Varroa mite treatment late fall

Hey all. First year beek here located in Raleigh,NC. I did another hive check today including an alcohol wash. I did one in the summer and only found a single mite. Today th mite count was way up if I had to guess maybe 30-40 mites in about 300 bees if I was guessing. So I used a website someone recommended called honeybeehealthcoalition and they offer some cool tools like telling me which treatment is ideal for me. So I got two brood boxes no super on with brood in the hive so I went with apiguard. Temps are supposed to be above 60 during the day with a low of 40 at nights. Just wanted to see if this is the right treatment for this time of year and if yall have had good experiences with it, thanks!
