Cut the top off a two litre bottle. Invert cone and place it inside the straight part of the bottle. Glue the two pieces together. Add one teaspoon of yeast and 1/2 cup of sugar to some lukewarm water. Pour the mixture into the bottle. Mosquitoes are attracted to the carbon dioxide that you exhale. The yeast feeds off the sugarand emits the same gas. So, the mosquitoes enter the bottle thinking she will find food there.
found this on fb...thought I should pass it along.
