Hello dear friends!

As some of my followers already know, I live in Bologna (Italy), in the heart of Po river Valley.

This area is known as the wettest one of Italy. This is due to terrain, level (a lot of areas are UNDER sea level) and weather.

These factors result in very hot temperatures in summer, very cold ones in winter, an incredibly thick fog but, mostly, giant and aggressive mosquitoes.

There is a city, Comacchio (only 55 miles from Bologna), that is known as the "Mosquitoes Town". XD

Obviously is nothing tropical, but it's very annoying!

It's really difficult to enjoy summer evenings without using pesticides, sprays or other stinky poisons. Or, you can always avoid using anything and... be eaten alive by these little vampires.

While mosquitoes are useful for the ecosystem (did you know that mosquitoes are the main cocoa plants pollinators? No mosquitoes means no chocolate!!!), we don't want them to fly around our garden and bite everything that's alive, pets included.

In this Instructable, I want to show you an all natural and potentially free way to create an efficent mosquito trap with little more than a plastic bottle!

Why potentially free? Because we will use materials that are always present in our home!


Let's start with our shopping list.

Thanks for the bottle trap instructable.

May I ask the source of your information regarding mosquitoes being a pollinator of cacao flowers? Have you ever observed mosquitoes on cacao? I have been told by certain researchers that it may very well be physically impossible for mosquitoes to act as pollinators given the size of the cacao flower and the anatomy of the stamen, but I am willing to give you the benefit of the doubt, if you can provide scientific evidence of this.

Hi friend! :) No, I've never seen mosquitoes on cacao with my own eyes, but I've read it in a "Le Scienze" (italian version of Scientific American) article years ago.

You can find a lot of similar articles on various scientific websites!

Here's an example :)

Have a super day!

It also works Indoors to catch Flys. I am still however, working on a trap like this for ants.

Will this also attract mosquito from the neighbor's gardens?

mmm, don't think so, it's not enough powerful

Congrats on making finalist! Can't believe the view count! Wow. I need to try this method. Am sharing with hubby so he can make one. Thanks for sharing and keep shining.

Although the camping trip didn't happen, I did make this trap. I set it out indoors for some time (although I don't have a mosquito problem indoors, in general) and it didn't catch anything. Then I put it out overnight near the garage: it has been quite damp, and mosquitoes frequent the area. Today I emptied the contents onto a paper towel to see what was caught. Alas, it was just a couple flies. The odor was very yeast-like, and I wonder if that contributed to the mosquitoes avoiding it. Has anyone had a proven success?

I'm trying to think if we have bottles with this style (the grip part) in the US. The easiest 2 liter bottles to get a hold of is soda bottles, which (around here) are straight up and down.

Darthorso (author)  adillbeck8 months ago

I've travelled in the US a lot of years ago, and I remember to drank from a bottle like this... if you can't find this kind, simply help yourself with some extra tape! :)

Propel bottles might do.

Try maybe water or juice bottles.

I understand how the tape holds the upside-down top you cut off the bottle in place inside the larger portion of plastic bottle as a funnel to confuse any attempted escaping mosquitoes. I see tape around the top of the Baileys can. For the life of me, I can't understand why that is there. Is the Baileys can sharp there and you are protecting yourself from it? Does the tape help keep the plastic bottle in place inside the Baileys can? For what reason does it exist?

Oh, never mind. I see now that the plastic bottle doesn't fit fully inside the Baileys can as the tape makes it too large to slide down all the way.

I also just noticed that the top part that you cut off is inverted when you tape it back and I don't think that was mentioned on the instructions and if you did I missed it. Is that why you use the tape? .Thanks anyways. AL.

Darthorso (author)  alsports20008 months ago

I mentioned in step 3: "Now that the mixture is ready, put the top part of the bottle inside the big one, face down, to create a funnel (the picture shows it well)."

It's used to make the funnel effect :) Also, we use black tape for 2 reasons: hold evrything in place and seal the bottle to avoid too much CO2 to go away ^_^

In addition to which I just read that skeets are particularly attracted to black, navy and red so the bailey's red is right on for an added attractant; however I also read that bats are NOT that interested in skeets as a first choice, they prefer other insects. Right now after wearing 2 layers in my gardening, I have 16 very itchy bites on my upper arm, shoulders and hands. They bite right through 2 layers, with lots of herbal spray and a net hat with veil over face. North Central FL has been raining for weeks and they are the worst ever. I tried this with chopped meat in it for yellow flies who are way worse than skeets and the rain kept filling up the jug and not one fly. So I gave up but will try again. I think someone here gave an ible for herbal mosquito spray with witch hazel and several essential oils. About to make that. Very frustrating.

For the bites you did receive, toothache pain reliever like orajel works to stop the itch and it does not return. I have also read that a warm metal spoon will relieve the itch and stop the reaction from the bite, however, I have not tried that method.

Best mosquito bite remedy... Hairdryer treatment. This works EVERYTIME. I am one of those people that gets bit when no-one else is, so I know this works. Take a hairdryer and blow the hot air on the bite/s for as long as you can stand it w/o burning yourself. That's it! The hot air destroys the proteins that cause the redness, swelling and itching. My bites disappear and never get itchy anymore :)

This same type of trap is great at ridding an area of fruit flies. The only difference is the mixture in the bottle is substituted with red wine! Fruit flies in, drink, and become too drunk to find their way back out. They eventually drown...

Darthorso (author)  HerNation7 months ago

Wow! Red wine? Cool! I'll try that!

Thanks! :D

You could use distilled water instead of boiled tap water.

Years ago I read that the mosquitoes were attracted to warmth (like body temperature) + humidity. Perhaps that is why they seem to whine around ears. (would I notice them if they were whining anywhere else ?) Adding yeast for CO2 makes sense. Thanks for posting!

I once purchased an excellent "Fly Trap". It worked so well not one of my neighbors had a single fly! They were all at my house. Needless to say it wasn't the perfect solution. Good luck and beware the West Nile virus.


SnazzyBot made it!7 months ago

I used baker's yeast because I had it on hand. I set it outside for a couple of days, and I caught a bunch of flies! :O

Looks like a good idea and well executed. Have you tried adding just a little dish washing detergent to the water? I don't know if it would affect the attraction but if it didn't harm the c02 production it would certainly help in killing the mosquitos. The detergent lowers the surface tension of the water and theoretically the mosquitos should sink in the water like stones. I have made several successful flea traps using just a small open container (currently using clean cat food cans) . I fill the can about half full and add a drop or two of dishwashing detergeant. The fleas apparently are attracted to the scent of water and they willingly throw themselves into the can where they sink.

PhilKE3FL paqrat7 months ago

You know, mosquitos breed in stagnant water, I wonder if using this same trick on a home-made stagnant water pool would do the same for mosquitos?

I've used this trick to reduce the water tension for drowning all sorts of bug pests. Never thought of it this way for some reason.
