To kill mosquitoes, flies, biting flies, 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. Using a natural substance for a quick kill has been popular for a long time. With the increased awareness of mosquito borne disease (West Nile Virus, Malaria, etc.) many house owners in Malaysia are opting to control mosquitoes on their property. Pyrethrins are perfect for killing flying pests on patios, shrubs, ground cover and other areas where biting bugs congregate or attack humans. The most obvious characteristic of Pyrethrin spray or fog is that it has no residual. This is great if you need to fog areas such as restaurants, homes or warehouses. If you need a residual (or longer lasting effect) spray or fog, add Permethrin (a synthetic or man-made pyrethrin) to your fogging solution.
When fogging large areas indoors or outdoors, the preferred respirator mask is a simple type with replaceable cartridges. A half-mask type respirator is the most popular type used to avoid inhalation of spray or fog particles.
