timber in the roof?

Rapid drying of green lumber can lead to excess warping, checking, etc. Generally speaking, attic space is typically used to finish off lumber that has allready been air dried somewhere else so the remaining moisture can be brought down that last 6-12%.

Attics are typically too dry to support mold. If you get a mold problem in the wood then you’ve got some other roof problems to take care of.

Different species of termites behave differently. The species I deal with won’t suddenly appear high up in an attic simply because you put some wood (food) up there. They typically come out of the ground and use a pathway of wood like a wall stud that they eat as they go. But you’re down under and things fall up there and you have some species of termites that definately could behave differently.

Since you’re dealing with small quantities of wood, I would find a way to dry them down some in another area before moving them to the attic.
