The two parasites you would have to worry about are wax moths and small hive beetle (if they’re that far north). If you have lots of bees coming and going from a hive, the odds are the wax moths are under control. I don’t have SHB here, so I don’t know about them. I only worry about wax moths in nucs or weak hives.
You could check for varorra mites by uncapping some drone cells, looking for deformed wings on the bees, and counting mites drops under a screened bottom board. If this is a first year hive, the mites probably haven’t out populated the bees yet and you are probably OK. If you have a large mite count then you could split the hive to bring the mites down, or do some chemical treatment on which there are lots of threads on this forum.
