Foggers turn insecticides and pesticides into droplets that remain in the air for a certain period of time, filling a room or property with a choosen treatment. This method of treatment can control large pest infestations in areas like schools, warehouses, and barns.
Before you start using an insect fogger or other foggers, it’s important to know how fogs work so you can use the equipment correctly and in the right context.
First, it is important to know that there is a difference between a fog and a mist.
Fog produced from a fogger has very small droplets of solution, 50 microns in diameter or less. For comparison, a human hair is about 100 microns in diameter. This results in a true fog, where the droplets are nearly imperceptible. They remain suspended in the air until they evaporate.
Particles that are 50-100 microns in diameter are called mists. Mist particles will fall out of the air and coat the surrounding surfaces in the solution. This isn’t to say they are not as good as fogs, but they will perform a different function.
Different equipment will produce different results, so it is key when using insect foggers, electric foggers, or ULV foggers to understand your purpose and goals when using these products. For example, the target droplet size for pest control fogging should be small, but under 10 microns, the product can evaporate out of the air faster than it can affect the target insects. Conversely, if the droplets are too large, they won’t be able to remain suspended in the air and will coat the ground instead.
Using Pest Control Fogging Equipment
The goal of using fogging equipment is to get the droplets of your product to atomize and remain in the air for a certain period of time. This type of equipment can be used in several applications outside of pest control, including odor control, disinfectants, humidity control, sanitizing, etc. and you can purchase many types of units and products to suit your needs.
Before choosing your fogger, determine how large of a space you need to treat. Homes, bakeries, restaurants, warehouses, attics, etc., may require a larger machine that is able to produce a large volume of fog or mist to control food and clothes pests and other common pests, like the Commander Tri-Jet Fogger. Smaller, more portable foggers, like the compact Fogmaster Jr, can be used for treating plants with insecticides or soaps, treating pet stains, and treating odors in small spaces.
