Bunnies are pretty easily litterbox-trained. Why not move the bunny indoors? As for the earwigs, I would put Floppsey indoors (confine her to the kitchen or bathroom, at first, then empty, clean and disinfect the food dishes, the water dishes, and the whole cage, if you are going to keep the bunny cage inside. Then you don't have to worry about bugs! As for the food container, I would just throw away whatever food is left in it, and clean and disinfect that quite thoroughly.
