Does garlic really work against mosquitoes?

Given how quickly those pesky insects seem to adapt and become immune to various bug dopes, we can’t say for sure, but it’s worth a try. Some people swallow slivered garlic to ward off these summer pests. Others take garlic tablets or rub garlic juice directly on their skin. If you do get bitten or stung, a paste of mashed garlic can help take the sting and itch away. Some people apply garlic, onion, or radish juice for the same purpose.
