In Malaysia, Mosquitos are regarded as annoying pests which cause red, itchy marks on our skins through their bites. These insects may be tiny, but they are clearly public enemy number one.
These vectors, carriers of harmful viruses and bacteria, are responsible for spreading many diseases such as dengue, malaria and zika. In fact, mosquitoes cause over 80,000 dengue cases with about 170 deaths per year. It is likely that the presence of mosquitoes could put yourself and your employees at risk.

• Exclusion -  Prevent mosquitoes entry with window screens and netting
  
• Restriction - Eliminate breeding grounds and harborage sources for mosquitoes such as stagnant water in pots and basins.
  
• Treatment (Destruction) - Innovative, market leading solutions such as larviciding and fogging to bring mosquito infestations under control.
  
• Monitoring - Ensure protection measures such as ovitrap and adult mosquito trap continue to work after control is achieved.
