Thread: Type of Passive Crawl Space Vent to prevent rodent entrance

My old crawl space vents have some areas (around the edge) where rodents have chewed through during the winter. What type/brand of vents (i.e. passive open/close) could I replace them with that would prevent this occuring in the future?

There are few things a rodent cannot gnaw through.
Just repair or replace.
You might consider calling an exterminator to get rid of them.

Google 'rat proof foundation vent'.
