Recently I noticed these little black specks on my tile floor and then I noticed that they moved when swept up. Called Massey and the guy asked me if I had any bird seed around and I didn't. He proceeded to open cabinet doors, look in my pantry and then went to the garage where he found a closed plastic bin with, you guessed it, bird seed. He threw it away and left. Said nothing more needed to be done. Haven't found one since.
