A disposable container for the mass-rearing of insects can include a first layer, a mixture, and a second layer. The first layer can be molded to form a cavity and define an opening to allow the mixture to be positioned in the cavity. A quantity of the mixture can be positioned in the cavity and comprise insect larvae and food for the insect larvae. The second layer can be positioned over the opening and coupled to the first layer to seal the opening. The first layer or the second layer can include a disposable material and the second layer can couple to the first layer to form a disposable container.
