ABSTRACT:
Fluid, such as pesticide or the like, can be injected into a wall through each of a plurality of fluid-injection plugs that are mounted on the wall. Each plug includes a blind-ended bore and a fluid passage port that fluidically connects the blind-ended bore to the outside of the plug. A bore-closing plug is releasably mounted on each plug and is removed to provide access to the blind-ended bore and is then replaced to close the plug. Fluid, including air-entrained powdered substances, can be injected into the wall by connecting a suitable supply of the fluid to the blind-ended bore after the plug has been removed and forcing the fluid into the blind-ended bore. The fluid will then pass through the fluid passage port out of the bore and thus be injected into the wall.
