Dubias can be stored in a plastic tub, I used a cheap clear plastic tub from Wilkinson and drilled some holes along the sides and through the lid so well ventilated. Put some egg crates flat along the bottom as they like to hide. They can't climb so won't escape.
Locusts I have a cricket keeper which bought from pet store, it's essential just a clear plastic tub. Again put some egg boxes so they have somewhere to hide and climb on. They can climb so make sure whatever you use is secure lid. Locusts are from a warm climate so like the heat and if you feeding them need to be warm or the food rots in stomach.
