optimal air born suspension and insect impaction. In dry climates evaporation will tend to cause
droplets to “shrink”. Therefore it may be necessary to increase flow rate to get adequate
coverage. The smaller the droplet size the greater the number of droplets that are created. For
example: If 1 milliliter of spray is dispersed as 20 Micron droplets, there will be 239 million
droplets produced. For the same spray mixture using 100 micron droplets, only 1.91 million will
be produced. The large quantity of droplets greatly increases the chances of contact being
made with the insect.
According to the WHO Pesticide Evaluation Scheme, the time required for a droplet to fall 10
meters is defined in Table 1 below.

The recommended droplet for Mosquito control is 10-20 Microns. For Fly control approximately
30 Microns. For Bedbugs, spiders and other crawling insects where a slight residual is desired,
20-40 Microns droplets are affective depending on insect type and type of formulation being
used.

5.2
Odor Control
Depending on the type of environment and odor source, droplets for controlling odors can be in
the 20-30 Micron range and even larger i
f a “residual affect” can be tolerated.
5.3
Disinfecting
Disinfectants are designed to be applied to non-living objects to destroy microorganisms.
Typically a disinfectant for objects or surfaces is more affective when applied in the 30-50
micron range. However, smaller size droplets in the 10-20 micron range can be effective when
targeting microorganisms suspended in the air.
