Wool Moths And Prevention

Clothes Moth  Avoidance  

The best moth prevention is to avoid conditions that favor moths. ​The rug to the left was wrapped for storage to protect the rug from moths.

Unfortunately, the rug had already harbored moth eggs; after wrapping the moth larvae, it hatched and devoured the rug, leaving a nasty surprise for the rug owner. 



  • Keep wool rugs clean with regular vacuuming, look for any signs of insects or damage, and clean wool rugs every two to four years or when rugs look dirty.  Many household soils (protein, cooking oils) improve the environment for moth Larevae tho thrive by increasing wool's moisture retention and protein food source. Higher moisture retention is essential for clothing moth larvae to have enough moisture to live while they consume textiles. 

  •  Clothes moth larvae have no protection from sunlight/UV radiation. Instinctively, moths always seek out dark, undisturbed areas to lay their eggs under a sofa, end table, or bed.  

Blocking Access to textiles

  • Block adult month entrance to your home from outside; Adult moths can enter the home via an unscreened door or window, so minimize open/unscreened doors and windows that allow easy accessto clothes moths

  • Newly acquired textiles are a common infestation source, a trojan rug of sorts. Moth eggs are microscopic, so a new to you carpet can harbor unhatched wool moth eggs that subsequently hatch with voracious moth Larevaein eating their way through textiles in your home. Even Moth Larvae can hard to detect in active in thick rugs 

  • Vacuum floor coverings regularly with extra attention to dark areas under sofa's and beds Vacuuming alone will not kill all clothes moth Larvae or eggs but will reduce the possibility of infestation. Moths seek out natural finers 

  • Freezing is often cited for killing clothes moths but home freezers do not reach the 0.F- / -17.C needed for reliable, effective freezing.  repeated cycles of freezing and thawing work best. 


  • Heat can be a better option; a clothing steamer works well for killing clothes moths particulalry smaller thin textiles, and steam on both sides is effective at killing clothing moths and their eggs.

  • "I'm only storing it for a little while" - That's all the time an adult wool month needs to lay its eggs on your rug; there is no such thing as safe for just a little time. Your home garage is the perfect place for clothing moths to hitch a rug on your rug and moth Larvae to snack on youor rug.

  • When storing rugs, they should be washed or, at a minimum, vacuumed first and wrapped in breathable material, heavy paper, or Tyvek to block entry to rugs. Improperly stored rugs, particularly in storage facilities or, as we call them, moth superhighways, is a common route of moth infestation. 

  • Never store rugs in plastic bags or plastic wrap make sure to use plastic bag made for garments wool needs to breathe, and plastic can cause a rug to mildew use heavy craft paper, old bed sheet, or Tyvek house wrap. 

  •  Natural repellents such as tobacco leaves, cedar oil, other essential oil, lavender sachets or storage in a cedar chest may have ancillary benefits and deter moths but none are a sure fire guarantee these may seem like the easiest or best way to deter months they should be used in combination. 

Clothing Moth Detection

  • Visual inspection of rugs can detect clothing moths, active moth Larevae infestation and damage. 

  • Pheromone moth traps do not kill ALL moths, only the males; they only let you know you have a wool moth infestation; they do not stop infestations. Moth traps are a helpful detection tool. 

 I found wool moths on my wool oriental carpet; what should I do now?

Act quickly!   



As soon as clothes moth are detected the infested textile or rug should be removed from the home or confined (wrapped in plastic) or air tight container to stop the infestation from spreading to other textiles and treated as soon as possible; the rug should be taken to a cleaner for professional treatment. Air tight containers workwell for sealing and other garments. 

Closing doors to a room with an infested rug or moving a moth-infested rug to the garage is inadequate for confining the infestation. Moths are small; they can fly and crawl under closed doors. By the time the infestation is detected, wool moths may have spread to other rugs and textiles.


Treatment of the infested rugs to kill moth larvae is straightforward.  A trip to the dry cleaners for small items. Dry cleaning is effective at killing clothes moth larvem and kill moth eggs let your dry cleaner know you have a moth issue.

Larger textiles like rugs should be removed form the home treated with pesticides to kill the moth Larevae and eggs and then thoroughly washed. You may chjoose to have rugs treated with moth proof spray there are some downsides to these.

Typically, when an infestation is detected, moths have had access to your home and often lay eggs elsewhere on other protein fibers, rugs, wool clothing, and upholstery. 


We cannot emphasize that removing and treating the infested rug or textile are often NOT enough. it's often a whole house issue in need of professional service.

We strongly recommend contacting a professional pest control company to perform on-location pest control/ mitigation. 

 What Doesn't Stop or Control Clothing Moths


Let's start with the big one: cedar shavings & and blocks don't work; we have pulled active infestations out of cedar boxes and cedar-lined closets. Additionally, Lavender, tobacco leaves, and oil extracts don't work, we wish they did. 

While these may have a mild benefit, we have pulled countless moth-infested textiles out of cedar chests, cedar-lined closets, and various satchels of tobacco, lavender, and other herbal treatments. These may have ancillary benefits, they do not work

Bug bombs/Holliday foggers while these kill the adult moth and larvae, they do not kill eggs. Fumigation is multi-step stratgy timed with the hatching cycle of clothes moths

Mothballs (naphthalene) work in tightly enclosed spaces, not open spaces wrapping a rug is effective and without the mothball smell. 

The mothball odor can be difficult to remove and often requires washing. 

Again, we strongly recommend a commercial pest control service when an infestation is detected in your home.
