@diane Your welcome. Good, yes potatoes are really great and work for both food and water. Just use up what Fluker food/water you have left, no since wasting it, or gift to a friend with a reptile.
The dog treats you make sound fine and I can see why the crickets love them, I bet my dog would too.
Just so you know crickets aren't really picky on food, just as long as it is ground or tiny in pieces they can eat it easily you'll be fine. Sounds like your a hands-on crafty person so your love the hobby, always something that can be made/modified/etc for many uses.
No problem, your welcome and I'm always more than happy to help. Ah a mantis favorite for sure a moth, so high in fat they are like junk food for them. The fly is a staple feeder for most keepers (easy to catch even with a cheap "kids" butterfly net or
trapped outside) and buying pupae avoids the hassle of crickets or cockroaches. Glad to hear you give your mantis a varied diet, it is a great way to ensure your mantis nutrition needs are met, is happy, and you can find out what feeders it prefers.
As I haven't bother to show my cricket setup forever, and some things are bound to be unclear for you, I just took some photos of my adult cricket tank. It is a large plastic bin I got after Christmas for $8 and holds thousands of crickets easy (35" long x 19" wide x 13" tall). Any size container with airflow is fine for crickets, depending on how many you keep.
The bin has a large aluminum mesh opening for air (as they can chew threw plastic/fiberglass mesh). I have the bin sides covered in cardboard below the lid to keep the heat/light that sits on top from blinding the rest of my bugroom - it also helps keep heat in as well.
Inside the bin you can see two of my 1 quart chicken waterers (the
bowl base and
water jar) in my bin with
plastic craft mesh in the bowl area. I also put cotton balls below the mesh to keep any small crickets from drowning between the gap, and keep the mesh at the proper height (water barely above the mesh, and they can drink through the mesh, but stops drowning). As the bin is slippery plastic I add a thin layer of the chicken egg layer crumbles or oats to give them traction to move around properly. I keep a
reptile mealworm cup (as I have several) in there as feeding bowl, but any small cup works, and crickets are messy with it anyway. Then of course cardboard egg crates, cardboard tubes, etc for them to live and hide in.
The small deli cup full of moist dirt, with a cut lid holding a aluminum mesh cover is the crickets egg-laying container. It keeps the crickets from digging in the dirt, and the new pinhead crickets hatch and escape easily. Although I tend to swap out the container before they hatch to another bin, as adult crickets will eat the small crickets. The crickets lay some eggs in the waterers, but nearly 90%+ of the eggs are in the dirt cup.
As you can guess crickets can be as simple as a potato in a small tote to whatever you want. I got mine setup like I do as they are self-sustaining now (if not too many crickets at times), so I have crickets from pinhead to adult always around for any pet feeder size.
