seen in fig2 there is no horizontal surface through the housing along the base thereof which does not contain exposed glue 14 the height of the grooves can be greater than the thickness of the glue board or greater than the thickness of the glue supporting base of the glue board fig3 4 and 5 depict exemplary dimensions for an embodiment in accordance with fig1 these dimensions can be varied desirably the width dimension is great enough to receive a commercially available glue board without the need for cutting or folding the glue board in addition desirably the height is low enough to minimize the possibility of birds bats and flying pests traveling through the trap without engaging the glue board an exemplary desirable height b is two inches from the outer surface of base portion 22 to the outer surface of top portion 24 an exemplary groove or slot 50 52 is approximately 3 16 u2033 in width w in fig5 and 6 and u215b u2033 in height h in fig5 and 6 and can run the entire length of the housing or tube the housing 20 of fig1 can be manufactured by any convenient process although the housing can be made of other materials such as wood or metal or combinations thereof an exemplary housing is a one piece unitary monolithic housing that is molded or extruded of a desirable polymer material such as pvc if extruded for example using a metal die individual traps can be cut to length by cutting off lengthwise extending sections of the extrusion in.
