Carpet Moth Infestation 

If you have an active moth infestation with a rug in your home we strongly suggest you contact a professional pest control company. Renaissance can remove and kill the moth in your rug often by the time an infestation is discovered moths have often moved the site of infestation to other areas of your home and laid eggs. All proteins fibers are susceptible to infestation rugs, sweaters, socks, blankets wool, alpaca, angora. 

What doesn't stop or control moth infestations 

Cedar, lavender & Essential oils may have a mild benefit we have pulled plenty of moth infested textiles out of cedar chests, cedar lined closets over the years.

Bug bombs/Holliday fogger kill the adult moth and larvae they do not kill moth eggs. Eggs are microscopic and impossible to detect

Dealing with the one rug in a home with visible infestation damage and neglecting the other rugs in the home. For example, assuming that since the infested rug is at the far end of the house in a guest bedroom wool textiles in the rest of the house should be ok.


Moth Pest Treatment Methods


Freezing is an effective method to control an active infestation. It’s generally recognized that temperatures of -20 C. (-4.F) are needed to ensure eggs are killed and for a period of one week. Often textiles are allowed to thaw for several days and multiple treatments or freezing and warming to shock any survivors of the initial freeze. Wet textiles should be dried first before freezing to reduce the possibility of damage from water ice expansion and crystallization.



Temperatures of 45 C. (113 F.) has been shown to kill insects in all stages of development in a matter of several hours. It’s important that the core textile temperature reaches this temperature, not simply the room the textiles are in. The two-hour treatment should begin when the textiles have reached 45C. (113F.)



The use of washing as a treatment has shown minimal effectiveness by itself. However, hot water 130. F and steam particularly, with pretreatment of insecticides are effective but this increases the risk of color run, shrinkage, and felting so this method is not practical for many textiles.


Dry cleaning

Dry cleaning solvents are effective particularly when combined with heat the limitation is the size of the textile and nature and condition of the textile to be treated.



Mothballs/Crystals (Naphthalene, para-dichlorobenzine).

Work in enclosed environments and in high concentrations. Carpet beetles are not as sensitive as webbing & casing moths. Additionally, long term exposure can cause staining and discoloring with some textiles and the odor permeates textiles which are objectionable to some and requires a subsequent washing to remove.




Pesticides are effective at dealing with adult moths and larvae but not unhatched eggs. As such multiple treatments are required.
