This is really only used with Formaldehyde and related products. By thermal fogging - similar to misting but involving heating of the disinfectant to produce a fine vapour. The small particle gives the best penetration and suspension. Cheap and quite effective, but carries major health risks for animals and operatives. Importantly residues on walls can be released several days later.
Effects can be cumulative.
In view of modern concerns for health and safety the use of this chemical should be strongly questioned. Obviously it cannot be used in the presence of pigs. Glutaraldehyde - very similar to formaldehyde and burdened with the same risks. One extra danger is the absence of an unpleasant smell. Not efficient enough or safe enough for common use.
