MAKING MOSQUITO COIL

 

 
Introduction

Mosquito coil is mosquito repelling incense usually shaped into a spiral; and typically made from a dried paste of pyrethrum powder. The coil is usually held at the center of the spiral, suspending it in the air, or wedged by two pieces of fireproof netting to allow continuous smoldering. Burning usually begins at the outer end of the spiral and progresses slowly toward the centre of the spiral, producing a mosquito-repellent smoke. A typical mosquito coil can measure around 15 cm in diameter and lasts up to 8 hours. Mosquito coils are widely used in Asia, Africa, and South America. The Production capacity is 312,000 boxes per year bringing estimated revenue of US$ 600 annually having invested US$ 76,304. Mosquito repellent coils are one of the most popular means of driving out mosquito and insects out of the houses. The mosquito repellents are comparatively harmless with the main constituent pyrethrum extracted from the flowers of pyrethrum. In Uganda, there is a high prevalence of mosquitoes mainly
because of the high rainfall coupled with the warm weather favourable for breeding. Setting up a plant to make mosquito coils would help to fight mosquito bites and reduce malaria incidences.


Production Process, capacity and technology

The raw materials are blended, kneaded and crushed. The mixture is extruded in the form of flat belt and cut by an air-blower. The belt shaped material is converted into moulds of double coils by a Rota stamping machine and finally packed in cartons. The plant profiled has a minimum capacity of 1,000 coil boxes per day.


Market Analysis

There is good market potential because mosquitoes are a menace and malaria prevalence is quite high. A mosquito coil requires no electricity and is affordable in rural areas. However, this Industry is not yet developed in Uganda.
