Get some tubes of Fly Paper. The kind I get is just strips with glue, no chemicals or pesticides. Comes in what I call Tubes, you pull the end off then slowly turn and unroll it into a long strip. Buy alot of them, they are cheap. Obviously don't put them in the cage or anywhere that your pets can reach them. They really do work! I use them all the time in my basement. Not only for flys, which aren't too bad, but mostly for those annoying moths that once you get it's hard to get rid of. I'd be driven out of my house if it weren't for the fly strips catching so many! Good Luck!
