In our line of work we see a lot of carpets. Recently we’ve also come across quite a bit of carpet moth damage.

Carpet moths are tiny. But don’t let their size fool you, they are also incredibly destructive.

Their larvae are the main culprit for any damage. They feed predominantly on keratin which is found in natural materials like wool, cotton and silk, so your carpets make for a tasty snack! All the larvae do is eat, so they can get through a lot of carpet, despite their tiny size.

Carpet Moth LarvaeHow do you spot them?

There are a few tell-tale signs which will give away whether you have a carpet moth problem. The first and most obvious being bald patches on your carpet, especially in hidden and unused areas.


The larvae can be really tricky to spot. They digest the dye in the fibres so are often the same colour as your carpet. As they keep munching away, however, they will weave a silken case around themselves. These cases look like grains of rice so are a little easier to spot.

Once the case is large enough the larvae will seal itself in and pupates into an adult moth.


Carpet MothAdult carpet moths are only small. Their bodies are just 5mm long and the wingspan is usually 14-18mm. You can also identify a carpet moth by their

colouring. They are a light brown colour with three dots on their wings. They don’t fly very often so you are more likely to see them hopping around.

The adult moths live for just a few months and are not prone to eating the carpets. But they can lay anywhere between 30 and 300 eggs in their short lifetime! These eggs turn into larvae which, as we have already discovered, will eat your carpet so you don’t exactly want the moths hanging around.

What conditions do they like?

The heat and humidity of a room will affect the lifecycle of the month. If they are in a warm and humid environment the larvae could develop into an adult moth in as little as two months. When it is cooler and less humid it could take up to two years.

The most typical places you are likely to find larvae are:

  • Under sofas
  • Behind heavy curtains
  • Along skirting boards
  • Beneath heavy, rarely moved furniture.

Tips on getting rid of carpet moths and their larvae.

As soon as you spot signs of damage on your carpets, it’s time to take action! If you don’t, you will be left with a rather bare and unattractive carpet. Replacing a carpet will cost far more than treating the problem.

Keeping your home clean is the key to avoiding moths. A good regular clean takes away the opportunity for their larvae to thrive.

Regular vacuuming is an excellent place to start. Don’t neglect under the furniture. Moth larvae thrive in undisturbed spots.

But what is even better than a vacuum? A deep carpet clean, of course! The cleaning solutions will get right down into the carpet fibres removing even the most well-hidden bugs. Here at Resolve Carpet Care we have our very own cleaning solution that will do just the trick. It has a built in sanitiser and deodouriser so, not only will you carpets be super clean, they will also smell nice and fresh.

If you are unfortunate enough to spot an infestation there are plenty of treatments out there you can buy. These tend to come in powders and sprays which you apply to your carpet to get rid of the larvae and traps for catching the adult moths. If you have a particularly bad infestation it’s always wise to call in pest control instead.

If we identify any carpet moth whilst we are cleaning, we will make you aware and even leave a free moth trap.
