We have had a HUGE problem with house flies this year. I found this INSIDE bug attractor that you plug into an outlet. It does an amazing job. Link to refill cards and bulbs below as well.

I am updating our extra room in the basement/guest room (soon to be my office) and I found inexpensive comforter set for the bed we have in there. There is a variety of colors available.
These are amazing for removing hard water stains.
