Hang the Pheromate xtra time block in the Trap and install it in the farm. There is a dual locking system in the Trap so that once it locked, it can’t open easily. Pass all the half circle lock from relevant rectangular gap, and form the Rectangular Trap as shown in picture. Pass the thread from the hole made in the upper lock and hang the block in such a way that block will hang in front of triangle window. So that fruit fly can easily touch the block. There is a transparent part at the bottom to observe the collected flies. The colour of Trap will also help to attract the flies. Colour is heat resistant so that it will remain longer.
