A method and apparatus for dispensing selected amounts of insecticide through a needle into building structure void spaces. The apparatus includes a needle tube with elongated opening and an applicator for pneumatically forcing metered amounts of insecticide through the needle tube for release within the void space. The needle may be non-destructively inserted through various forms of wall panel members without necessitating remedial measures.

A method for application of dust insecticide within building structure void spaces, comprising: inserting a needle having an axial bore and a slot formed near the pointed end through a wall structure into a void space by manual force whereby the needle may be removed to expose only a barely visible puncture mark; forcing a charge of dust insecticide under air pressure through said axial bore for explusion in said void space; and repeating the steps of inserting the needle and forcing a charge of dust insecticide a multiple of times at selected intervals along said void space, whereby the total void space is effectively treated. Apparatus for application of insecticide through paneling into building structure void spaces, comprising: a container including a selected insecticide; a needle having a hollow bore for effectively non-destructive insertion through said paneling into a void space, said needle including an elongated metal member defining an axial bore that extends from a cap end to proximate a pointed end and having at least one radially aligned, arcuately formed slot communicating with said bore proximate the pointed end; applicator means receiving a selected amount of insecticide from said container and being in communication with said needle bore; and a source of air pressure connected to said applicator means to expel said selected amount of insecticide through said needle bore into the void space.
