Article and method for enclosing aperture in house siding to prevent or discourage entry by small animals and insects

An enclosing cap for a siding corner channel comprising:

• a horizontally disposed bottom plate having a shape that includes at least one right angle connecting two adjacent straight edges;
• a first pair of exterior vertical side walls protruding at right angles to the bottom plate along the adjacent straight edges and connected at a right angle to one another;
• a second pair of interior vertical side walls protruding from the bottom plate and positioned interior and generally parallel to the first pair of exterior vertical side walls so as to pinch the siding corner channel between the pairs of vertical walls;
• wherein the second pair of interior vertical side walls are oriented each at a slight angle toward the first pair of exterior vertical side walls so as to increase the pinch force on the siding corner channel;
• wherein the second pair of interior vertical side walls are shaped with an elongated portion along lateral edges of the second pair of interior vertical side walls extending upward away from the bottom plate so as to create an area of increased pinch force on the siding corner channel between the interior and exterior vertical side walls;
• wherein the first pair of exterior vertical side walls extend down beyond the bottom plate;
• further comprising at least one small hole in the bottom plate to allow drainage;
• and
• wherein the cap comprises plastic.
