank you!

Works wonders By Hoy_Girl

The Mosquito Magnet works great! We can finally sit in our backyard for more than five minutes without getting eaten alive by mosquitoes. We would recommend it to anyone and already have.

Gets the job done By William

Fantastic product! Personally, I feel that the wired connection should be an option for the top tier models as well. However, the base model worked like a charm! Pay attention to the region and use the proper attractant. I leave it running 24/7during the peak months and I rarely get bitten.

Unit failed after 2 weeks By Richard D

I purchased the Patriot Plus online on June 28, and fired it up the following weekend. Worked perfectly for 2 weeks (trapped quite a few mosquitos), then stopped working. No fan, no ignition, no power to the unit. I contacted customer service, and they offered free replacement (since it was within 30 days of purchase), which I accepted. Because it is installed at my cottage, I asked that they send the replacement immediately so I could swap the new one for the failed one when I returned to my cottage next weekend, but they refused, indicating that normal procedure is to send replacement upon their receipt of the failed unit. They did agree to send the new one upon receipt of proof of return of the failed unit (via UPS tracking #), but that still results in a further delay in activating the new unit. Since mosquito activity diminishes significantly by mid August, the additional delay is significant. Since this is my 4th Mosquito Magnet, I expected them to honor my request to send out the replacement immediately. Disappointing response.

Q.If operated 24/7 approximately how long before propane tank is emptied?

We recommend to always keep the trap on during mosquito season. When it is run full time, the propane tank will need to be changed every 21 days.

Q.I live off grid and already have large LP tanks. Would I be able to use an adapter off of my main line?

This trap is designed for use with a standard 20 pound propane tank only.

Q.I have small dogs that spend a lot of time out in the back yard. Is this product safe for them to be around?

This product can be used confidently around pets.
