Treatment Method for Case Making Carpet Moth

This moth is highly destructive and often astounds the homeowner with the extent of damage caused.

The Case Bearing Carpet Moth will normally attack high wool content carpets although will not restrict itself to this food source, it can also feed on clothing and cereal products.

Generally, this moth can be found around the edges of the carpet and more particularly under furniture, even furniture that is directly placed on the floor ie: with no legs

The most effective method of treatment is to spray the affected carpeting with a water-based insecticide such as Pro-Active C comes in a 1 litre ready to use trigger spray to kill moths or we also offer the 5-litre containers of moth killer spray. For a belt and braces job, you may wish to also lift the edges of the 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 natural fibres. You can also use moth killer dust under the carpet and furniture such as Smite (diatomaceous earth). Smite is very long-lasting if kept dry, and up to ten years of 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 wideout 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 prefers over a totally dry carpet!
