On this day in 1941, G.G. Wittwer et al. were granted the patent for Ant Trap. U.S. Patent No. 2,242,099.

One of the objects of this invention is to provide an ant trap which is so constructed that it will stand a tremendous amount of rough handling or abuse, without the parts becoming displaced or disassembled, so that after the trap has  been assembled with the insect bait or poison within the trap and the same hermetically sealed during the assemble operation, no material will escape from the trap during packing shipping, storage or handling.  Furthermore, the trap is so constructed that children cannot get into it, and neither can animals, such as dogs and cats.  Consequently the chances of any person or animal being poisoned by the material are substantially nil.
