How to care for Mealworms

Once you bring your worms home, please remove the fabric cover from the lid or carefully empty the worms out of the fabric bags. Emptying the bag over a bowl or tray will help prevent escapees. Be sure to get all of the worms off of the paper and inside of the bags. Place the worms in Optimal Worm Food & Bedding, wheat bran or oatmeal. Make sure to give the worms or beetles moisture in the form of fresh vegetables (sliced carrots or potatoes) immediately. They will be very thirsty from their travels. 

Store your worms in a container with air holes; the worms cannot climb smooth plastic. Keep your mealworms in a fridge; temperatures of 3 to 7°C are ideal. At lower temperatures, the mealworms may die, and at higher temperatures, the mealworms will become more active, need feed and may begin to pupate. 

If you plan to use up your mealworms within 3 weeks, no extra care is required. 

For more than 3 weeks, follow these steps once a week:

  1. Remove your mealworms from the fridge.
  2. Place a food source in with the mealworms. We use thinly cut slices of squash, potato, or carrot. Let the mealworms eat for 3 hours.
  3. Remove any and all remaining pieces of food.
  4. If no bedding remains, add approximately 1/4 cup of Optimal Worm Food & Bedding or wheat bran for every 1000 mealworms.
  5. Place mealworms back into the fridge.
