Hi Tim,
a) Fly-swatters?
b) Keep Model A windows rolled up?
c) Park Model A in total darkness?; also,
d) Vintage Cure Before Moth Ball Use: Ever hear of a cedar closet or cedar chest.
e) Research internet for cedar to combat moths.
f} Buy an aromatic cedar plank, (maybe Ebay), hand plane to make shavings, place in (2) separate Zip-Lock bags, punch a dozen holes in each & change out once a year.
g) If all of the above fails, moth balls work well for moths, mice & rats.
