Mosquitos have only been a problem in Newport Beach for the last couple years when Asian Tigers moved in, always biting your ankles at any time of day or night. We tried several traps and other items to keep them away and finally bought two real traps, Mosquito Magnet and Biogents w/ CO2. We have one set up on each side of the yard about 20 yards apart.
Biogents runs on CO2 and catches a lot of mosquitos, I think quite a few more than the propane based Mosquito Magnet. In the pics above you can see there are still 20-30 live mosquitos in the Biogents trap that have been caught in the last couple days and loads of dead ones from over the last month. The trap of the Mosquito Magnet only has a couple of live ones but it too has killed hundreds over the last month. Kind of hard to see the dead ones in both traps in the pics but must be around 1,000 combined. So Biogents catches more here at my house. Only issue with Biogents is the cost. Both items are around $300 but the Biogents uses a CO2 canister that costs over $100 and costs $35 to fill which lasts about 5 days with a 10 gallon tank (around $200 per month). Mosquito Mag uses propane so buying the tank is only $40 and $22 to fill up PLUS it lasts a full 20 days and you can find propane anywhere (around $30 per month). The convenience and cost to run the Mosquito Mag is much easier to live with over a longer period of time and it does do a good job. If you can afford the CO2 Biogents and have easy access to refill CO2, it kills more. I'm going to keep running both until we clear the area then might just keep the Mosquito Mag running long term, bringing out the Biogents if we notice more mosquitos again down the line. Either item is great and way better than anything else we tried. Very satisfying to see 1,000 mosquitos in the trap versus biting us inside and out.

I was cautiously optimistic considering the amount of negative reviews. But I am glad I pulled the trigger on this device. It does work. In about 25 days it caught 1896 mosquitos and destined them to suffering and death. Yes, they die of dehydration. It is a slow and painful death but these bloodsuckers totally deserve it. They think they going for a feast, but they commit suicide by getting into this machine. Make sure you use fresh lure. Without it the effectiveness of the device is about 1/20th. I tried with and without lure and you can trust me on that. Location - central Michigan, September 2023. Next year I am installing it right in early spring to make sure I destroy the population before it reproduces itself. So far no issues with firing it up, but I only used it for about 25 days and changed one propane tank. I know a lot of people had issues with starting it over time. But I am ready for cleaning it, when time comes.

P.S. if you wonder who I counted the catch - I just happen to have a VERY precise lab scales.

This product works great to trap Aedes Egypti mosquitoes as long as you are willing to put the time in ( the invasive ankle biters in Southern California) This type of mosquito is attracted to heat, CO2 and the bacteria on your feet. The Mosquito magnet makes the heat and CO2. I use my teenager's dirty socks in a small plastic bucket underneath the vacuum device to increase my yield. This is cheaper that the Sweet Scent cartridge that you can buy and it works great. I switch the socks out about once weekly. A standard proprane tank fuels the device for about 3 weeks then needs to be replaced. It's a little tricky to get the device restarted once the propane is switched. Maybe due to air in the line? I need to fiddle with it a bit. Also make sure the basket is fully seated in the device or it won't work.
with all this effort, last season we had THOUSANDS of the mosquitoes in our two traps. Even the county vector control employee was amazed. Made a big difference in how time we can spend in our yard during the summer. Expensive to keep up with but worth it for us.

The Patriot Mosquito Magnet does an excellent job, killing a rounded sandwich bag full of dead mosquitos. However it would not restart after the first two propane tanks (40) days! My previous Liberty (MM) lasted 15 years and thru maintenance I kept it running before it finally gave out! I think the Liberty finally stopped working because the catalytic converter was spent. The maintenance is not the fault of the Patriot (MM), it is the fault of the propane. Propane is a dirty gas and over time it will plug the burner orifice with a tar which in the presence of heat does not flush out with the "Quick Clear Maintenance Cartridge". I feel these cartridges are a waste of money. You must disassemble the (MM) to remove the burner nozzle and soak the parts in lacquer thinner for 30 minutes. You must remove the cover screws, unscrew the base of the (MM) and lift up enough to remove the fuel valve, unscrew the fuel valve hose and finally remove the burner nozzle. Disassemble the fuel nozzle and soak in lacquer thinner. It took me 1 hour but the next time it will be only 30 minutes since I will know how to do it. Also, to save time, all screws were put back lightly, not tight. I did not reuse the screws on the cover because I want to just lift it off. It will not blow away. After all this, I pushed the start button and away it went for I suspect another 40 day operating period. As I said, you must learn how the (MM) works, how to take it apart, clean it and reassemble it. You have to void the warranty to fix it yourself. The warranty will finally run out anyway, you might as well learn how to fix it yourself from the start. If you do, you will be rewarded with many years of killing thousands of mosquitos! Obviously in addition to cleaning the (MM) the following parts may fail with use: the igniter, temperature sensor and the plug in power supply (12v). The key here is to avoid shipping the (MM) for repair. It will eat you alive with repair charges. Good luck, Ed

We live in Southern California and for the last few seasons we have been bombarded with the Asian Tiger Mosquito. It hunts at all hours of the day and night. No more leaving the patio door open on hot summer nights and forget about sitting still in the backyard when the day has come to an end.
That is, until we bought the Mosquito Magnet. It's been 1-1/2 weeks and I am now able to take a seat on my patio and rest without worrying about getting attacked by hundreds of those little bastards. It's been a blessing. It's not a 100% cure though. Occasionally I will look down and find one bouncing around waiting to make her move. I'm hoping that it keeps working. Fingers crossed. The basket probably has 50 mosquitos in it at the moment. There's begun to be a pile of dead ones in the corner of it. The person who recommended it to me suggested that I purchase a second filter basket which was some good advice. When the basket is getting full, you have to take it out and empty it. But if there are live ones in there you can't empty it out. That's why you need the second basket so you can swap them without having to let the live ones get away.
*I will try to do an update in the future to let everyone know what my thoughts are at that point.

According to the website, the second round of hatching mosquitos should have been over but we're still seeing tons hovering around the Mosquito Magnet and occasionally getting the stray that bites.
A good tip that I've learned is to take a shirt that you wore all day and put that below the vacuum part of the machine and you'll see the numbers of mosquitos hovering around it increase dramatically. This thing definitely works but I don't think it can control an acre if you live in a crowded city and not able to keep track of whether your neighbors have pools of water sitting around. At this point I would say that I was hoping for too much but still believe it is a good investment.
