Quick and Dirty Mosquito Trap
Update: I have contacted our Chinese speaking DIY:happy operative Shana from iRocks for a more accurate translation. Turns out I was way off, so check out the updated and translated instructions.
How to build a Mosquito trap.
Materials Needed:
2000ml (2 liter) bottle
50 gram (brown?) sugar
1 gram yeast
Thermometer
Measure cup
Knife
Black paper
1. Cut the top of the bottle as shown
2. Put 200ml hot water in the bottle, stir with 50gram brown sugar. Put the sugar water in cold water to cool it down til 40C (temperature).
They use a bigger container with cold water - put the small cup that they use to make sugar water in that container and that stick is a thermometer because they want the sugar water to cool down to 40C (temperature).
3. After cooling down, put the sugar water in the bottle then add the yeast.
No need to mix the yeast with the sugar water. When yeast ferments, it creates carbon dioxide.
4. When you cut the bottle, dont throw the top part away because that’d be needed for step 4 - you see they put the top upside down to fit into the bottle.
Carbon dioxide will be released from where we drink the bottle so make sure to seal the edge.
5. Put black paper around the bottle since mosquitos like dark places and carbon dioxide. This mosquito trap will then start working.
Mosquitos fly around the corner, so the best place to place the trap is at some dark corner.
TIPS: Put the trap in some dark and humid place for 2 weeks, you’ll see the effect. You’ll have to replace the sugar water + yeast solution every 2 weeks.
Here’s a link to the original Flickr photos.
Update: The idea is apparently from a school class in Taiwan. They invented the trap through trial and error. Here is a link to the class’s website.
Many commenters have noted that this DIY mosquito trap doesn’t work in all areas (or on all species of Mosquitos). Check out Mega-Catch mosquito traps for a commercial solution with a wider effectiveness.

It looks like this would also work for yellow jackets (meat bees). Put sugar based soda, and or rotting meat for bait. On a related note to kill the nests, WD-40 works surprisingly well. If you’re bold, do it in the day time. Otherwise, after dark they’re more likely to be at home and inactive. One squirt will do it.
My Chinese isn’t perfect, but I still understand a bit. This is actually a recipe for Fuzzy Navel Daiquiris. Understandable mistake, considering the navels in China are miniscule and black.

mosquitos indeed are attracted to carbon dioxide, as it would normally lead them to prey (think: herd of animals).
another good source of CO2 for short-term occasions would be dry ice, available from many companies that distribute ice (the normal frozen-water kind).
if you’re having an outdoor party and you pick up ice (the normal frozen-water kind) from one of these companies, pester them for a chunk of dry ice to boot.
then put it in the most remote corner of your yard. it will draw the mosquitos to the melting dry ice and away from your party guests (think: herd of animals)

MacGyver Tip: DIY mosquito trap…
The DIY:happy blog has translated a Chinese tutorial for building your own mosquito trap out of a two-liter plastic bottle. After cutting up the bottle just so, mixing in a sugar water/yeast mixture, and covering the bottle with black……
how much yeast??
jh,
From scanning the text below Step 1, I would guess that you’d use 1gram of yeast.
JZ
That’s right, 1 gram of yeast. I updated the tutorial with a proper materials list.
Great idea. Regular sugar will work fine, yeast doesn’t care what it eats.
Without a scale, how would one measure 1 gram of yeast? I’d love to try this, but 35 thousandths of an oz is a tough measurement. Ideas?
One gram is 1/28 oz. About three tablespoons should do it.
My Dad used to get rid of hornet’s nests by getting a propane torch out and a garbage can. You place the can under the opening to the nest, at least two feet. Fire up the torch. place the torch 1 inch from the bottom of the nest opening, parallel to the ground. Give the nest a good jolt. As the hornets or wasps fry out to engage the enemy, the heat from the torch burns off thier wings in an instant and they fall benignly into the trash can. pour water in to kill them off et voila.
Not for the faint of heart.

Hi Guys,
This idea is from a Yun-An primary school Taipei, Taiwan, not from China. The childran were doing the science expriment with their teacher. In the very beginning, the expriment was using soap water only.
The basic idea is that CO2 in the trap will attract Mosquito. And the CO2 is generated by the suger water and yeast. According to the instruction, you have to mix 200ml water with 50q granulated suger first, and then shed yeast on the suger water.
It also says that you shall replace a new trap every month.
Don’t forget to cover this trap with black paper. Since mosquitos like dark color.
The same idea is used to feed CO2 to planted acuariums.
I have been making CO2 reactors for a while and you don’t need the thermometer, just disolve the sugar and add the yeast, no hot water needed.
Shane (#19)
“As the hornets or wasps ‘fry’ out”
Was that a freudian slip, or what?! *grin*
The change in water temperature is for the yeast - you’re right that it’s not needed, but yeast is more active right around 40C. I do this same thing when I make bread - heat up the dough before I put in the yeast to make it more active - and I get nice fluffy bread every time!
the reason for the brown sugar is that it makes a stickier concoction than refined white sugar that will make the mosquitos stick better
what if the brown sugar concoction attracts ants? How do I get rid of the ants?
add some borax, that might kill the yeast though.
For the ants, place the mosquito trap in a shallow pie pan filled with water. The ants can’t get to the food source then. Of course, if the ants are over in the corner, they’re not bugging your party guests either.
Wow, great idea! Then we can have the mosquitoes laying eggs in the shallow pie pan, and as they are capable of flying, they get stuck into the trap! Might want to add some viagra into the sugar/yeast mix too if you’re going to add borax.
A few comments:
* The amount of yeast isn’t terribly critical, as the yeast will multiply in the sugar water.
* 1 gram is probably a reasonable amount, which, as somebody said, is about 1/28 of an ounce.
* The little packets of yeast for baking bread, like Fleischmans (sp?), Red Star, and similar are 1/4 of an ounce. Pour a packet out and estimate 1/8 of that. Next time, just guess based on what you just learned.
* Three tablespoons of yeast is far too much (a waste of yeast).
* The most important thing about the yeast is to make sure you don’t kill it with water that is too warm. It doesn’t take much–I think a temperature of around 110 degrees F (~ 45 degrees C) will kill the yeast. Most tap water is quite a bit hotter than that and will kill the yeast.
The actual amount of yeast isn’t really that important. Just dump in 1/2 a foil packet, or about 1/2 as much yeast as is in a packet of sugar. Once the yeast starts to reproduce they will breed to capacity.
Yeast needs oxygen to reproduce, so you might want to shake the water in a jar or can or something, just to mix in some air. Whatever you do, yeast a hardy organism so you shoulnd’t worry too much about it. Just dump it into body-temperature water and you’re off…
The only problem I see with this little invention is maybe you can get ants attracted to the sugar water.

3 tablespoons of yeast = 1/28 oz. ? That the hell are you talking about?
Instead of sugar water, could you just leave some Coke left over in the bottle?
Kaycee,
Good question! I was thinking the same. Fresh Coke would supply CO2 as well as sugar to jump start the process. Only question I have would be whether the acidity of the Coke would harm the yeast? Any brewers out there care to comment?
Has anyone tried this and can report problems with ants? The yeast may keep them away.

Add a computer muffin fan, duct tape(of course) some tubing, a funnel as venturi…cobble together the fan to disperse the scent, the funnel to direct the flow of air over the scent and up into a catch area. I’ve just saved $200!
“What traps the mosquitos?!? Are they too dumb to find the opening they just flew in through? Is there a missing step?”
No missing step John, insects really are that stupid. Sure, a few might figure it out by fluke, but the majority will stay there till they die.
A few people have reported trying this to great success. One lady set up 5 traps around her home and they were all full within two days.
Ants won’t cross a film of petroleum jelly, so just run a ring of it around the outside of the plastic bottle just below the lower edge of your black paper.
Don’t dump out/renew the mixture every two weeks. You have a healthy fermentation going, so why not exploit that? Pour most of it out, then just add more sugar water.
Actually, the optimum temperature to bloom yeast is in water at temperatures of 110-115 deg F. Yeast begins to die off at around 140 deg F. The general rule of thumb is that for every 17 degrees up or down you go, the yeast will either double or halve its activity, respectively.
For a totally maintenance-free solution, forget about goop-filled plastic bottles and set up a bat house instead. A single bat eats up to twice its own body weight in insects every day. And they’re fascinating to watch.
TIP: Don’t put it where raccoons can get at it, or you’ll just end up with a sticky mess.

We used to do something similar to catch fruit flies in the house. We used cider vinegar, if I recall, which is basically just the end product of yeast reacting with sugar water (apple juice) anyway.
To repel ants, essential oil of peppermint is what we use around our house. Cheap (you just drip a little where the ants come in), non-toxic (though don’t drink it) and smells good.
To repel mosquitoes, spray or rub a little of a mild solution of essential oil of catnip (Nepeta cataria) on yourself. Good carriers include (from best to OK), fractionated coconut oil, cosmetic alcohol (sold as perfume base), unscented hand cream, unscented massage oil, unscented cooking oil. I live in Texas and am tormented by mosquitoes every year, but this works great. Use a teaspoon or two in a pint/half-liter of carrier.
The key, by the way, to the funnel trap is that the bugs have the smell to guide them in, but nothing to guide them out.

Re: other insects
YELLOWJACKETS, HORNETS, ET AL–Just pour gasoline on their nests. No need to light it. The vapors kill instantly. Very useful with ground nests, as garden hoses do little more than annoy them. Gas is also cheaper than W40, or at least it was before the war heads screwed up the well heads.
ROACHES–Very tough nut to crack. Use a pincer attack. Boric acid does work and VERY well. However, you have to attack them where they live or enter the kitchen. For example, they LOVE the insulation of refrigerators and live by the hundreds in your fridge walls. Hence put boric acid under the refridgerator.
Second, they love to live in between walls and in cracks. Hence you have to seal every pipe fitting leading into a wall. You also have to seal every crack that joins a cabinet, vent, window, etc. Last but not least, deprive them of all food by washing dishes instantly, keeping garbage in tight-lidded containers, and throwing out brown-paper bags (yep, they eat’em).
In sum, this beast merits respect. It has not changed in 200M years, because it is more perfect thant the Alien. It can subsist on the insulation of wires. It is fast, stealthy, and cunning. It churns out young’uns like a hamster. It is destined to take over when we our done screwing up the planet.

I converted the recipe into English measurements. Also used the “hot to the inside of your wrist” water + yeast that we use in our bread recipes (no need to measure).
DIY MOSQUITO TRAP
Ingredients
2-quart soda bottle
1 cup water
4 Tablespoons sugar
1 packet dry yeast
Knife
Black paper or black plastic garbage bag
1. Cut the top off 2-liter soda bottle. Set the top of the bottle aside for later.
2. Microwave or heat 1 cup water in a glass bowl or glass measuring cup until it is boiling. Stir 4 T sugar into the boiling water and stir until sugar is dissolved. Let this mixture cool until it feels warm when dropped on the inside of your wrist. If the water is too hot, it will kill the yeast you will add in the next step. If it is too cold, the yeast will not grow.
3. Pour the sugar water in the bottle, and then sprinkle the yeast on top of it. Do not mix or shake the yeast with the sugar water. The yeast is going to ferment with the warm sugar water and bubble up, creating carbon dioxide.
4. Place the cut top of the bottle upside down into the bottle.
5. Cut and tape black paper or the black plastic all the way around the bottle. Mosquitos like dark places and carbon dioxide, so place the trap in a dark corner.
One full packet of yeast is one tablespoon. That’s too much. To avoid waste, just use a good pinch and store the rest in the refigerator.

How to build a Quick and Dirty Mosquito trap.
……
for reference on the yellow jackets, just cut the bottle and invert the top the same way. Then put popsicle stick legs around the cut portion so that when the bottle is placed upside down on the ground it stands 2 to 3 inches above the ground. Then set the bottle over the entrance to the yellow jacket nest. No need to add anything to the bottle. The yellow jackets can fly into the nest (because of the popsicle stick legs), however when they fly out some of them will fly up into the bottle and are unable to escape.

roach killer:
i’m going off of memory with this so someone may need to help me out with this. take a small bottle cap, wider than a 2 liter pop bottle or even a milk jug. well something between an inch and two in diameter. fill it halfway with either baking soda or baking powder (this is the part I dont remember), next top off the bottle cap with plain sugar. you probably should place an unfolded newspaper underneath this filled bottle cap on your kitchen floor. leave it overnight. the next morning you will have roach pieces all over the floor. the roaches are attracted to the sugar and eat through it to the baking (soda or powder). they cannot get rid of the gas in their stomach’s and explode. i’ve seen it myself. works like a charm, but i cant remember which (soda or powder) to use.
“Sugar in the Raw” is brown colored big crystal sugar. They have it at Starbucks and the Coffee Beanery.
Hi, doing a little homework, I find that the measurements for the mosquito attractant solution convertsin US measurements roughly to:
3/4 cup water
1 teaspoon yeast
1/4 cup packed brown sugar.
My little postal scale doesn’t go all the way down to 1 gram accurately, but is a solid 10 grams equal 10 measuring teaspoons full. Now that I’ve got out all the stuff, guess I’ll finish this experiment, and try it out…..
A whole packet of yeast is too much. It bubbles out of the top of the trap. Use 1/4 or less.

From an old Scientific American article, I remember that mosquitos buzz around fairly ranfomly till they find the combination of moist air and carbon dioxide, and then they go into a spiral motion, going down as long as they smell the combination.
This leads them to spiral down into the funnel into the water. There they get stuck by the stickyness of the fluid, or can’t find their way out the small opening because they try to climb out vertially and would probably miss it. Even if they did, they might try to dive back again. Also, the concentration of CO2 in the bottle would make the mosquitos pass out after a while as they need oxygen to live.
The advantage of the sugar and yeast, is that it generates moisture and gas fairly continuously, while baking soda and vinegar would not last long.
If I remember correctly, five grams weighs about the same as a US nickle of 5 cent piece.
Has anyone gotten this to work yet? I think I followed the directions properly and even after a few days it certainly spells like its producing gas. I used 1cup water, 1/3 cup sugar, teaspoon of yeast.
But no mosquitos in the trap.

You should probably cut the top of the bottle after where the curve stops, since it falls through the wider bit of the bottle if you cut it short.
Molasses heavy brown sugar is probably stickier to keep the bugs in.
A clear bottle will look better than a green one.
You can spray paint the top instead of covering the entire thing in black paper. Spray paint is a bit more messy, but its permanent. The top will attract the bugs, while the bottom can remain clear I’d imagine.
Use new yeast. Old yeast may have died entirely. I’m going to use old yeast since I’d like to be rid of it, so I’m going to use extra in case 90% of it is dead. It only takes a bit living when you’re dunking it in sugar water, it will multiply to take advantage of the sugar (food).
Caulking can seal the lid and stick it on, but it’s more permanent. Not sure how I’m going to empty it now without breaking that seal.
This is a cheap trick. If it works, a more permanent solution would be better. For example, using a larger box instead of a bottle, one with a valve at the bottom to empty it. Spray paint the top to make it black and permanent. This can probably be improvised at the hardware store or a dollar store.

For a yeast alternative, wouldn’t putting in some bread be a working alternative? Also out of curiosity, has anyone used this to be able to notice an actual decrease in mosquitos? I would like to know if say you put out like 10 of these bottles and fill them up, would that even put a dent in the mosquito population so hopefully you could go outside and not get bit by mosquitos or is this only a very short term help?
That is so cool. I hate them skeeters. I’m going to try to make some and give my feedback to ????? (a.k.a. Cation - cation@ms46.url.com.tw). I saw that their science project had won at least one reward (from Taipei). I’m going to suggest to my daughter’s science club to give it a try, too.

mix dough: flour plus water with a little boric acid and onions chopped into small bits and lard if you have it.
