Hello,
So, you want to start breeding crickets? Sounds like everyone else is trying to talk you out of it??? Anyways, I understand that you are spending too much money on shipping, and breeding your own can be both $ rewarding and fun. Here is a basic set up of what you will need. First you will need breeders. Since you are already ordering from someone, order 500 adults and 500 1/2 grown. Put your adults in 1 cage and the 1/2 grown in another. As far as what we do for breeders, we use a plastic storage tub. The sides are smooth, so there is no need for a top, they can't climb out. You can get the tubs from Walmart for $10. I do not use any substrate. At one end of the tub, it is filled with rolls from either paper towels or toilet paper, or egg carton. There is a small tub of food in there. (For food, I use medicated chick feed. You can get it in a 25lb bag for about $4 from a feed store.) As far as water, I use an automatic chicken waterer, also from the feed store. You need to put some sponge in there to soak up the water and let the crickets drink without drowning. 500 adults will easily produce 3000 crickets weekly, if they are constantly replenished. This tub will need some heat to induce breeding. I use a small reptile heat pad from petsmart. You can use heat tape if you have it available.
Now you have the breeders set up, you need a nest spot. Using small storage tubs, I take a small plastic tub and fill it about 4 inches with potting soil. I do not use soil from outside, since it can carry parasites, and other insects. Pack the soil down a little, and keep it lightly damp. I usually have a few of these that I keep in rotation. I put the nesting box in with the breeders, and replace it weekly. Put the freshly removed nest box the rearing box. You can use 2 stacks that you get from Wal-Mart. They are made by Sterilite, and they are under $10 each. I put the nesting box in one of the drawers and leave it. It takes eggs 7-10 days to hatch. The racks and the breeders need to be heated. I have a heat pad I got from petsmart attached to the side of the racks. (It sits between them to warm them all at the same time. Each week, you will put a nesting box in each drawer. If it takes a week to hatch out, and you have 6 drawers total, (3 in each stack), you will have 5 drawers of crickets, You should have crickets about 1-4 weeks old in varying cages. If they are the right size to feed in 2 weeks, then use the other drawers to raise your replacement breeders. Once your crickets are too old to feed to your baby beardies, throw the rest of them back in with the breeders to replace the dead ones. You should average throwing back about 50 a week. That is saying you can afford to lose 10% of your breeders each week. This is basically the set up we use for our pinheads, (scaled down). The best thing is, when you sell all the babies, you can stop production. Once you know your female is gravid, you can start your colony again. You can also duplicate this over again if you need more. If you are needing to raise them to a larger size, 1/2 grown or more, you will need to use bigger tubs. These tubs are just high enough that the 1-3 or 4 week ones will not get out, for the most part. All in all, you are looking at $20 in racks, $10 for the breeder tub, the price of top soil, a heat pad, and your original breeders. It can be done for under $60, and you will have all the crickets you need. Good luck. Sorry for the super long post
