Dawn Suffocates Insects

Just thought I'd share this here. During a summer camp hosted by a college, one of the science professors shared a cool lesson with us. They showed us how to create a safe wasp killer. As you know, commercial wasp killer are so poisonous.

He diluted about two tablespoons of Dawn dish soap in a cleaner bottle full of water, shook it, and then we waited for the bubbles to clear. He sprayed it on some wasps, and slowly they died. Other soaps worked, but not quite like Dawn. He said the Dawn creates a very strong film which coats the simple breathing holes of insects and they then, unless there's a source of warm running water, die of suffocation.

Perhaps this is why Dawn makes an effective flea bath. It's not the water rinsing them away, it's the Dawn suffocating them. Fleas are an insect.
