PT Alpine Pressurized Fly Bait is only labeled to treat for House Flies, Filth Flies, Lesser House Flies, Flesh Flies and Small Fruit or Vinegar Flies. Depending on where you need to bait, you might be able to use EndZone Insecticide Sticker. You can take a look at this helpful article on How to Get Rid of Blow Flies which will not only tell you where to look for a source, but also how to treat and what to use.
