When brewing beer, making wine or growing yeast for a scientific experiment, the pleasant earthy waft of fermentation byproducts usually attracts unwanted guests such as flies and fruit flies. Fermentation byproducts include a range of esters and sugars that are food for insects. More of a nuisance than a problem, an efficient way to deal with such pests is with simple traps rather than resorting to chemical warfare.
