A liquid insecticide applicator in the form of a trigger pump having a detachable, semirigid, tubular extended nozzle press fit into a recess within a nipple along the discharge end of the pump assembly is provided. When the extended nozzle is engaged to the pump assembly, the applicator is suitable for applying or injecting insecticides such as solutions of containing disodium octaborate tetrahydrate (D.O.T.) into holes or wall voids. When the extended nozzle is disengaged from the pump assembly, the applicator can deliver contents in a spray, suitable for treating larger surfaces, such as large areas of exposed wood. Preferably, the liquid insecticide solution used with the applicator is a 5% to 20% water solution of a DOT mixture comprising disodium octaborate tetrahydrate, colored pigment, and a bittering agent of either sucrose octa-acetate or denatonium benzoate. The applicator may alternatively be used to deliver liquid fertilizer to a plant by injecting the fertilizer below the soil surface, closer to the root structure of the plant.

[ What is claimed is:] [1.]1. A hand-held trigger pump insecticide applicator for applying an insecticide solution into holes, cracks or wall voids, the device comprising:a pump assembly activated with a trigger;a nipple rotatably coupled to the pump assembly and defining a cylindrical recess of approximately 0.085 inch in diameter, the nipple being rotatable to selectively restrict flow;a semirigid tubular extended nozzle approximately 6 inches in length and having an outside diameter of approximately 0.085 inch adapted to press-fit into the cylindrical recess of the nipple; andan unpressurized reservoir that threadedly and detachably engages the pump assembly, wherein the reservoir contains a liquid insecticide comprising a 5% to 20% water solution of a disodium octaborate tetrahydrate mixture, the mixture having comprised, before dissolution in water, at least 95% by weight disodium octaborate tetrahydrate, pigment, and an ingredient selected from the group consisting of sucrose octa-acetate and denatonium benzoate.
