For a belt and braces job, you may widh to also lift the edges of affected carpet and spray the back of the carpet, as the casemaking clothes moth may chew the knots holding the pile onto the backing material or even feed on the backing material if it comprises of a natural fibre. You can also use a moth killer dust under the carpet and furniture such as, Pro-Active Dust (diatomaceaous earth). Pro-Active Dust is very long lasting if kept dry, up to ten years moth killing ability can be expected This dust is a natural product and therefore is very safe, although we suggest a mask when using, as it will dry the nasal passages rapidly if inhaled.

There are differing views as to what area you need to apply insecticide when dealing with Case Making Carpet Moth, generally, treatment around the edges of a room and under any furniture will suffice. By “edges of the room” we mean to treat a band approximately 500mm wide out from the skirtings. This treatment will last around 3 months, re-apply if necessary.

External walls are the most high risk area as the carpet abutting external walls is generally of a higher moisture content, which the moth prefer over a totally dry carpet!
