Thanks again guys for the help. I have good news
. I did a thorough search of the stuff in the side room of the garage and those arrows are the only thing I see with mold starting to grow on them. Maybe they got it from being in a storage unit for a year. But under the circumstances of me having all the moldy stuff in that room for 3-4 months I just assumed it came from there. I cleaned up the arrows and will keep some air flowing and hopefully the mold will stay away!
