Preventing Wildlife Entry through Ridge Vents

Ordinarily animals enter ridge vents when the end caps fall off. Although the picture to the above left isn't clear, you can see that a nail head shows there is a small gap at the base of this ridge vent end cap.
However the photo below, shows that even when the gap is secure, a gap can still exist that is large enough to permit the entry of mice.
Animals that typically enter through ridge vents include:
- red squirrels
- flying squirrels
- bats
- mice
Secure open ridge vent ends by employing exterior caulk coupled with hardware cloth, copper stuff-it,
or Xcluder™ material to add rigidity to the material.

Although copper stuff-it (left image) can be gnawed through by rodents, it is
more flexible than the stainless steel Xcluder™. Whichever product you
choose, both have won't rust as steel wool will.
