Step 1: Find Where They Actually Are

Larvae avoid light and disturbance. That is the entire search strategy: go wherever nobody goes.

• Move heavy furniture. Under the sofa, behind the wardrobe, beneath the chest of drawers — anything static for a year
• Lift the carpet edge along the skirting with a flat tool and look at the base of the pile
• Check the corners, especially behind a door that stands permanently open
• Lift rugs and check both the rug and the floor under it
• Check stair treads at the back where the tread meets the riser
• Look under long curtains where they rest on the carpet
• Check wardrobes — wool jumpers stored unworn are frequently the original source

You are looking for gritty debris, silken webbing, small cream larvae, and thinning pile. Debris comes before visible bare patches, so it is the more useful early sign.

Step 2: Vacuum Properly, and Keep Doing It

With carpet moths, vacuuming is genuinely a large part of the answer — larvae, eggs and debris are physically removable in a way most pests are not.

• Crevice tool along every skirting and in every corner, slowly
• Vacuum under furniture, not around it
• Stair treads properly, into the angle at the back of each one
• Both sides of any rug, and the floor beneath
• Repeat every few days for several weeks — one pass is not enough
• Empty into a sealed bag and put it outside immediately, or you have relocated the infestation to your cupboard

Step 3: Deal With Textiles and Stored Items

• Hot wash anything washable — heat kills all stages
• Freeze what cannot be washed. A sealed bag in a domestic freezer for a couple of weeks works for smaller wool items
• Dry clean anything valuable that takes neither
• Store cleaned wool in sealed containers, not open wardrobes — moths lay on soiled fibre by preference
• Clean before storing. Sweat, food residue and body oils on wool are a strong attractant

What Does Not Work

• Pheromone moth traps. They catch adult males and are genuinely useful for monitoring. They do not control an infestation, and sold as a solution they are misleading.
• Lavender, cedar and mothballs. Traditional, pleasant, unreliable against an established infestation.
• Swatting the adults. Satisfying, irrelevant.
• Supermarket sprays alone. Surface treatment. The larvae are at the base of the pile and in the underlay.
• Shampooing the carpet. Cleans it, does not remove larvae, and adds moisture.

Step 4: Professional Treatment

What treatment adds is penetration and persistence: reaching the base of the pile, the carpet edges and beneath furniture where the larvae are, and remaining active as further eggs hatch.

That persistence is why one-off sprays disappoint. Eggs already laid hatch over the following weeks regardless of what you did today.

Afterwards

• Keep vacuuming — it is the maintenance that prevents recurrence
• Move furniture periodically rather than leaving it for years
• Use pheromone traps now, as monitoring — catching adults tells you it is not finished
• Store wool clean and sealed
• Check the undisturbed spots twice a year — it takes ten minutes

Is It Definitely Moths?

Carpet beetle larvae do very similar damage. Moth larvae are smooth, cream, often with silk webbing or a small portable case. Beetle larvae are brown, visibly bristly, and leave shed skins that look like more larvae.

Questions People Ask

Will they eat synthetic carpet?

No. They need keratin from natural animal fibres.

Do I need to replace the carpet?

Not for pest reasons. Whether damaged carpet is worth keeping is a decision about how it looks.

How long does it take?

Expect a process rather than a moment, because eggs already laid continue hatching. Ask us what to expect.
