Claims8
In a crawling insect trap comprising an upper surface, a bottom surface and side walls, having an opening in said upper surface leading to the interior of said crawling insect trap, a layer of glue within said trap covering at least a portion of said bottom surface, and an inwardly sloping ramp, having an angle of inclination, as measured from a plane parallel to said bottom surface, of from about 5.degree. to 10.degree., coterminous with an inwardly sloping decline having a final angle of elevation, as measured from a plane parallel to said bottom surface, of from 10.degree. to 90.degree., covered with at least a particulate material, which will come loose when walked upon by a crawling insect causing the insect to fall through said opening into said trap and to be held fast therein by said layer of glue.
In an ant trap comprising an upper surface, a bottom surface and side walls, having an opening in said upper surface leading to the interior of said crawling insect trap, a layer of glue within said trap covering at least a portion of said bottom surface, and an inwardly sloping ramp, having an angle of elevation, as measured from a plane parallel to said bottom surface, of from about 5.degree. to 10.degree., coterminous with an inwardly sloping decline with a final angle of elevation, as measured from a plane parallel to said bottom surface, of from 10.degree. to 90.degree., covered with at least particulate tetrafluoroethylene resin or a ground pyrophyllite-aluminum silicate, which will come loose when walked upon by an ant causing the ant to fall through said opening into said trap and to be held fast therein by said layer of glue.
