Prepare your trap. Collect breadcrumbs and sugar along with a sheet of newspaper. At dusk, go to your chosen location and sprinkle the breadcrumbs onto the ground. Top that off with sprinkled sugar. Unfold the newspaper and place it on top of the breadcrumb mixture.
Leave and come back the following morning. It is important to check your trap while it is still early, probably at sunrise. Carefully lift the newspaper. Underneath you will find wild crickets. Use the butterfly net, or paper towel tube, to catch them. If you are quick, you can use your hands.
