Feeding your beetles with jelly is a lot more convenient compared to feeding them with fruits. The jelly lasts longer and does not grow molds as easy compared to fruits. If you can’t find beetle jelly in the pet stores, try out this recipe.


  • Agar – 0.1 oz (3 g)
  • Banana – 1 medium, mashed
  • Brown sugar – 2 oz (~56 g)
  • Clean water
  • Protein powder – 2 teaspoon (optional)
  • Potassium sorbate – 1 pinch (optional)


  1. Boil 12 oz (350 mL) of water and bring it to simmer.
  2. Prepare 4 oz (120 mL) of protein shake. Mix it with the banana mash and blend (optional)
  3. Put in the agar, brown sugar, and potassium sorbate (optional). Stir from time to time until they melt. Turn off the stove.
  4. Pour the protein shake and mashed banana into the jelly mixture. If you choose not to use protein, just add same amount of water.
  5. Stir the jelly mixture and pour it into containers that you intend to keep the jelly
  6. Let your jelly set in fridge

Depending on the brand of agar that you use, you may need to adjust the amount of agar so that the jelly is not too hard.

Potassium sorbate is a preservative to keep your jelly last longer. Without it, the jelly last 1-2 days in the open air.
