Corner Post Protection System

The Problem

Corner posts on a home are the place where the siding from adjoining walls comes together on a home.  While the sub-siding can prevent critters from getting under the siding, the corner posts tend to be left open.  This leaves the perfect entrance to your home for mice, rats, chipmunks, and insects.  Once they discover this pathway, these critters can cause expensive damage to wiring, siding, insulation, and more.

The Solution

Kritter Caps are designed to fit inside most corner posts on vinyl sided homes. Once cut to size, they are easily placed inside the post to prevent any critters from getting in.
