Place the egg deposition container in a plastic shoebox with lid. You may also want to add tape near the brim of the sweater box to prevent the crickets from crawling to far up. Add the toilet paper core. The eggs will hatch in 10-12 days. Use the toilet paper core to tap the crickets into the frog's tank.
Crickets love to congregate in dark areas, so the core come in handy for transferring crickets.
For daily maintenance, make sure to get rid of dead crickets because they can spread infection. Add food periodically and make sure that they have a source of moisture. Vegetable scraps provide them with enough moisture. There's this new kind of cricket food that looks like gelatinous cubes that helps to feed, water, and gut-load at the same time. If you have roses in your backyard, you've probably have had experiences with these bugs.
