Step 1. Using a air pump and the inflation needles included you will need to inflate the Gnat Ball to 12 inches.
Step 2. Using fishing line hang the ball(from the tab) to a post or tree limb about 4-5 feet off the ground in the sunny place next to a shaded area (the black ball will produce heat that the flies are attracted to)
Step 3. Then apply the tangle foot thoroughly all over the Gnat Ball. NOW YOU HAVE A GIANT FLY TRAP!
