Garlic Mosquito Barriers

Historically, garlic has been used to get rid of many pests, both real and fictional, ranging from slugs to vampires. In particular garlic has a reputation for protecting people from mosquito bites (some think that this could be the origin of the belief that vampires are scared of garlic). There are a number of commercial garlic sprays on the market that can coat an area and produce a natural mosquito barrier. Garlic is allegedly more effective at repelling some species of mosquito than others (although its overall effectiveness is questionable to begin with).
