Katól is the generic term that Filipinos use to refer to a coil that is burned to kill or repel mosquitoes. It is actually a brand name of a product of Azumi & Co., Ltd. of Osaka, Japan. The company used to export insecticides as far away as Spain in the early 1900s.

Katol is one of the few Japanese words that have entered Filipino vocabulary, although few people know of its origin.
A katol is often dark green in color. The photos on this page show the less common colors of blue/green and red/pink. Katol is often burned at night and sometimes is potent enough that you don’t need a mosquito net over the bed. A popular brand in recent years is Elephant.
The company Baygon also manufactures katol in the Philippines.
Here is a commercial for Dragon Katol.
Dragon kung umusok, Lamok siguradong tepok.
** Burning one mosquito coil is as dangerous as burning 75 to 137 cigarettes because of harmful chemicals like formaldehyde, octachlorodipropyl ether and bischloromethyl ether.
