A device for injecting a pesticide from an exposed area to a concealed area behind a wall is disclosed. The device includes a plug which is permanently secured to an opening in the wall. A spray tube extends through the plug from the exposed area into the concealed area. A hose is removably connectable at one end to the spray tube from the exposed area. The hose is connectable at an opposite end to the outlet of a remote pesticide container, thus allowing a remote pesticide container to be used to spray pesticide into the concealed area.
