FLY CONTROL WITH D.D.T. 
The value of DDT as an insecticide to kill flies lies 
- principally in its residual action, that is, it remains effec- 
tive for a long period of time after it is applied. There 
are many other insecticides that kill flies quicker than 
DDT, for instance, Pyrethrum, but they have no residual 
value. Therefore, it must be remembered that to make 
DDT effective as a killing agent, one must build up, or 
leave on surfaces, a deposit of DDT; the heavier the de- 
posit, the more lasting the effect. 
DDT is prepared in two forms: one form, whereby it 
is dissolved in a solvent such as an oil or hydro-carbon 
solvent; and the other form whereby it is processed into 
a very fine powder of micron sized particles to which are 
added suitable wetting agents or diluents. 
In general, the DDT dissolved in oils or hydro-carbons 
are suitable for use around the house and in rooms where 
it is not desirable to build up much of a deposit of DDT, 
and where the main object of its use is to kill what flies 
are present at the moment of spraying, and where a heavy 
residue would be objectionable. The oil formulations of 
DDT should not be used on animals and are not safe 
where extremely heavy concentrations are to be applied. 
They are safe if used as one would use an ordinary house- 
hold spray. They can be used for spraying closets, rooms, 
etc... . although they will show some deposit of material 
on highly polished surfaces, or on glass. 
The wettable powder is the safest and the most desirable 
‘form to use for proofing dairy buildings, milk rooms, 
stables and other farm out-buildings against flies. It 
should be applied according to the directions on the pack- 
age and will give excellent satisfaction and protection 
against flies for long periods of time if so used.
