Hi. Spend 0 because I have a dubia roach colony. I did spend 200.00 to start it but that was a year ago. Definitely worth it. I do feed hornworms once in a while just to give them variety maybe 5x a year.
I was spending around $50 every 2 weeks for dubias for Harley when she was little but I started my own dubia colony so now I just spend around $20 every 2 weeks since she's in mini brumation and at the moment all she wants to eat is collard greens and dubias and a little mango here and there.
I spent about $250.00 to get my Dubia colony started.
Now, about a year later, I'm selling all the extras that my scale-babies
don't eat up to a few local people and making about $100.00 a month
profit (after expenses to maintain the colony and such).
I also spend about $5.00 a week for greens/veggies as well.
