On April 26, 1910 the Insecticide Act of 1910 was passed being the first pesticide legislation enacted.  “An Act for preventing the manufacture, sale, or transportation of adulterated or misbranded Paris greens, lead arsenates, and other insecticides, and also fungicides, and for regulating traffic therein, and for other purposes”.

“With the Insecticide Act of 1910, mosquito spraying [with kerosene] became not only standardized, but also relatively safe.” [2]
