The following link is to technical material published by Pulsfog on the use of foggers for insect control. It is aimed primarily at the use of foggers out-doors for insect control particularly mosquitos. It does however contain useful information on droplet size etc. using various combinations of carriers. The safety section is also useful in terms of providing basic information on safe ways to combine chemicals for application.
