The larva spins a silken tube which is used for protection. It gets its nourishment from the natural fibers of the handmade area carpet. The webbing moth attaches its tube towebbing moth larvae a dark area in the fibers and makes itself stationary so it feeds in just one are of the area carpet. The larvae stage itself can last as long as 2 years so you can see it could create a lot of damage to your oriental rug if left unchecked.

Unlike the moths you are familiar with, the carpet moth prefers dark areas and areas that have low traffic. The moth itself does no damage to your handmade area rug because once it becomes an adult moth it no longer feeds. Its only purpose from that stage on is to reproduce. It is the larvae that does all the damage by eating the fibers. Once the larvae hatch they leave a tiny cocoon shell that looks like a piece of rice. There is not a Vancouver carpet moth, no native cloth moth In Vancouver. These moths have generally come from Western Eurasia. They have the ability to eat keratin protein from wool and silk making them devastating to your homemade area rug. They prefer dirty area carpets which have organic material for a food source. Stuff like human skin or sweat, dirt as well as food scraps or human or pet hair. They do not need liquid to survive they only need moisture. They can actually survive in a mixture of natural and synthetic fiber carpets or just synthetic fiber carpets if there is enough of a food source caught in the fibers. You can tell if your carpet has been infested with the moth in a variety of ways. If you see adult moths flying around the house this is a bad sign. If you take a close look at your handmade area rug you might see loose fibers sitting on the top surface of your rug. This is from the larvae snacking on the natural fiber knots that are at the base. You might actually see the cocoons themselves but they are quite tiny and tend to be spun in the same color as the fabric to blend in to the carpet so they will not be detected. It can look like little rice grains. You might actually be able to see the larvae themselves squirming around the top pile of the area rug itself. The best way to try to prevent moth damage is to make sure you keep your area rug as clean as you can. This might mean getting your handmade carpet cleaned once a year for preventitive measures. But most importantly vacuuming on a regular basis and avoiding getting food or organic liquids in your persian rug. The cleaner you keep your carpet the better your chances of never having a moth problem. vancouver moth damaged carpet There are a variety of ways to eliminate carpet moths.

There are quite a variety of different insecticides made from different chemical compounds. Some are more toxic then others and some can be quite toxic to pets. Some of the more popular insecticides include permethrin, pyrethroids, and bifenthrin. Biological Method –  Camphor is a natural terpenoid that is an alternative to mothballs. It needs high concentrations to be effective. Lavender leaves with an additional few drops of lavender leaves can be effective in some situations. Trichogrammatid wasps are a very insect that are harmless to humans and will place eggs in the larvae and eat the larvae.  Physical Methods – Putting your carpet in bright light and brushing the pile back and forth exposing the larvae to light and dislodging the larvae might help. Freezing the carpet for 72 hours at a temperature of – 18 degrees fahrenheit or – 8 degrees celcius should do the trick. Alternatively you can use heat. You need to keep your oriental rug in a place that is 120 degrees farhenheit or 49 degrees celcius for a couple of hours.
