DDT was banned decades ago Do you make your own? {:-))

DDT is still used in large areas of the world to control malaria.

Unfortunately you are right. I wonder whether the number of people
killed by the DDT is more oor less than the number which would have
been killed by malaria if it had not been used.
However, the question is rather academic, since is is banned in the
UK.

Actually not. DDT is surprisingly well tolerated by mammals, but it is
long lived and gets concentrated in fatty tissue. It is exceedingly bad
for birds especially raptors. It is a tricky problem when malaria is so
deadly.

Most of the expensive new replacements for malaria control are more
acutely toxic to humans than DDT ever was.
