Sugaring is a technique used by entomologists to attract moths to a specific location. This allows the moths in a specific area to be identified and recorded. The sugar mixture varies between entomologists and the solution usually contains water and brown sugar and then one or more of stout, molasses and rum in different proportions.

The mixture is painted on vertical surfaces such as walls, trees and posts. Moths will be attracted to the solution and can be examined and identified whilst they feed on the mixture. Not all species of moth will be attracted by sugaring, for example those that do not feed as adults will not be attracted. Other species are more likely to visit a sugared location than be attracted to a more conventional moth trap.
