To keep your superworm larvae happy and healthy you should satisfy a brief listing of requirements.
First, you need a dark, escape proof container. Using an aquarium to accommodate your larvae is not really suggested for a number of reasons. There is certainly far too much wasted space in an aquarium. You might think of keeping more Superworms in a deeper substrate to make the most of available height. This can be not a good idea because the thicker the substrate and layer of superworms, the better heat and mess is produced. Additionally, larvae can easily climb the silicone bead running the inside which joins the pieces of glass together.
A shallow rubbermaid container is most effective. You will have to drill really small holes to the container for air circulation. Stay in mind that superworm larvae have quite strong mandibles and if they can have their mouth on an inside edge of your drilled holes they will have little trouble enlarging it.
The next thing to keep your superworms healthy is providing a top quality substrate. You can find normally among two methods employed here. One idea is to provide a consumable substrate which offers both a food source and living environment. Another is to provide a non consumable substrate like wood shavings.
The second method is favorable because superworms often fair better in a moist environment. Superworm larvae need to have a light mist water over their substrate occasionally to help keep humidity levels high. Spraying a consumable substrate like grain or cereal routinely can bring about mold and mites, each of which can destroy a colony.
Water is an important variable in not merely the fitness of your superworms but in addition in breeding them afterwards if you opt to do this. Superworm beetles may not lay eggs without the correct humidity levels. Superworm eggs may die if allowed to dehydrate extensively.
To supply a supply of water to drink a standard method is by using potatoes (cut in two) or carrots. This is an economical solution with the additional benefit of potatoes being easily stored for later use. Another common way of providing a supply of hydration is to purchase food/water cubes which can be made by various pet product companies and sold online or via your local pet store. They may be a handy approach to offer both food and water in just one package with the additional benefit of supplying your insects with vitamins and minerals. Try to find food cubes meant for feeding/hydrating crickets.
Another essential consideration is heat. Superworms unlike mealworms can not survive at low temperatures. Putting superworms in the fridge to keep them for later use like one would do with mealworms can lead to the death of the superworms. Room temperature is fine to keep the larvae, however keep in mind that they will grow faster and breed better if at all dibqgk at higher temperatures (75 degrees and up).
To give your superworms just about anything is going to do. They can be fed on grains, vegetables, carrion, salad mixes, high quality fish flakes, commercial diets, dog food etc.
Keeping superworms successfully is not really hard as long as one follows some elementary guidelines.
So remember, find or buy a dark, escape proof container. Make use of a substrate of wood shavings. Feed them often and vary their diet. Spray their substrate with a very list mist of water routinely. Keep the superworms at a warm temperature. Finally, do not forget to clean their enclosure often.
