A injection plug assembly for insertion internally into a walled structure to permit safe access to and wide distribution of a fluid, liquid or powder spray into that walled structure. The assembly comprises an elongated outer sleeve arranged to pinch any thickness wall structure and an elongated delivery bolt arranged to be received through the outer sleeve. The elongated bolt has a radially directed fluid distribution channel therein.
This is a continuation in part of my co-pending U.S. patent application Ser. No. 10/661,441, filed 15 Sep. 2003, and incorporated herein by reference in its entirety.
A pesticide injection system for exterminating insects is provided. The pesticide injection system comprises an applicator and a plug frictionally engagable with a wall. The applicator includes a pliable bottle for receiving a powder pesticide and a nozzle for injecting a powder pesticide into a blind space behind a wall suspected of harboring insects without the powder pesticide contacting the insulation. The plug has a check valve to prevent back flow and a door with a door seal to prevent the powder pesticide from spilling into a living space during use. The nozzle has a sleeve biased in a closed position by a sleeve spring for cooperatively exposing a port on the nozzle with an interlocking collar for rotatably engaging a guide on the collar and a tang on the nozzle with a flange on the plug.
