What’s a cookout without a cold one (or two)? There’s always a cooler full to the brim with ice-cold beers at backyard barbeques. A few Heinekens can give you a buzz, but even a single beer can make you a target for mosquitos. Scientists are not exactly sure why mosquitos go for beer drinkers, but they don’t think it has anything to do with the increase in ethanol in the bloodstream or the heightened body temperature caused by beer consumption. Like us humans, mosquitos may just like the taste of a good brew.
