<\/p>\nWool tweed in storage is a food source, and something knows it. Webbing clothes moths and carpet beetles lay eggs in dark, undisturbed fabric, and their larvae eat keratin, the protein that makes wool wool. A brand that stores off-season boucle and tweed rolls in an unconditioned warehouse can lose selvedges, bare patches and whole meters to larvae that never touch synthetic fabric on the neighboring shelf. Prevention is cheap and entirely mechanical; the expensive part is discovering the damage at cutting time.<\/p>\n
Our partner mills in Wenzhou keep wool and wool-blend inventory, including the 100-meter stock lots that ship with no minimum, in conditioned storage year-round, and storage discipline is part of what buyers audit when they visit. This guide covers what actually causes moth damage in fabric storage, the prevention stack that works, and how to write storage requirements into a fabric program so damage risk does not silently transfer to whoever holds the goods.<\/p>\n
<\/p>\n
Adult moths do not feed on fabric; they only lay eggs. Damage comes from larvae, which need keratin, the protein in wool, cashmere and other animal fibers, and they favor fabric that carries traces of food, sweat or starch. That is why stored garment samples and soiled swatches are hit first, and why clean, tightly wrapped fabric is a poor habitat. Larvae also avoid light and disturbance, which makes rarely-opened stock rooms the ideal nursery. Synthetic and purely cellulosic fibers contain no keratin and are largely ignored unless blended with wool.<\/p>\n
Buyers verifying pest-control approaches in a supply chain will find that consumer pesticide guidance, such as the resources maintained by the National Pesticide Information Center<\/a>, covers the safe use of mothball-type repellents, and the same cautions apply to warehouse-scale application: chemical repellents are a supplement to, never a replacement for, clean and sealed storage.<\/p>\n First, clean before storage: brushed, aired and inspected fabric carries fewer attractants. Second, seal: poly bags or sealed film per roll deny adults access to the laying surface, and this single measure prevents more damage than any repellent. Third, climate: moderate humidity and temperature, regular airing and inspection every few weeks, because light and movement break the egg-to-larva cycle. Fourth, monitoring: pheromone traps for webbing clothes moths show an infestation while it is still one moth, not one bald roll. Fifth, only then, repellents, used sparingly and never in direct contact with fabric.<\/p>\n These measures also protect fabric quality more broadly: the same conditioning that suppresses moths protects yarn hand and color, the concerns covered in our yarn storage and conditioning guide<\/a>. And for buyers who minimize warehousing risk altogether, the alternative is not holding inventory: stock programs that ship on order, like the reorder pattern in our 3-week stock reorder case study<\/a>, keep rolls in the mill’s conditioned storage instead of a brand’s unconditioned one.<\/p>\n Storage responsibility should be explicit in the order terms: who conditions the space, who inspects, and what happens when damage is found at cutting. For goods held before shipment, our storage is part of the program: wool-blend tweed from our tweed fabric collection<\/a> is bagged and conditioned between finishing and dispatch. On the buyer side, spec the same discipline: sealed bags, inspected stock rooms, no fabric stored loose on open shelving. Before ordering, check how fabric is presented and packed using the approach in our swatch checklist<\/a>, because a mill that swatches cleanly usually stores cleanly.<\/p>\nThe prevention stack, in order of effectiveness<\/h2>\n

Purely synthetic boucle is largely ignored, which is one reason blends store more safely than 100 percent wool.<\/p>\n Are mothballs the best prevention?<\/strong><\/p>\n No. Sealed storage is more effective and carries none of the handling precautions of chemical repellents. Repellents are a supplement, and safe-use guidance is available from resources like the National Pesticide Information Center.<\/p>\n How often should stored fabric be inspected?<\/strong><\/p>\n Every few weeks in unconditioned rooms, with airing and a light check of bag integrity. Conditioned, sealed stock can be checked monthly. Pheromone traps shorten detection to days.<\/p>\n Who is responsible if damage is found at cutting?<\/strong><\/p>\n Whatever the order terms say, which is why storage responsibility, inspection cadence and damage handling should be written into the program before goods transfer, not argued after.<\/p>\n<\/div>\n |
