Clothes moths thrive on undisturbed natural fibers, and a lot of local houses have plenty. Old homes in Goshen, Warwick and the estate homes around Tuxedo Park often hold heirloom rugs, wool blankets in cedar chests, vintage coats in back closets and furniture with horsehair or wool stuffing. Storage that sits for years untouched is exactly what the larvae need.
Seasonal homes are another common source. Lake houses around Greenwood Lake and summer places up the Delaware are often closed for months with wool blankets, rugs and stored winter clothes left behind. Owners come back in spring to find webbing on the bed covers.
Then there is life in the country. Farmhouses throughout the Warwick Valley and Black Dirt region and northern Orange often have wool riding gear, felt saddle pads, mounted hunting trophies, feather beds and hand-knit items around, plus birds or rodents nesting in the attic. Old nests, feathers and pet hair can sustain clothes moths too, so a moth problem sometimes points to a bird nest in a vent or rodents in the walls.
Clothes moths also like dark, warm, still spaces and soiled fabric. A sweater worn once and put away with a little sweat or food on it is much more attractive than a clean one, which is why stored items are hit harder than things in regular use.
