Living in the South humidity is an issue always. Especially in the fall and Spring when it's too cool to run the A/C and the weather outside is still humid. In the winter it's usually dry enough outside that humidity is not an issue. Heat pumps do not dehumidify like a lot of other heat sources, and heat pumps are prevalent in the South.
I use these. Turbocharged silica gel packs. You get 280g of silica for $1.
