SINGAPORE: Tampines estate from June will start a new environmentally friendly enzyme treatment to control the cockroach population, said Tampines Town Council in a release on Sunday (May 7).
Called Cockroaches, Mosquitoes and Odour Removal (CMO), the new water-based treatment uses enzymes from edible plants to attack pathogens in cockroaches. This will upset the pests’ metabolic system, resulting in carbon dioxide gas to be released in their bodies, killing them within five hours.
The treatment can also control the cockroach population as cockroaches infected by it can infect other cockroaches through contact. Resultant eggs from the infected cockroach will also be infected.
While deadly to cockroaches and mosquitoes, the solution is harmless to humans. In addition, it does not contaminate water as it does not contain any chemicals or pesticides.
In October 2016, a month-long trial of the enzyme treatment was conducted and was found to be effective. Tampines West will be the first to start the treatment in June. From July, it will be extended to all the other divisions in Tampines.
Speaking to Channel NewsAsia at a demonstration of the new treatment, Member of Parliament (MP) for Tampines GRC Baey Yam Keng said that while the new treatment is more expensive, it will be more cost saving.
"With lesser frequency of having to spray this at the chutes, and expected better results in terms of controlling the number of cockroaches, we believe that this will end up being a better, more cost-effective method for us," said Mr Baey.
He added that Tampines Town Council will provide subsidies to its vector control operators to help kickstart the new treatment.
