Mosquitoes are most active during dawn and dusk, though they can be present throughout the day in forested areas. The wet season (May to October) sees higher mosquito populations, while the dry season offers some relief.
To protect yourself, use insect repellent containing DEET or picaridin, wear long sleeves and pants during evening hours, and ensure your accommodation has mosquito nets or screens. Many upscale hotels and lodges provide mosquito nets and repellent, but bringing your own supply is advisable.
Beyond the nuisance factor, mosquitoes can transmit dengue fever, which is present in Laos. Unlike malaria, dengue-carrying mosquitoes are active during daytime hours, so continuous protection is important.
