Sealing holes...
Don't just caulk or use some sort of filler to seal spaces. What made my treatment so expensive was that they used metal wire mesh, same color as my siding, then they went over the mesh with caulk of the same color. The rodents can't gnaw through metal. I was amazed at how they could fit this mesh into the smallest holes. I was told that, what they did, also increased the insulation value of the house greatly.
