winterizing question Low point drains open or closed

What kind of bugs, mud daubers or any other insects, present a danger when there are freezing temps enough to drain or add antifreeze?

Probably no bugs if you winterize when temps are low.

But for myself not going to use RV till spring when bugs might be out and about. Or what about someone that has to store their RV for longer length of time. Personally after asking question...I thought that mold near any openings would play a roll more so than bugs. But every place is different. With me mice getting inside my RV biggest worry. Dang they can fit into the smallest places and make a mess.
