In the case of both carpet beetles and clothes moths, the appearance of adults typically means that at least one infestation is present. Locating infestations requires thoroughly checking areas where fabrics are stored-in closets and drawers, under furniture that has not been moved for several months or years, and underneath carpets and rugs.

Once the infestation has been located (bear in mind there may be more than one infestation, and all sources must be found to protect against future infestations) the next step is removal of the damaged material. All fabrics in the location should be washed according to manufacturer’s instructions, or thrown away. Both carpet beetle and clothes moth larvae can be killed with washing in hot water, or drycleaning.

Pesticides can be used to treat crevices and cracks to prevent future infestations. However, most household pesticides that are safe to use on fabrics will not provide more than approximately six months’ protection from pests.

Regular vacuuming will go a long way towards preventing reinfestation with both carpet beetle and clothes moth larvae. Area rugs should be vacuumed on both sides, and rotated or rearranged periodically. Heavy items of furniture should also be rearranged from time to time, so as to expose new areas of carpet and prevent the creation of the dark and undisturbed habitats that fabric pests favor.

Clothing and other textiles should be stored in airtight, well-sealed containers. Mothballs and other insect repellents can be added to containers; however take care that these are not allowed to touch any items made of plastic, as mothballs may soften and melt plastics, causing them to stick to fabrics.

Small items such as toys and ornaments that cannot be washed can be placed in the freezer to kill both larvae and eggs. These should be stored in the freezer for one week to ensure all eggs are killed.
