She distributed the resin quickly using her jaws. I don’t know where she found the resin but after 5-10 minutes she would return with a new batch.

I don’t know where she found the resin, but she made exactly one more flight that took ±27 minutes to collect enough resin to close up the entrance.
She distributes the sticky substance quickly with her jaws over the remaining opening.

After the entrance was entirely covered with resin she started sticking small pieces of wood in it without covering it completely when she finished.
