PISTOL SQUIRTS LIQUID THAT KILLS FLIES (Oct, 1931)

PISTOL SQUIRTS LIQUID THAT KILLS FLIES
A toy-like pistol, shooting liquid insecticide, is designed as a fly exterminator. A fly that is hit, it is said, immediately falls to the floor and dies. Mosquitoes and other insects also succumb to the liquid, which is said not to harm walls or draperies. The gun is cocked by squeezing the handle, and discharges a concentrated spray when the easily operating trigger is pressed.
