House flies are commonly found at homes and business premises in Malaysia. They are known as vectors of pathogen because they carry the pathogenic bacteria such as Escherichia coli and Salmonella after contacting to animal waste. It is therefore very much essential to control over the house flies so that it cannot be spread out in a large scale. In doing so, many kinds of baits are used to attract and trap these flies either by mechanical or chemical means. But all these baits are not capable of attracting flies equally. The main goal of this study is to find out the best bait that can attract house fly effectively and safely in everyplace. Experiments were conducted to find out the best bait among six different baits commonly used in Malaysia. Two baits made in abroad and four baits made in Malaysia were selected for conducting this study because these baits are commonly used in Malaysia. Experiments were carried out in food industry, fish market and poultry farm in the east coast of Malaysia. Data were collected from the field experiments continuously for six days and analysed to determine the best bait that trap the house flies very effectively. Data analysis results show that the Chinese Electronic Fly Catcher Trap (CEFCT bait is the best one for trapping house flies effectively compared to other baits. Further studies are necessary to find out the low-cost bait components with similar effect of CEFCT bait in local market in order to develop new low-cost bait.
