Why didn’t Nazi use DDT during WWII for typhus?

DDT was first synthesized in 1874 by German chemist Othmar Zeidler. DDT was not used as an insecticide until 1939. In 1939 Swiss scientist Paul Hermann Muller discovered the insect-killing properties of DDT.
Why Germans didn't use DDT? Was there no DDT available in Germany? Why they preferred Zyklon B?

However, I.G. Farben couldn’t produce more DDT because they did not have enough Chloral, which is necessary to produce DDT.


I'm still not sure if the Germans would have used DDT for typhus and lice though since they did still produce Zyklon B.

DDT must be used in powder or in solution in organic solvents, fats, or oils. Thus, in order to treat the clothes or mattress DDT is not very practical for an extended application in comparison with the use of a HCN gas which doesn't leave any traces after a strong ventilation.
Moreover, in opposite to DDT the use of HCN gas doesn't require a lot of manpower, the effect is reached by just leaving Zyklon pellets into a room.
However, DDT powder was very useful for treatments by direct application on the human bodies.
Considering the reality of the camps, the use of HCN was the more valuable solution to treat rooms and inmates' effects. However, the fight against lice and vermin would have been considerably improved by the application of DDT powder on the bodies of the prisoners.
