Eagle Naphthalene Balls are a long-established household staple in Sri Lanka, sold under the Eagle brand and manufactured by SONS Organics (Pvt) Ltd. Made from refined naphthalene derived from coal tar, each ball is a small, white, crystalline solid with the sharp, distinctive odour that most households immediately recognise. The packaging describes the product as Refined Snow White Pure Naphthalene Balls, with a stated purity of 99% UP.
Naphthalene works through sublimation — it converts directly from a solid into a vapour without passing through a liquid stage. That vapour acts as a fumigant, providing protection from silverfish, moths, cockroaches, and other insects. Because the product works this way continuously, the packaging itself acknowledges that some weight loss through evaporation is unavoidable over time.
The balls are intended for use in wardrobes, bookshelves, kitchen shelves, cupboards, and toilets. The label directions advise placing the balls into the intended space immediately after opening the wrapping. When used in wardrobes or on bookshelves, the balls should not come into direct contact with clothes, files, or books. Any unused balls should be stored in an airtight container to slow evaporation between uses.
Safety precautions are important with this product. The packaging cautions that naphthalene balls must be kept away from the reach of children and pets at all times. Buyers should read and follow all label instructions carefully before use and use the product only as directed on the packaging.
The option ladder on this page includes the Cavadi Eagle Naphthalene Balls listing as well as the Lakpura Naphthalene Balls in a 400 g bag. The 400 g bag contains approximately 220 balls. Both are supplied in bag format and share the same Eagle brand formulation.
