• I feed my hornworms Repashy SuperHorn. They are voracious eaters. They grow very fast, and if they are too big can be a choking hazard to your gecko...my experience.
• Mealworms, superworms, crickets, dubia roaches - all of these bugs eat chopped carrots, green beans, papayas, and oranges DAILY. Repashy also has something called Bug Burger that can be used as a DAILY food (if you want to go that route). Anyway, 24-48 hours before I feed these bugs to my gecko, I remove a few, and place them in another smaller container with Repashy SuperLoad (gutload).
It's that easy. No spreadsheet. Just keep your bug containers clean. I clean mine out every 3 days, but I don't stock huge amounts of bugs. You have to keep the containers clean because the veggies/fruits will get moldy (it only takes about 3 days), and you don't want your bugs eating mold, plus the bugs poop alot. Healthy food = healthy gecko.
Dubia roaches can be kept in a small plastic kitchen container. I buy 12-20 at a time from a local reptile dealer. Just make sure they have something to crawl on in the container (a piece of egg carton). Let your parents know that Dubia roaches are NOT ****roaches, so they aren't going to invade your home...and your Mom isn't going to have to call an exterminator, LOL. Dubia roaches are tropical bugs and they aren't going to survive well in your house on their own.
