A bug killing gun includes a compressed gas source fluidly connected to a chamber connected to a barrel. A compressed gas release mechanism is connected to the compressed gas source. A projectile storage magazine stores particulate projectiles and is located adjacent the chamber. A projectile loading mechanism moves the projectiles into the chamber from the magazine. A cocking mechanism is mechanically connected to the compressed gas source, the compressed gas release mechanism, and the projectile loading mechanism. A stock houses and supports the compressed gas source, the compressed gas release mechanism, the barrel, the chamber, the projectile storage magazine, the cocking mechanism and the projectile loading mechanism. When the gun is cocked, the projectile loading mechanism loads a predetermined quantity of the particulate projectiles into the chamber. When the compressed gas release mechanism is activated the projectiles are ejected from the chamber into the barrel and expelled from the gun.
