What other kinds of pets do you have at home? Because you can feed your buggies to all kinds of other animals too
I have rats, ASF rats and Hedgehogs that will all eat bugs
I keep fish, and my fish all eat insects

Feeders can be frozen for later use

Grind them up and turn into a paste, you can add a binding agent (gelatin, or agar) and add other ingredients to it and make pet food

You can post an add on Kijiji or Craig's List, and sell or give away the extra ones. Chances are there are some herpers out there that wouldn't mind free or cheap feeders

Are there any reptile/fish clubs in your area? Maybe someone there might want them?

Do you have any friends that keep any herps?

Or, buy more frogs?
