Rugs & Moth Damage: What to Look For
Flying moths do not eat at rugs but just one female moth can lay hundreds of eggs – these eggs hatch into larvae and these pests consume the wool and silk fibers of your rug.
Moths and their larvae thrive in darkened and undisturbed areas where a rug gets very little traffic and is not often cleaned. An infestation often involves more than one rug and can spread from woolen fabrics and furs in closets or drawers. A bad infestation sometimes leaves a cobweb-like covering in the damaged area, along with fine, granular remains – this damage isn’t difficult to repair but reweaving a large area of the rug can be quite costly.
Bare Spots in the Pile
Interestingly enough, Generally moth larvae will prefer the taste of one yarn color over another, therefore the bare spots may involve specific colors being eaten away.
This damage is due to the larvae having chewed through yarn overcastings or bindings.
Long, lightly fuzzy cylinders that are often the same color as the rug’s pile due to larvae’s habit of camouflaging their cocoons to blend in with the colors of the wool that surrounds them.
Larvae in Pile
White, slender, worm-like larvae can often be seen just after hatching, before they’ve built their cocoons, and they are responsible for eating at the wool.
These particles can be found down in the pile of the rug and has a tan or brown color. They have a granular look, are regular in size, and is the excretion of the larvae.
