Leek Moth damage


Welcome to the Leek Moth
Information Center for the United States

Leek moth is a pest of members of the Allium family including onions, garlic, leeks, chives and shallots. The larvae feed on crop foliage, stunting plant growth and compromising the storage life of the crop.

The first discovery of leek moth in the US was in 2009 in a home garden in Plattsburgh, NY (Clinton County). This insect is native to Europe and was first found in North America in 1993 in Ontario, Canada.
