A large fly trap apparatus designed for use around livestock and other outdoor areas to attract and trap flies without bait. The apparatus includes a base and a cylindrical canopy having a plurality of conical feeder tubes for entrance into a trap chamber. The canopy is formed from a plurality of support frames covered by a mesh covering. The feeder tubes allow flies to land on the outside of the mesh cover and crawl through the funnel-shaped feeder tubes into the trap chamber, where they become trapped.
