Voted Best Mosquito Trap Ever! Here’s How to Make It

Now  add the brewer’s yeast as well  : you can decide whether to use the whole bar (in this case it is best to dissolve it first in a little warm water), just one gram or the powder version, adding the whole sachet. Try it out and choose the one that suits you best.

At this point, take the top part of the bottle (with the cap removed) and place it inside the other bottle upside down.  Secure the two parts with tape  to prevent the chemical reaction between the ingredients from escaping. Finally, cover the edges with dark cardboard.

Place it wherever you want  and you will see that the fusion of water with sugar and brewer’s yeast will trigger a chemical reaction that generates a lot of carbon dioxide, which mosquitoes love so much.  This will form at the bottom of the bottle  and when mosquitoes try to reach it they will get trapped.
