Killing mosquitoes for me and for you.

Their labors resulted in great success.
Of every one hundred mosquitoes, there were ninety-nine less.

But they were mocked and they were scorned,
Their heads with criticism were adorned.

This answer is simple as numbers can be.
And the calculations reveal for all to see.

That if ninety-nine percent of one billion are slain.
Ten million of the devils still remain.                            (unknown)
