Do you need to fog an area for pests or other reasons? If so, you may be wondering what the best way to do that is. One option is a ULV fogger. What is a ULV fogger? Let’s take a look.

An Ultra-Low Volume fogger is a device that is used to create a fog or mist. It does this by using a small amount of liquid, which is turned into a fine mist by the ultrasonic vibrations of the machine. This type of fogger is often used for pest control and disinfection.

Below, I will take you through some of the key features of a ULV fogger, and I will also share my thoughts on whether or not this type of machine is right for you.

ULV Foggers: The Basics

As I mentioned above, a ULV fogger uses ultrasonic vibrations to create a mist or fog. It uses large volumes of air at very low pressure to move the liquid. This mist is then released into the area that you want to fog.

There are a few different types of ULV foggers available on the market. Some work by using an air compressor to create the fog, while others use a heated element to turn the liquid into a vapor.

One key thing to keep in mind with a ULV fogger is that the mist created is very fine. This means that it can travel a long way and cover a large area.

It is also important to be aware that the mist will settle over time, so you may need to re-fog an area if you want to maintain the desired level of coverage.

It is also worth mentioning that ULV foggers are used for cold fogging. This means that the liquid is not heated, and it will not cause any damage to surfaces or equipment.

Are ULV Foggers Effective?

ULV fogging is actually one of the most effective ways to treat an area for pests. The fine mist created by the fogger can reach areas that are difficult to get to with other methods, and it can also stay in the air for a long time.

This means that you can achieve a high level of coverage with minimal effort.

To be more specific, the particles from a ULV fogger range 5-50 microns in size. This is small enough to penetrate deep into cracks and crevices, where pests often hide.

The mist will also evaporate quickly, so there is no danger of it settling on surfaces and causing damage.

Advantages of ULV Fogging
