Apparatus and method for attracting and trapping insects

An apparatus for attracting and trapping insects comprising:

• (a) a frame having spaced-apart supply and take-up supports having a trapping area therebetween;
• (b) an elongated section of flexible trapping material extending between said supply and take-up supports in said trapping area, said trapping material having a coating of a sticky substance thereon, said trapping material having a generally tubular cross-section and being in a rolled condition when on said supports;
• (c) expander means within the cross-section of said trapping material in said trapping area maintaining said material in a generally tubular condition substantially throughout the length of said trapping area;
• and
• (d) drive means for advancing material between said supports such that flattened previously-unexposed lengths of trapping material are advanced from said supply support to said trapping area and expanded and previously-expanded lengths of trapping material are drawn onto said take-up support in a rolled condition.
