DIY ULV Fogging/Misting Information

You do not require a license to do disinfecting treatments.
You may require a license for vector control treatments.

Insecticides recommended by Mosquito Management are approved by NEA for use by professional vector control technicians as well as the general public.

Most foggers should have two knobs/dials. One controls blower speed, the other controls the valve to the insecticide. Generally, you will want to set your blower speed to the maximum to increase the reach of your mists. As for the insecticide valve, unless you have the more powerful Pioneer Electrical Fogger, you will want to completely open the valve to allow more insecticide to be misted out. The Pioneer will require you to slightly close the valve so that you do not over mist your insecticide. We will provide a quick course on misting upon delivery of the fogger and its accessories.

Remember to always wear your personal protective equipment (PPE) for your own safety.

As a refresher:

Always remember to wear your PPE for your own safety.

Never spray upwind/against the wind.

Never spray directly at people or animals.

For outdoors - Mist upwards so that the mist can slowly float and settle on the landscaping. Aim at plants and dark areas such as cracks, holes, underneath the furniture where mosquitoes will most likely rest from the sun. Mist at least 2-3 times a week.

For indoors - Ensure that no one except you is in the house and close all windows. Start with a room and mist upwards so that the mist can slowly float. Aim at the darker areas such as under furniture as well as the curtains. Close the door and continue with each room until all rooms are done. Mist the rest of the house (hallways, living room, etc.). Once done, exit the house for at least 15 minutes. After 15 minutes, you may open all windows and doors to ventilate the house. Indoor misting is not as necessary as outdoor misting and can be done less frequently at once a month. Generally, if you can solve your outdoor problem, you will have no problems with indoors.

Most organic insecticides are oil-based which has a tendency to clog up the nozzles when dried. To prevent this from happening, always make sure that you empty the insecticide from the fogger into the provided container after misting. Fill the fogger with plain water and turn it on for about a minute to flush the nozzle. Empty out the water after flushing.

Misting (and thermal fogging) only kills adult mosquitoes and have a weakened effect against larva stages of mosquitoes.

An Integrated Pest Control (IPC) approach is recommended.  This means that proper housekeeping must be done additionally to ensure that no breeding takes place at your premises.  This means making sure that you remove anything that has a tendency to collect water. For those that are unavoidable (ie. drains), larvicide can be used. These can be found in nurseries and are generally safe to use.  Mosquito traps can also be added as part of the IPC approach.
