How Long will Fogging Last

Fogging is an insect-killing technique that involves the use of a thin pesticide spray (aerosol) controlled by a blower. A heated vapour may be employed in some situations to transport the spray and keep it aloft for longer. Pesticides with a short kill time, such as pyrethroids, are commonly used.


To put it another way, Fogging employs disinfectant sprayed from a Fogging machine to give the appearance of fog in a room. It's a good technique to disinfect a lot of horizontal surfaces, as well as hard-to-reach locations that are often overlooked or ignored, including small, restricted spaces like extractor units.


Although the number of approaches are growing when it comes to fogging, mentioned are a few commonly used techniques.

  • Chemical fogging

  • Chlorine dioxide

  • Titanium dioxide coating and UV light

  • Ultraviolet light

  • Vaporize hydrogen peroxide

  • Ozone

  • Ionisation

How long can the fogging last


Fogging is done for a minimum of 15–30 minutes in most cases to allow the fog to dissipate and the chemical activity to take place. After fogging, let a further 45–60 minutes for the droplets to settle out of the air and onto the surfaces.


  • Things to keep into consideration while going for fogging


If you want to disinfect surfaces with fog, mist, vapour, or UV treatments, talk to your manufacturers/suppliers (which could include fumigators) to see if they have a product or system that suits your demands. The treatment you use will be determined by the following factors:

  • the size and shape of the area to be treated, as well as how readily it may be sealed off while an airborne product is delivered

  • Soft furnishings may operate as a sink' for airborne pollutants and emit them for a length of time following treatment, whether there are hard or soft surfaces (remove items such as sofas before treatment)

  • The nature of your business — some locations may be better suited to UV surface treatments than airborne chemicals, or vice versa, if rooms cannot be sufficiently sealed to hold airborne chemicals, for example.

If you too are looking for professionals to carry the fogging you can contact Germ Radar for the exceptional services.
