Some of my items are meltable. Is there any way to exclude certain US states more in the south?

Outside of using dry ice, meltable items can still risk arriving melted even with all preventable measures.

No, you cannot exclude states with the exception of Alaska/Hawaii.

Some marketplaces, like The River, do not allow sellers to sell meltable items for fixed months of the year. It gets hot in a UPS or USPS truck in places you might not think of.

You should probably not have active listings on Ebay for meltable items during late spring and summer.
