$30 DIY Box Fan Mosquito Trap - VERY Effective

[@kyleharrold5749]

I got a $60 ebay fan does 3000 cfm. it eventually pulls their dried dead bodies through the mesh, usually leaves the legs behind. some yeast and sugar water in a large container makes CO2 and a cheap amazon mosquito bait gets about a hundred a night. hard to count just by legs though.

[@williammcdonough6342]

Thank you! I've seen a couple videos about these fan traps and wanted to believe them. But one thing just always seemed to not make sense: What draws the mosquitoes to the fan's intake stream? Your suggestion of yeast and sugar-water to generate CO2 was the missing piece of the puzzle! So, thanks again. I'm setting one up tonight!

[@Mixinnitup]

@@williammcdonough6342 you can also jist use carbonated water. Shake it and then drill a small hole at the top.

[@therockindoc5453]

Brother, Can't thank you enough for this simple, easy and effective way to get rid of mosquitos. They eat me alive and I hate 'em. Payback is a Bitch!!

[@TheZzzzzzzz]

Grandpa had a squirrel cage fan up by the light in the barn with pantyhose he used to feed the bugs to the pigs I remember it was always full this was back in the 70s lol

[@aprilirvin6186]

best video i seen on really ruining mosquitos day . i have to try this as much as i hate mosquitos .

[@rolandoperez8054]

Wow. Shut off the fan first before spraying

[@johnjacobjinglehimerschmid3555]

Why put the screen under the fan grate? Just make it a bit bigger and use magnets to hold it to the case.

[@therombaro]

John Jacob JinglehimerSchmidt Unless you dont have magnets, which, I didn’t. This was easier since the covers are already off - just roll the screen over one side, reattach the fan guard, and cut around it with a knife

[@space6irl]

Genius!! Thanks for the video

[@collinvalerie6443]

😊I’m 😊

[@FayeGotFaded]

Can you make a step by step instructional video on how to make this?

[@guitardaddy6]

? You can't see it and make it. Men can. You should show your man who you are surely loyal to. Clean his house and cook his food so that he can build this kind of stuff for you.

[@dardachang5097]

Jonathan, you mentioned about each fan about $9 from HEB. Would you mind sending a link here? What is the CFM for one fan? I am thinking to either buy one or build the one like yours.

[@chrisgraham2904]

Yeah, that fan is $66.00 each on Amazon Canada.

[@adrianbradshaw4956]

Watched in Corona filled 2020 and you spritzed about $10 of rubbing alcohol on those skeeters

[@PolarIre]

Windex would probably work just fine. Makes wasp fall to ground immediately, same when I spray a fly with dawn dish soap spray. Lol poor bugs.

[@lucybellescott7531]

Wow .. next you need to make a video of step by step on making this contraption.

[@therombaro]

It is pretty straightforward. All you need is a screwdriver. 1. Take all the covers off the fans with a screwdriver. 2. Lay them flat on the floor, and stack one on top of the other. Make sure the control knobs are both on the same side (so you dont end up with fans blowing in opposite directions). 3. Reusing the same screws, you can screw the fans together through the holes normally used for the covers. Nothing fancy required, the screws and holes are already matched for each other. 4. On the intake side - aka the sucky sucky side, not the blowey blowey side - lay down a roll of window screen cloth. Cut it to size, and use packing tape (or any tape) to stretch it tight over the intake. 5. Place the guard cover / grate over the window screen, and screw it back in. 6. Replace the other guard cover on the exhaust side - the blowey side. Some fans work well enough where you can put the screen on the outside of the guard grate, and attach with tape or screws. That makes it easier to clean, but can also look ugly if you’re the type to care about such things.

[@THEGABNER]

Do you ever see them alive on the screen if you don't spray them with alcohol? Seems like the screen is overkill and the fan alone would kill them, they're pretty delicate. You're a smart guy I enjoyed your video, thank you.

[@therombaro]

Oh absolutely they’re alive - if I turn off the fan a whole cloud of mosquitoes flies off and attacks me. The fan itself doesn’t really kill them very effectively, but it WILL relocate mosquitoes to wherever the fan is pointed, so it’s almost like a mosquito gun without the screen.

[@therombaro]

One thing i’ll add, over time the mosquitoes dry out and die on the screen, so at any given time they’re not all alive, but enough of them are alive enough to warrant alcohol.

[@travisburch4342]

This is great -- do you put anything in the water to kill the mosquitos?

[@therombaro]

Travis Burch Mosquito dunk

[@bella50008]

Thank you!

[@emilybradley3821]

I really like this. Do you have a screen on both sides? Or just the side they're getting sucked into?

[@therombaro]

Emily Bradley Just the one side

[@bif90210]

your kidding right??

[@bpapao]

now those 9 usd fans are 22+! thanks biden

[@ATM589]

wow

[@Kidd-nq4fg]

Actually if you just use both fans individually you’ll end up trapping more skeeters, lemme tell you putting them together like that doesn’t make them more powerful or anything like that. If ya want some more power get you some vintage box fans.

[@lovelydelrey]

damn we love to see it

[@AlexGarcia-gw2cy]

How long do you run the fan for? Seems like it would use up a lot of electricity, or maybe not.

[@Eagle-md6ku]

about 71KWh per month per fan. A few dollars per month running 24/7 ($10-$20)

[@kc-jm3cd]

You could probably rig solar setup

[@gyuri911]

Great, but why not just electrify them instead of alcohol?

[@therombaro]

Because simplicity

[@johnnygraves7573]

Wouldn't the fans shred the mosquitos as they go through normally?

[@therombaro]

Johnny Graves Not nearly as reliably as one would hope. The screen is far more effective at capturing and killing, which is why I added it.

[@oskardacat6748]

Is the fan pointed towards or away from the water?

[@therombaro]

away, so the water is on the suction side

[@Spore20Esq]

I'm going to assume if you didn't spray it with rubbing alcohol which is a seemingly pointless step they would shake free pretty easily

[@capt.k4367]

I used a 1-fan version of this trap a couple of years ago and as soon as I turned off the fan, several mosquitoes would fly away. So, I sprayed the screen with flying insect spray but they still didn’t die! I wish I’d thought of rubbing alcohol back then.

[@nahnope8581]

Whats so pointless about it lol? it kills them

[@stephenmayer9228]

Do you need both fans to trap mosquitoes? Wouldn't it work with just one fan?

[@therombaro]

Stephen Mayer One fan doesn’t really hold them to the screen well. I’m still using this fan out by my grills for smoke and bug control. I’m actually considering adding a third fan. More fans equates to better suction and thus, bigger bugs

[@gacputech7719]

​@@therombaro Thanks for making this great video. Instead of placing my screen on the input side, I placed my screen under the grate as you did, but on the exhaust side, and with the extra airflow against them, they can't fly out and back through the fan blades.

[@littlebrookreader949]

👍 👍 👍 👍 👍

[@User-si4us]

Nice video. Do you think this can be used indoors?

[@therombaro]

I do it all the time! Useful for drying up spills on the carpet

[@josephballard8404]

Kind of sounds like you are whispering...please speak up a little in the future! Thanks for the content!

[@truthorhappiness]

I wonder if anyone has ever snorted powdered mosquito 😂🤮🤣

[@Mixinnitup]

Be the change that you want to see in the world

[@therombaro]

I just snorted a line of mosquitoes... I met Jesus.

[@Threedog1963]

How long did you run that to get that many mosquitoes? I think I'd pass on turning it into a bug zapper, as it probably isn't necessary. They seemed dead enough already. Plus, when they get zapped, wouldn't the screen be harder to clean?

[@therombaro]

Threedog1963 this is two days worth

[@therombaro]

Threedog1963 As for zapping, I would use a larger gauged hardware cloth, so the idea is zap em and blow em through. Most of them. Of course, then it would look like a mosquito beach at Normandy before long.

[@Threedog1963]

I forgot about the fan blowing through the zapped mosquitoes. I was just remembering my old zapper where the mosquitoes would just sit there and sizzle, their guts popping onto the grid and gluing their dead carcasses to the metal grid. I picked up your link from the Next-Door app so, we're neighbors and share the same mosquito problem. Thanks for posting there and here.

[@therombaro]

Threedog1963 I went to Lowes, not a single person knew what hardware cloth is. I got sent back and forth three times and finally gave up.

[@Tara-sf7uu]

@@therombaro at lowes the hardware cloth is usually in the outdoor lawn and garden with the rabbit wire fence and short rolls of hex fence

[@doorstoafrica2427]

where did u get the fans from again/

[@therombaro]

doorstoafrica HEB

[@mauricioochoa5519]

I think he said HEB, a grocery chain in Texas.

[@ROMANEMPIRE69]

You know what else works and is fun. The new bug-a-salt black fly edition. Of course you have to hunt them down and shoot them when they land. Or if you have a good aim take them down in flight. 🤪

[@therombaro]

I just bought a Bug-A-Salt, I use it for snails and slugs.

[@huckbeduck]

I chased mosquitoes down with a blow torch the other day, very satisfying! Except for making the shed too hot to work in though. Seeing the bastards curl up and fall out of the air was great
