The invention consists of a related series of simple device embodiments used for the spot control of insect pests. Each of the invention embodiments uses the relatively common, non-toxic insect control substances, including a non-drying adhesive and/or diatomaceous earth and stabilizes them for convenient, effective application by affixing them to a disposable media carrier, such as paper, vinyl, thin foam, cellophane, etc. The first embodiment of the invention has the form of a double sided tape with a standard contact adhesive on one side and a tacky, non-drying adhesive on the other side. The non-drying adhesive acts as an effective insect barrier when the tape is applied around a perimeter to restrict crawling insect passage. A refinement of the double sided tape invention embodiment has the outside facing non-drying adhesive applied in combination with an adjacent or interspersed pattern of applied diatomaceous earth. The combination of the tacky, non-drying adhesive and diatomaceous earth work together to effectively kill crawling insects. Another embodiment of the invention uses a diatomaceous earth impregnated media that is cellulose based and which may be baited with sugar or other insect attracting substance(s). This cellulose based media is made in the form of a decal applique or stand alone form that can be applied to a plant leaf or affixed to some other plant or garden structure. When insects eat the leaf where the decal is affixed or the stand alone form they ingest the diatomaceous earth which effectively kills them by shredding their gut.
