Introduction: How to Make a DIY Mosquito Trap

Picture of How to Make a DIY Mosquito Trap

I hate mosquitos they are buzzing and biting. We have to fight but the weapons are limited...
You can use chemicals, candles, insecticides, nets etc. They effectiveness are not enought in every situation but here is another solution to stand well in the fight against these bastards :)

If you want to learn about the enemy read these Mosquito facts:

- Mosquito is Spanish for “little fly”

- There are more than 3,500 species of mosquitoes

- Only female mosquitoes bite people - Mosquitoes don't have teeth

- A mosquito can drink up to three times its weight in blood

- Female mosquitoes can lay up to 300 eggs at a time

- Mosquitoes spend their first 10 days in water

- Mosquitoes hibernate - The average mosquito lifespan is less than two months

some more on the link ;) (from:

Step 1: Watch the Video!

It only take 10 minutes to make one!

Step 2:

Picture of

As you can see on the picture the tools and ingredients are:

  • a soda bottle (any size usable but bigger is always better)
  • yeast
  • sugar
  • lukewarm water
  • knife (or a scissors)
  • any kind of adhesive tape

Step 3: #1

Picture of #1

Take the knife and carefully cut the top third of the soda bottle!


Step 4: #2

Picture of #2

When the cutting is done push back the top inversely into the bottle.

Don't forget to take off the cap ;)

Step 5: #3

Picture of #3

You can skip this step if the top stay tight in the bottle.

But if it's not just take some tape stuck together the two parts.

Step 6: #4

Picture of #4

Here comes the soul of the trap! The mixture!!!

Put the yeast the sugar and the lukewarm water into the bottle trap.

Mix it well.

The mixture emits carbon dioxide which attract mosquitoes. They thinks it's food in the bottle and once they flew in they couldn't get out anymore!

Step 7: #5

Picture of #5

You can place it where ever you want inside-outside near or far. Try to put it next to the most infected areas.

Step 8: The End

This trap is also effective against flies, bugs etc. So it's a must try project!

I put it out to the terrace! I hope it's as effective as it mentiod everywhere!

I will try to make some picture and update this instructable with my results.

If you like this projekt just do it and give my feedback about your results!

Thanks for reading this article!

That's the ShiftyWay ;)

I made one of these once and it didn't work at all, not a single one flew in and the thing started smelling awful after a couple of days and had to throw it away

BrunoM196 (author)2017-04-02

Does it really work?

cranakis (author)2015-07-20

I wish this worked. The Mosquitos are thick where I live so I made a few last summer and set them in an area where I get bitten constantly. I don't think a single mosquito went in after a full day. While I was checking the trap I got bitten 3 times. Maybe I have a different breed of mosquito around here but this is ineffective in GA.

jseth (author)cranakis2015-07-27

these traps would only catch males and not females. females are the only ones who bite and drink blood

hamzamasoud (author)jseth2015-08-05

So, what is the point of all this hassle?!

spanish lessons

MarcS1 (author)2015-07-15

Mosquito is a Spanish word and means mosquito.

Fly in Spanish is mosca.

When I was child we made this traps in school but whit fruit, to trap flys.

harmonious1 (author)MarcS12015-10-02

The literal translation is "little fly", mosca = fly, ito = little.

MarcS1 (author)harmonious12015-10-10

Litte fly is translated "mosquita" because "mosca" is a feminine word. Castilian has gender.

From the royal spanish academy of the language:

leon-geyer (author)MarcS12016-02-22

Yes, but the same dictionary says "Del dim. de mosco." just on the page your refer to. DIM = diminutivo = diminutive = characteristic of little

I think ShiftyTips is talking of etymology, there is a word mosco, and latin musca, so yes, it comes from "little fly" more or less, so he is right. At the other hand, MarcS1, you are right in saying to bhagan1 there is a word in spanish for them = it is mosquito. It is specific and not used for other insects, like real little flies. To bhagan1: there are other coloquial spanish words too, like Zancudo, and the scientific ones.

En fin, está bien que seas detalloso y exacto, pero el lenguaje no solo tiene un ahora, tiene un devenir y áreas imprecisas (¿acaso hay una diferencia exacta entre mosco y mosca en todas sus acepciones?), por ello en el sentido de de donde viene el término, el autor tiene razón. por cierto : vaya off topic :)

Thank you for the instructable, I am trying it right now. A similar one, with pictures instead of video and some more detail in measures (and other stuff, like saying why you have to tape around), is

best greetings

bhagan1 (author)MarcS12015-07-15

In a manner of speaking, there is no word for mosquito in Spanish as they simply call them "little flys".

MarcS1 (author)bhagan12015-07-16

I'm Spanish. We call them mosquitos. And the link explains it clear. English adopted the word in 1580s, from the Spanish word mosquito.

tmiller1958 (author)MarcS12016-01-17

meh, mosquito sounds spanish to me, here in these parts some callem, miskeeters, others just plain skeeters.

oözbay made it! (author)2015-07-30

ı'm trying

LaysDIY (author)2015-07-15

First of all i'm sad about your negative experiences...

A really hoped it works. Maybe the trap idea is not bad just have to figure out a mixture which attracts the mosquitoes better.

We have a very windy and rainy weather here so can't really test out the trap because the mosquitoes are gone...

I try to search for a new recipe and if i have a new a mixture i will share it with you.

Thanks for all of you ;)

MarcS1 (author)LaysDIY2015-07-15

Try putting a russian dwarf hamster with a protection metal screen of course :)

bhagan1 (author)MarcS12015-07-15

Wait, you never tested this? Why would you post it if you haven't tested it to make sure it works? Or at least asked someone else to test it for you first?

His Tips are Shifty?

does this work on bees, wasps and midges as were i live is thick

MunchkinT (author)daisy4512015-07-25


Jackie mabbott (author)2015-07-21

thats very clever, I will make them today. Thanks for sharing your idea.

notforfooduse (author)2015-07-20

For those wondering whether this works, we've been making these for years to dent the wasp population near us and they're pretty effective–so much so that it's sometimes quite sickening seeing the huge mass of dead wasps trapped inside. We use old jam or sugar dissolved in water as bait to catch the wasps and hang the traps as close to their nests as possible. The wasps enter through the neck, eat some of the jam and then try to crawl up the inside of the bottle to leave only to be blocked by the inverted top of the bottle. I can't say how well this would work with mosquitoes though, since they're a lot smaller and more likely to be able to escape back out through the neck.

acoleman3 (author)2015-07-14

female mozzies find their victims by the carbon dioxide they give off, which is produced by the reaction of the yeast. even commercial units use co2 as bait. maybe you should do your research better.

steelshado (author)acoleman32015-07-15

Commercial units use multiple attractant/bait types, not CO2 by itself; maybe someone else should research better before they call someone out. This bait model has been shown to be ineffective, even with the yeast CO2 reaction.

Lots of people use this, but do so with yeast-based liquids (kombucha, kefir, etc).

It's not ineffective, no matter how many times you say it is.

DIY Mosquito Trap

What kind of yeast , Brewers of Nutritional? How much of each ingredient?


WawanH (author)ingveig2015-07-20

i think everything that make CO2 from sugar

perfo (author)2015-07-16

UV kills yeast so cover the bottle to make the reaction last longer. I too have built a few of these and tested them in mossy infected areas and whilst i did catch few mozzys 99% of them ignored it or stayed away from it..

C02 is used to track mammals from afar but infra red and pheromone take over as the mossy gets closer to the prey. As they are mainly designed to attack things like cattle maybe a bulb painted black and some grass pheromone would be more effective??

wilsondm (author)2015-07-15

gostei desta armadilha vou tentar,o inseto ruim e barulhento e chato

itsmescotty (author)2015-07-15

I would happily put 500cc of MY blood in a trap if they would just quit biting and annoying me.

steelshado (author)2015-07-15

Kudos on the build instruction; I've not yet had success with this model, but apparently adding an Octenol tablet to the mix boosts effectiveness. I haven't tried it myself yet, but let us know if ya give it a shot. Rock on.

alba100 (author)2015-07-15

I have made these types of traps for a number of years, and found them great for catching flies, and when I get enough flies, I simply bin the trap and make another, but despite many attempts have not made a bait that attracts more than the occasional mosquito. So I am looking forward to some good suggestions re bait.

It is winter here in Australia, so mosquitos are not a problem. My experiments will restart in 3-4 months time.

paqrat (author)2015-07-15

A couple of suggestions you might try to kill off the critters that fly into the trap quickly. A drop or two of dishwasher detergent should lower the surface tension of the water so they will sink like little stones. If you don't want use the detergent then I'd try putting a cover on the top of trap then placing the whole thing in the freezer. I'd guess an hour would be all it would take to freeze all the critters. I think after thawing out the yeast should commence again.

Misterking03 (author)2015-07-15

100 g of sugar ?

fixfireleo (author)2015-07-14

man, if only you could adapt this design to work on POLITICIANS!!

JeffN4 (author)fixfireleo2015-07-15

You can. Just substitute the liquid for money. What politician can resist easy money?

who1buffy (author)fixfireleo2015-07-14

LOL !!!

rcpilotacro (author)2015-07-14

Apple cider vinegar and baking soda works better (On at least the mosquitoes in my area) :)

HennieW (author)2015-07-14

A bat house is a much better idea.

ssharma39 (author)2015-07-14

No it does not works. It needs something more to produce little heat to attract mosquitoes.

nraj singh (author)2015-07-14

mosquitoes need heat as well so try something which undergoes exothermic reaction releasing co2 also .

tlebsack (author)2015-07-14

I have made several of these over the last few months. Common house flies caught - hundreds. Mosquitoes caught - ZERO. The CO2 as attractant theory sounds plausible but we're missing something. My experience is that they do not work as described. Looking forward to the Instructable that shows a picture of the mosquitoes in the trap.

nraj singh (author)tlebsack2015-07-14

mosquitoes aren't just attracted to co2 they need heat as well so any reaction which is exothermic and emits co2 is a good substitute

iceng (author)2015-07-14

Mosquito lay eggs in stagnant water.

stanperry01 (author)2015-07-14

Mosquitoes dont like yeast, maybe try vinegar and baking soda for co2

mushtaqdhari (author)2015-07-14

super cool ideas.

Hollyhd-Hamadac4 (author)2015-07-14

It looks intriguing

estevens12 (author)2015-07-14

I have read that these don't work because mosquitoes dislike yeast? However the same principle will work as a wasp trap if you use a sugary drink as bait.
