What to do about puppy chewing?

I am fostering a 2 month old border collie mix. Lately she has gotten into the habit of chewing EVERYTHING. I know as a puppy she is going to chew, but it is literally driving my family and I insane. We bought rawhide bones for her and she has other toys to chew on. She is choosing wires though and I don't know why? We have been keeping things away from her, but she seems to find something else she's not suppose to have. Any ideas on what to do? We only have her for 2 weeks, but that seems a long ways away.
