RUG MOTH DAMAGE TREATMENT

When Are Moths Most Active?

Carpet moths, also known as clothes moths or tapestry moths, are not strictly seasonal pests, they can be active year-round. However, their activity does increase during warmer months. This is when the environment is most suitable for their reproduction and growth.

What Do Moths Eat?

Clothes moths (the same ones that eat your rugs) like to diet on anything that contains protein, particularly wool, silk, fur, feathers, felt, leather, animal hairs, and even cotton and synthetic fabrics such as polyester and rayon if they are heavily soiled with food stains or body oils. They are more likely to feed on soiled materials. [1]

These insects may remain at the larval stage (the stage in which they feed) for up to three years, during which time they can do immense damage.

Do Moths Eat Rugs?

Yes. Moths appear to be the true connoisseurs of textiles, consistently gravitating towards rugs of the finest and most expensive varieties. The moths we’re familiar with (Figure A) don’t actually feed on the rugs or even lay eggs, they are the male moths that mate with the female ones (Figure B) who hop and skip around to lay their eggs. In fact, these adult moths only survive for about a week after they hatch from their cocoons. It’s the eggs they lay (anywhere around 100) and the larvae they turn into that feed on rugs for years at a time that do the damage.

What Causes Carpet Moths?

Introducing just one item infested with moths into your home could potentially lead to an infestation affecting all vulnerable items. Older houses with warped doorframes and siding meet the conditions these pests need to flourish, as well.

Other things that are likely to attract these moths into homes include:

  • Places in your home that are rich with natural fibers and are dark & undisturbed like your closets, drawers, or chests.
  • Pet hair or lint around baseboards and corners.
  • Clothes moth eggs can inadvertently be transported into your home on new, but more likely used purchases.

How Can You Tell if You Have Moths In Your Rugs?

Larvae are the worm-like creatures with transluscent bodies. The white specks and black specks are a combination of their eggs and digestive waste, or speaking more coloquially, moth babies and moth poop. (Figure A)

Yeah, gross.

You’ll likely notice their presence once damage has already occurred, where the foundation of the rug is intact while the wool pile has been disfigured, or is gone entirely. (Figure B)

Look into rug moth damage repair services if this is the case.

For rugs that have been laid out, all of this damage is most likely to be hidden under furniture legs, couches, and any other area that doesn’t receive regular light, traffic and vacuuming.

The silk-like webbing that they spin over the fibers they are feeding on is a surefire way of confirming the presence of clothes moths, although it’s difficult to distinguish this from strands of fiber in Moroccan-like rugs. (Figure C) This is why preventative care, outlined below, is so important.

Cleaning Moths From Your Home

Start with Your Closet

  • Moths and larvae love dark cracks, corners and crevices, you’ll want to start in your closet and focus your cleaning efforts here.
  • Discard particularly infested items. Thoroughly clean the ones you keep by either washing them on high temperature, dry cleaning or freezing them for 12 hours. If you find evidence of moths in any of your rugs, such as loose pile, bare patches, spidery webs, cocoons, or live larvae, check all of your rugs since larvae can move from rug to rug.
  • We recommend placing these sticky moth traps from Amazon in your closet. They’re effective at catching adult male moths, known as webbing moths, if for no other reason than to confirm your suspicion of a moth infestation.
    • Set them out in your closet, under your bed, chest of drawers and any other dark spots you suspect moths could be reproducing in. It’s better to go overboard here, though only a few of the traps may catch any moths you’d rather be safe than sorry.
  • Remove the vacuum bag and discard it outside immediately, because it will probably be full of eggs and larvae, which can then crawl back out of the vacuum bag or trash bin and into your home.

Work Your Way In

Regularly and thoroughly clean the home, including vacuuming inside drawers and closets, on and around upholstered furniture, and even along baseboards, identifying the species of moth and addressing the infestation can be confusing.

For peace of mind, it is always best to call in a pest control provider who can assess the situation and implement a plan to address it.

In the case of clothing moths, cleaning the appropriate areas, such as carpet and/or fabric surfaces, is critical for removing larvae.

Make sure to clean underneath difficult-to-reach areas, under furniture, including their legs and under beds, which is where moths will most likely be.

How Do I Get Rid of Moths In My Persian Rug?

The most effective way to eliminate moth in a rug is to have them washed by a professional rug cleaning facility that has an intensive deep cleaning process.

I’ve said it before, but I’ll say it again: it’s better to be safe than sorry in these situations. This will fully eliminate the infestation in your rug.

If your budget absolutely does not allow for a professional rug cleaning procedure, you can lay your rugs out in the sun, rotating front and back, over the course of a few days to see if this helps.

Keep in mind that rugs with long piles will still have “dark spots” that the larvae and egg may be safe inside of.

We recommend thoroughly brushing the rug periodically to assure that different areas of the rug get exposure and brushing and exposing the rug to the sun again in 4-10 days for any eggs that may have hatched.

We haven’t found any moth sprays that are particularly effective.

In general, we don’t recommend spraying pesticides in your house without conducting research on the matter and knowing what the proper protocols are for undertaking such an endeavor.

Pesticides have been linked to cancer, ADHD, Alzheimer’s disease and birth defects.

Using Freezing and Heating to Eliminate Moths

Extreme temperatures can eliminate moths.

Sealing infested items and placing them in freezers for several days is an effective way of eliminating them.

As far as heat goes, because items have to be heated to pretty extreme temperatures, it’s generally not recommended to wash anything in water hot enough to eliminate moths, and rugs in general should never be washed with warm water.[2]

The following is a comical representation, not a suggestion that one should light their closet on fire to eliminate a moth problem.

Moth Balls For Rug Storage

Moth balls can be somewhat useful in preventing infestations.

Mothballs are designed to be used in closed containers to eliminate moths by suffocating the moths in the fumes within the container.

The problem is that area rugs can’t be stored in air right containers, as they will begin to rot over time.

They are not meant to be used in a storage facility (and especially not in your home) to prevent moths from reaching your rugs when they’re rolled up as a fool-proof way of preventing infestation.

If you’ve ever paid the price of forgetting to spray just one area of your body with mosquito repellent spray, you’ll know that you’ll need a thorough inch-to-inch coverage here too; otherwise, the moths will gather up in a safe zone where moth balls aren’t present.

Taking your rugs out of storage and inspecting/vacuuming them every three to six months is the best way to assure your rugs are safe in storage.

There are products such as MasterBlend’s moth repellant that can be applied by professional rug service providers which may prevent new moth infestations from happening in your rug.

We haven’t personally tested these products, but from what we’ve heard from three different reputable rug experts who have used the product, they are effective.

How Do I Prevent Moths In My Home?

  1. The best way to save your rugs from moths is also the simplest: just vacuum your rugs at once every two weeks, especially the areas that are under furniture. When vacuuming your rugs, be sure to vacuum both the front and the back of the rug. For areas you can’t vacuum, set clothes moth traps as a way of monitoring moth activity.
  2. Regular rug cleaning can help prevent moths, according to a study done by UC Davis on moths “fabrics with food, perspiration, or urine stains are more subject to damage.” Professionally cleaning your rugs at least once every six months to once every two years depending on your circumstances will help create certainty against damage.
  3. Establish a habit of checking susceptible areas and vacuuming them at least once a year. This includes closets, curtains, drawers, and any other area where darkness and natural fibers are present. Also regularly vacuum carpets, drapes, upholstered furniture, pet bedding, closets, cracks and crevices in floors, and areas inside and behind heaters, furnace air ducts, and vents. Particularly susceptible areas that are under furniture that is seldom moved and along baseboards where wool lint may accumulate. After using the vacuum, empty the bag because it may contain eggs or larvae.
  4. With storage items, cedar, and moth balls are recommended only if they’re properly sealed and stored.
    • Lavender oil or dried flowers are non-toxic, natural moth deterrents. However, it is not effective on larvae.
    • Cedar blocks are non-toxic and a natural deterrent. When used in a sealed container, red cedar contains oils that will kill larvae.
  5. Anecdotal evidence from our own experience suggests that rug pads also help prevent moth infestations as even the cheap ones are often treated in the production process to be moth repellant, while rugs are not. We have never seen a rug with a rug pad succumb to a moth infestation, though this could be correlational.
  6. Because moths like dark, secluded, and undisturbed environments, another option is simply to keep a light on at all times in any area of your house that doesn’t frequently receive traffic and to rotate your rug periodically. A salt lamp may work as well. Periodically rotating your rugs will also assure that the rug receives even wear throughout its lifetime, protecting you from area-specific wear and sun damage.
Moths like dark places, so it's good to keep your rug easily accessible for regular cleaning and maintenance.
