How can I create a DIY mosquito trap for indoor use?

To create a DIY mosquito trap for indoor use, you can use a plastic bottle, sugar water, and yeast. Cut the top off the bottle, invert it, and place it inside the bottom half. Mix sugar water and yeast in the bottom half to attract and trap mosquitoes. The yeast produces carbon dioxide, which attracts mosquitoes. Place the trap in areas where mosquitoes are present.
