Back to the mosquito problem... I hadn't thought about them much this year, until I went hiking a couple of weekends ago in the Holy Cross Wilderness. The swarm that greeted me there reminded me of a local outdoors guy who has called a few times over the years. He swears he knows how to keep the mosquitoes off you - by eating garlic.
He's not alone - check out "garlic" and "mosquitoes" on Google, and you'll find tips for spraying yourself and your plants with garlic as a mosquito repellant, as well as popping garlic capsules to ward off the evil pests. No word on whether eating vast quantities of Italian food will help as well, but it wouldn't hurt to try, in the interest of research.
