Want to make a homemade mosquito trap? Why not, with a few cents investment you may be saving yourself or your family from a terrible disease. People think of mosquitoes as feeding on blood. Actually only the female mosquitoes need a blood meal for her eggs. Otherwise, mosquitoes are feeding on sugary nectar in your flowers and the flowers on trees and shrubs. We are going to take advantage of those feeding preferences when we make our traps. Mosquitoes are also drawn to dark places so we will use black paper to make a dark place.
Save a 2-liter pop bottle and rinse it out. Set aside the cap. Now, this is where recipes differ. It really doesn’t matter what kind of sugar and the exact proportions. You need water, sugar, and yeast. The yeast will eat the sugar source and create CO2. Mosquitoes are attracted to CO2, they go in the cone and down into the solution and can’t get out. If you are alright with dirtying up a pan, put in a cup of water and when it is boiling, add a cup of white sugar and stir until it is dissolved. Then when it has cooled off some, add 2 more cups of water and 1 tsp. of yeast. Mix and put in to the bottom of the 2 liter bottom. Invert the top that has been cut off and set inside the bottom. Seal the two parts of the bottle with tape. Cover the bottle with black paper. Other recipes include 1 cup of water with 1/3 cup of brown sugar and yeast. If you are out of white sugar or brown sugar you can use another source of sugar like orange juice.
Yeast will live in a wide range of temperature. It goes dormant below about 65-70F and die off above about 130-140F . Yeast is the most active in the 85F-95F range so it should work great for this mosquito trap most of the year.
If you don’t want to wash a pan, add very hot water to the sugar in the bottom of the bottle. Add the yeast to the sugar mixture in the bottle also. Change the solution every 2 weeks. Another variation to the recipe is to add 1 TB of vinegar. Adding the vinegar is said to attract gnats, killing two birds with one stone. You can also add ½ tsp of Boric acid so that if the mosquitoes did manage to escape they would die from ingesting the boric acid. Also it kills the mosquitoes quicker.

Once you make your homemade mosquito traps, now you have to know where to put them. First, you can hang them if you have plant hangers on your patio. See the picture on this post. If you aren’t going to hang them, don’t put them too near your outdoor seating areas. The whole point is that they attract mosquitoes, so we don’t want them buzzing you and trying to decide if they would rather bite you or go to the solution. Keep them on the perimeters, like 30 feet out from where you will be. Put them upwind so they smell the solution first. Seems self-evident, but people who complain about traps not working usually have them too close to their areas. Keep the traps out of the sun for best results.
One of the great things about these mosquito traps, besides them working and saving money, is that you aren’t spraying chemicals in your lawn that will kill butterflies and bees. This is a cheap, fast, natural control method.
If you don’t like the bottle mosquito trap, you can use some tapered bottles and drop some dry ice in each of these. The dry ice will create CO2 and attract mosquitoes for a couple of hours.
As you can see, making a homemade mosquito trap is cheap and easy. Please leave us a comment and let us know how your trap ended up and if it works for you. Let us know if you changed the recipe or tried any of the variations.
