Wool Moth Infestation 

Wool moths seek out protein fibers such as Oriental carpets but moth infestation happens in other protein fibers such as feathers, Alpaca, and animal skins. These moths lay eggs, and when the eggs hatch, the larvae have a voracious appetite for protein fibers such as wool, and moth infestations can be devastating to the look and value of Oriental rugs.

What Are Wool Moths?

There are two types of wool or clothes moths in North America — the webbing clothes moth (Tineola bisselliella) and the casemaking clothes moth (Tinea pellionella). 

 

-Webbing clothes moth (Tineola bisselliella) Adult webbing clothes moths are a uniform, buff color, with a small tuft of reddish hairs on the top of the head. They make a webbing, seen in the photo to the left, similar to spider webs but thicker.

Case-making moths (Tinea pellionella) are similar but have dark specks on the wings. They make a casing similar to a rice hull in size. 

 

Adult moths of both species lay about 40-50 pinhead-sized eggs on protein fibers; when the eggs hatch, they feed on protein fibers. 

The larval stage of clothes moths is tiny white caterpillars a quarter to half-inch long. Development time from an egg into a moth varies significantly from one month to a year, depending on temperature, food availability, and other factors. 

 

 The larvae favor concealment from light, and direct sunlight can kill the larvae, so moths lay their eggs in areas with little light exposure under sofas, beds, and end tables.

 

As larvae eat, they destroy fibers and leave threadbare areas and sand-like gritty fecal pellets.

Signs of Wool Moths 

Wool webbing and casing moths are small, about the size of common pantry moths.

Since they seek out dark, undisturbed areas, Moth infestation and damage can go undetected. 

Fresh moth damage (above) shows signs of damage, debris from the moth's eating wool, and a loss of wool pile as shown.

 

Signs are loss of pile webbing and small casing the size of rice but Flat.  Vacuuming monthly and visual inspection in dark areas is the best preventative step

Getting Rid Of Moths

Confine

 

The infested textile should be removed from the home or confined (wrapped in plastic) to stop the spread of infestation to other textiles and treated as soon as possible.

Closing doors to a room with an infested rug or moving to your garage is inadequate for confining the infestation. 

Treatment

Treatment of the infested rug killing and removal of moth larvae and their eggs by washing is a straightforward process we perform all the time. We cannot do this in your home it takes days to get rid of moth in Carpet.

However, removal and treatment of the infested rug/ textiles are often not enough. Typically at the point infestation is detected moths have had access to your home and often laid eggs elsewhere on other protein fibers such as other rugs, wool sweaters, socks, or protein-based fibers. it's a good idea to wash cloths made from wool and other protein fibers to kill any possible eggs   

 

Rug Cleaning

Keeping rugs clean helps limit moth infestations and cleaning new to you vintage rugs before taking them into you home reduces to possibility of moth infestation 

 

We strongly recommend contacting a professional pest control company to perform on-location pest control/ mitigation in addition to treating and cleaning viably moth-infested rugs. It's an involved process to get rid of moths in your home. Failure to treat the issue as a whole house infestation often results in reinfestation and additional damage.

Before freezing, put the rug in a plastic bag, squeeze out the air, and seal it. Take it out of the freezer, allow it to come to room temperature for a week, and re-freeze do this several times.
