BiogentsMosquitaire CO2 Mosquito Trap - Sweetscent Mosquito Bait & CO2 Set - Effective Against All Species - Patio & Outdoor Mosquito Trap

We live in the the San Fernando Valley in Southern California and mosquitos have been really bad for us this year (I feel like location is important for people who are considering). I got fed up and decided to bite the bullet on this expensive trap setup after a family member let me know it was working for them (in another part of SoCal).In short... it works.What you see here is the first time I've emptied the trap since I set it up back on 8/26.I carefully removed the net catch last night (MAKE SURE YOU KEEP THAT LID CLOSED! I taped it beforehand to prevent any accidents), placed it into a gallon zip lock bag, and then placed the bag into the freezer overnight. The instructions say 2-3 hours will kill them, but like the line in the movie ALIENS..."it's the only way to to be sure."The results were shocking to be honest. It's a mix of all types of mosquitos, including the nasty Aedes variety. There's a large property behind my house whose owner leaves a lot of stuff around. My gut is telling me they're creating a breeding ground for these things in all the nooks and crannies of their junk.PROS:- Effective. That's all I want a mosquito trap to be.- Easy setup- The supporting bait packet doesn't smell that bad... at least compared to a typical water based fly trap.CONS:- Expensive initial investment, but it seems like this will pay off easily over time based on what I've been able to catch in a fairly short amount of time.- You must buy a cO2 canister. A 20lb tank (with a fill) ran me about $190 locally. $33 for a refill. I haven't needed to refill yet, but I'm guessing I probably will in the next week or so.- I feel like the trap itself is a bit over priced. I think $175 to $199 would be more reasonable.My setup:1) I have the cO2 trap and tank on a dolly that I cart around to different positions in the yard depending on the time of day/shade. Moving both individually is cumbersome with all the cables and tubing. A filled 20lb cO2 tank also weighs what feels like 50 pounds when filled – not convenient to move all the time.2) I set the cO2 regulator to release 0.5kg to 1.25kg depending on conditions. I pump it up during the late balmy summer afternoons with still, hot/slightly humid air. On days with more wind, I'll cut the cO2 back or not use it at all. With wind, the cO2 is blown around and is not concentrated near the trap.I wasn't going to buy the timer they sell for the regulator in the beginning (it's $95!), but now that I know this works, I'm going pick it up so I can have the cO2 release at specific times of the day.TIPS:1) Make sure you handle the included bait packet with gloves. It's oily and the smell of extremely dirty, sweaty gym stocks will linger.2) Consider a mobile setup like what I did to make placement and adjustment more convenient.3) Move the trap around. They love shade and I've placed it underneath a patio umbrella sometimes which I'm sure concentrates the cO2 a bit since there's now a 'ceiling' in that location.4) When power down the trap, the lid automatically closes because there is no longer any suction keeping the trap open. HOWEVER, one time it didn't close and the mosquitos that weren't fully in the trap FLEW OUT. Easy insurance that you don't let these demons escape is to use some masking tape on the lid handle to secure it BEFORE you unplug.

Update-8/1/2024:The CO2 tank finally exhausted on this, and I upgraded to a 20 pound tank. I still stand by my original review that this thing is amazing. However, saw it for a few days without the CO2 tank and, while it still works with only scent packets and catches mosquitoes, after I refilled the CO2 tank and reattached, it is crawling with mosquitoes. Totally worth the purchase.Original Review:I've tried everything in my backyard. Mosquito coils, foggers, and even buying targeted insecticides that are supposed to limit mosquito egg development. However, at the end of the day, unless I made sure that I was covered head to toe in high intensity mosquito repellent every time I walked in back, I would get destroyed by mosquitoes. Putting repellent on is fine, but if I would go outside and want to weed for 20 minutes and forget to Put on repellent , I would come back inside and be itchy.I've been looking at this thing for a year and the cost Had really put me off purchasing it. After another crazy spring here in New York, I decided just to bite the bullet and try this though.I'm totally blown away. When I first bought it, I only had the scent packet in it because I needed to wait to find a place where I could source CO2. Even with the scent packet, it caught a good deal of mosquitoes though. However, once I got CO2 attached to this and placed it properly, I haven't had a single bite in the week that I've had this installed. I pull out the bag every day to see how it's doing and the bottom third of it is just filled with mosquito corpses now. We have tiger mosquitoes and the other normal brown looking mosquitoes and I see both of them in here dead.Tips:1) Place it properly. I have an extension cord running from an exterior outlet and I run this into a corner of my yard where it's hidden behind some foliage in a spot that's shady.2) Just commit to buying the timer for it so that it's only pumping out CO2 at the most opportune times to target mosquito activity. That's pretty important to cut down on how many times you need to get the tank refilled.3) just buy a 20 pound tank and figure out a way to have it be easily refilled. I think what I'm going to do is just have a delivery service that comes and picks up the tank every two months when it runs dry and give me a refilled one since I don't have a car and getting into a welding shop to have it refilled would be kind of a pain. Where I live in New York, the mosquito season is about four months. So using the regulator where you time it to come on only at very specific times when the mosquitoes are at their worst, I calculated that I'll spend about $160 a year to have the CO2 replaced. In the grand scheme of things when you think about having to constantly buy repellent, it seems like a worthwhile fixed cost. However, yes, if you live in an area where mosquito season is pretty much all the time, that might not work for everyone financially. For my situation though it's perfect.Yes. You'll need to commit to spending about 400 bucks for the machine itself, the CO2 regulator and your first filled 20 pound tank. However, if you can stomach that initial cost, I don't know of any better system that exists on the planet to keep your Backyard mosquito free .Some people have talked about taking out the bag of mosquitoes and putting it in the freezer to kill them periodically. I guess you could do this, but I don't really see the point. Once they get in here, they're completely trapped due to how the bag is designed (a cone arrangement that mosquitoes can't find their way out of once they're in) and if a mosquitoes trapped in here for two days, it dies on its own due to dehydration. I think it's likely big enough to just leave the bag in here all season and just empty out all the corpses at the end. Less maintenance too.Another thing. Zappers aren't a great technology to get rid of mosquitoes. Mosquitoes aren't attracted to light and bugs zappers kill a lot of other insects that I'm not interested in killing. This thing is super targeted, the only bugs that are trapped in here are mosquitoes.Buy this. You won't regret it. Completely sustainable and you don't have to use poison on your body and your yard to try and attempt to keep mosquitoes off of you. I'm not quite sure what the other reviews are talking about. If you follow the directions and run this thing the way it's supposed to run, you'll be able to live in normal life in your backyard again!

Leave it to the Germans to invent a scientifically effective solution against mosquitoes, this really works! (Check the website with all the scientific papers) I’ve tried many, many solutions, from an anti-mosquito spray every month (didn’t work, very expensive), to Thermacell (moderately effective to repel, but not enough, and I used 2 at the same time), Spartan mosquito tubes (useless), etc. I installed the Biogents solution with CO2 and and attractant that simulates human skin (smells nasty so put it at a distance), and it’s very effective, after only 24 hours I’ve collected a good chunk of all of the mosquitoes in my backyard. (Assuming 1,000-3,000 mosquitoes per acre, adjusting for the size of my patio area of ~500-1,000 sq ft about 40-80 mosquitoes). Now this is quite an investment, the Biogents is not cheap, and it requires a CO2 bottle (buy it second hand on eBay and go to your local plumbing shop or beverage supplies store, or Airgas to fill up / exchange with CO2). For a few weeks you’ll use 1 lbs of CO2/day to suck up most mosquitoes, then you can buy the CO2 timer that opens the CO2 line only at dawn and dusk when mosquitoes are most active. Added a picture, it’s hard to see but there were dozens of mosquitoes trapped at the bottom. Lastly, this is a non-toxic solution that doesn’t kill lots of other beneficial non-mosquitoes, which is what the electric zappers mostly catch (also useless against mosquitoes + very loud). If you’re serious about mosquito eradication, get this. BTW, supposedly a cheap box fan can also do the trick, because mosquitoes are bad flyers, but I’d rather eliminate them given the fact they spread diseases and the Asian tiger mosquito aggressiveness. Bottomline, I got my yard back and my kids playing outside again, success!
