Take that mosquitos!- Mosquito trap - Cut the top off a 2 liter bottle. Invert the cone and place it inside the straight part of the bottle. Glue the two pieces together. Add 1 tsp yeast and 1/2 cup sugar to some luke warm water, and pour the mixture into the bottle. Mosquitoes are attracted to the carbon dioxide that you exhale. The yeast feeds off the sugar and emits the same gas, so the mosquito enters the bottle, thinking she will find food there.
To get rid of ants, put small piles of cornmeal where you see ants. They eat it or take it home to the others. They can’t digest it so it kills them. It may take a week or so, especially if it rains, but it works and you don’t have the worry about pets or small children being harmed!
