If you keep or breed insects that climb such as crickets or roaches, you know that you will need a smooth surface that they can not climb around the inside of their enclosure about 4 inches from the top. This is the tape that we use to keep them in. You get 45 Yards on a Roll! This is also the same tape we use to tape all of our packages that we ship on a daily basis. It's been tested time and time again. We know it works well!
