For those unfortunate enough to feature highly on the mosquito hit list, summer nights are synonymous with mosquito bites. Yet others hardly ever get bitten. So how do the blood thirsty insects select their victims?

The insects' tastes may seem arbitrary. However, research reveals that when mosquitoes make their choice between potential victims, it all comes down to scent:

Mosquitoes are attracted by carbon dioxide and heat, which everyone gives off. But mosquitoes are also attracted by certain scientist, Karl-Martin Vagn Jensen.

The scents of the lab employees were deposited on the dishes, which were then put in an enclosure full of mosquitoes. The mosquitoes repeatedly landed on some of the Petri dishes, but didn't go anywhere near the others. According to Jensen, it has not yet been established exactly what the scents in question are. But research does indicate that some scents are more attractive to mosquitoes than others.

There are also those who swear by garlic as an excellent repellent against the winged bloodsuckers. According to the researcher, though unsubstantiated, this strategy may not be entirely fruitless. "As far as I know, there is no scientific proof that eating garlic works. But there may be something to the theory that it's possible to mask your scent with garlic,"he says. The only reliable method of protection against mosquitoes is to use one of the effective repellents that are sold over the counter.
