The insecticide in the fog is not harmful to human at the low concentrations used and it has no odour. Residents are advised not to be concerned about the fog, and are also requested to leave their doors and windows open when the fogging machine is in their area, so that the fog can kill mosquitoes inside the house. 

We Provide Fogging and Spraying for Mosquitoes. To kill mosquitoes, flies, biting flies, gnats and other annoying, flying pests, use Pyrethrin fogging material. Pyrethrins are derived from a natural source and are widely used in the pest control and mosquito control for a quick knock-down of targeted pests.
