Not sure about indoor, but I use Ladybugs outdoors, to control pest's. They have always worked for me and when they leave it's because there's no more food (bugs) for them. You can buy them at a garden supply or nurursey.
yeah theyll work just fine,only one problem,,,,theyll fly into your lights...a little ladybug and a 200 degree hot light will make quiet the mess........just have a lot of paper towels handy........ not a good idea fellow...
