FAQs

No—exterminators treat spaces, but rug moth proofing treats the textile fibers. Room sprays may reduce adults, but they often don’t reach eggs/larvae inside the rug.

Plan on re-treatment about every 3–5 years in typical homes. High-risk conditions (dark rooms, storage, prior infestation) may justify a shorter cycle.

It works best after professional cleaning because soil and oils make rugs more attractive and can reduce treatment performance. Clean fibers hold protective finishes more evenly.

Damage can become significant before you notice it because larvae feed beneath the pile. A single female can lay roughly 100–150 eggs, so problems can multiply quickly.

Check the back of the rug, edges, fringe, and the areas under sofas and along walls. Moths often start in low-disturbance zones only a few inches wide.

Look for small bare patches, “sand-like” frass at the base, silky webbing/tubes, or thinning along edges and under furniture. If you see these, activity may already be underway.

Rug moth proofing is most relevant for wool, silk, cashmere, and other animal-hair fibers. It’s less relevant for 100% cotton or synthetic rugs because larvae don’t feed on those.

Most textile damage is caused by webbing clothes moths and casemaking clothes moths. Both target animal-based fibers and prefer dark, undisturbed areas.

Larvae do the damage, not the adult moths. Adults mainly mate and lay eggs, while larvae feed on keratin in wool and silk.

Rug moth proofing is a fiber-safe treatment that makes wool and other animal fibers unattractive to clothes moth larvae. Done correctly, it adds a protective “shield” that typically lasts about 3–5 years.
