Sealing crawl space vents?
I currently run a dehumidifier in my crawl space with most of the vents closed in an attempt to lower the humidity. However, I have 7 vents that I can not close because the wooden deck has them blocked off. So I want to seal them from the crawl space side and am looking for suggestions. Should I cut some rigid foam insulation and mastic in place? Your suggestions are much appreciated.

Yes that will work. We use the foam and then spray foam in place.
Thanks again!
