ULV fogger operation

When it comes to foggers Ultra Low Volume foggers or ULV foggers for short are one of the best option to choose, because these foggers are able to produce much finer mist than any propane or electric foggers therefore they can be used outdoors and indoors for many different applications from mosquito control up to even disinfection.

If you either already own an ULV fogger or are about to purchase one, you need to know how to properly operate it, because that is the key to efficient fogging and great results. So here is an ULV fogger operation manual with some tips and tricks how you can get most out of you ULV fogger.

  1. First things first, to be able to work ULV fogger you need to connect it to an electricity source. This means that you simply need to plug the fogger’s power cord into an outlet and you can start fogging. But if you do this first time, make sure you check what kind of voltage the fogger requires, because you don’t want to plug a 110 volt fogger into 220 volt power outlet or the other way around.
  2. After you have plugged the fogger into an outlet, you can take the next step in operating the ULV fogger. Next you need to calibrate the fogger. What that means is that you need to turn the adjustment knob to the liquid flow you want. As you increase the flow rate, droplet size the fogger emits will increase too. Larger droplets are more suitable for applying liquids such as disinfectants or chemicals, because they settle better on surfaces, but smaller droplets and therefore flow rate is better for insecticides or pesticides, because they stay in the air longer and therefore can better kill insects.
  3. Of course you need to also actually fill the liquid tank with the liquid you want to use. You can do it either by opening the seal to the liquid tank or unscrewing the liquid tank depending of which model of ULV fogger you own. Just make sure to not mix any liquids in the tank, better do it before, and also make sure the liquid you want to use is suitable for a ULV fogger and don’t overfill the tank. Then put on the cap or screw the tank back on the fogger and you are good to go.
  4. Now that all the other steps are done you can turn On the fogger and fog either outdoors area or indoors spaces with the liquid of your choice. Make sure you calibrate the fogger before you turn it ON because if you do it in reverse you are risking getting either sprayed in face or in an area you didn’t want to spray.

After you are done fogging there are also a few things you need to know to completely turn the fogger off and maintain it in good condition so you can use it next time you need it.

  1. For most foggers the proper way to turn them off is this: first turn off the flow rate adjustment knob, which will make sure the fogger stops emitting the fog and only then turn off the electricity completely because if you do it the other way around the fogger can start dripping the liquid into the foggers hose that in time can destroy the motor of the fogger. Then after the fogger isn’t connected to electricity anymore you should open up the liquid tank cap to air it out a bit.
  2. After you have done previous steps you should always empty out any remaining liquid from the tank and flush it with water, because this ensures that any chemicals don’t remain in the tank and do any damage to it.
  3. Also you should check things like the spray hose and electric cord quite frequently to ensure that they haven’t acquired any damages.
  4. Then all that left to do is to put on the protective nozzle and store it in a safe place (best in a dry and cool location, out of direct sunlight) for the next use.

Additionally most ULV foggers have filters on the bottom of them, because they protect the motor from the liquid, so you also should replace those filters from time to time for the fogger to work in its full capacity.

Also I recommend fogging in the mornings or afternoons and in low wind and dry conditions because that will ensure that you get the best results.
