On your website, someone posted how to get rid of mosquitoes using a plastic bottle. Wonderful idea, but even better, adding vinegar and sugar water will not just get rid of mosquitoes, but pesky annoying gnats too.
Bachelors are too lazy to make syrup (what is....what kind of yeast?:). Pepsi or Coke seems to work fairly well just add a cup or 2 and yes people, the jug design seems to work very good but you don't even need to go through that trouble either. Pepsi or Coke has so much sugar it turns sticky and they become stuck or unable to fly at all once they get that gook on -em gl :)
