I have always herd that but never tried it. Thanks for posting.You will need the following:
One slice of white bread, (because crickets dont eat whole wheat)
A pinch of granulated sugar
Spray bottle of water
Spritz a little water on bread, sprinkle with sugar, and put it outside at night where you believe the crickets are near. Tent the newspaper over the top of it. Get up early in the morning to check it, if it gets too hot they will bail.
If you buy your crickets they will actually stay alive in the cage for months. Most people dont realize it, but if you feed them (sugar bread) and water them (we used a bottle cap for a water bowl) and keep them in the shade; you can turn scrawny crickets into studs in a few days.
Have fun. I cant believe no one else has posted a cricket catching recipe....
