Exotic Nutrition's Mealworm Keeper is a bedding and food source for mealworms and other live insects. Providing your insects with a high-quality food source will ensure they are getting the nutrition necessary to stay alive and healthy. To gut load, mix a high-protein food source like Exotic Nutrition's Mealworm Chow with your Mealworm Keeper before feeding. 

  • We recommend 1/2 lb Mealworm Keeper per 1000 Mealworms (med) or 1 lb per 1000 Giant Mealworms
  • Bedding and food source for mealworm and other live insects
  • Ensure insects are getting the nutrition necessary to stay alive and healthy
  • Combine with Exotic Nutrition's Mealworm Chow for optimal nutrition
  • Net Weight: 1 pound / 16 ounces

Feeding Instructions: Keep live mealworms in a well-ventilated container. Evenly distribute Mealworm Keeper in the container using approximately 1 cup for every 250 live mealworms to serve as a primary source of food and bedding. Along with Mealworm Keeper, offer raw potatoes or raw carrots to add moisture to the diet. Exotic Nutrition’s Thirsty Cricket is an alternative drown-free water source.

Storing live mealworms in a refrigerator at 45-50 degrees fahrenheit will cause them to go into a dormancy for up to 10 weeks. Remove mealworms from the refrigerator once per week to wake them from their dormant state to eat. Allow mealworms to feed for 24 hours at room temperature, then remove any uneaten raw food and replace bedding before placing them back into the refrigerator for longer storage.

Feeder insects may lose some nutritional value after staying dormant for multiple weeks. It is recommended that you gut load insects 1-2 days prior to feeding so they provide maximum nutrition. Gut loading is the process of feeding insects a diet high in vital nutrients prior to feeding those insects to other animals. To gut load, mix a high-protein food source like Exotic Nutrition's Mealworm Chow with your Mealworm Keeper before feeding. Additionally, you can sprinkle a multivitamin or calcium supplement on insects before feeding to help prevent calcium deficiencies.

It’s great but it needs to come in a larger bag - Carina E.

Great for bedding and keeping mealworms alive longer -Tina M.

Good service and good worms. They mark the boxes so delivery people know there are live animals and aren't put in the mailbox. I don't think you will be disappointed! - Linda J.

I’ve fished for Kokanee salmon here in Northern New Mexico for years in Eagle Nest Lake and find meal worms to be excellent bait on size 10 treble hooks. The two of us are limited to 10 salmon each day and we harvest 20 every two days between us and smoke them. They average 20” and are definitely worth the effort in such an extraordinary setting! - Gary. L.

I love the Exotic Nutrition brand mealworm keeper. My mealworms and beetles are very happy living there. Very clean, comfortable, and consistency is great. Beetles are hatching eggs like crazy on it. I will order again and again. - Kaori S.

Everything I have received from Exotic Nutrition has been great. My worms came and very few were dead. Quality merchandise and customer service. Janine helped me out great deal when I first got started. Great honest company. -Kevin G.

I have been pleased since I purchased Thirsty Cricket. During a busy week, I killed my entire mealworm population by not checking the carrots. The carrots had molded, which is toxic. I also had to replace the Mealworm Keeper and the Mealworm Chow. I love all three products. I feed the mealworms to the Wild birds, especially Blue Birds, throughout the year. Learning about the Mealworms' life cycle and raising them from worms to Beetles has become an interesting hobby. -Catherine R.

Yet another staple that keeps me coming back to Exotic Nutrition (although, there are MANY products like that). I've had no problems whatsoever with the Mealworm Keeper or the Mealworm Chow - I'm a customer for life. Super fast shipping, great prices, and an awesome selection of products.

seems to work really good at keeping the mealworms alive. You do not have to use as much as the instructions say. When it starts to disappear I add more. -William T.

I received my mealworms quickly and not a single dead one in the batch. I ordered a thousand but will order two thousand this time. My Beardies love them. They are like a candy bar for them. -Janet M.

just what I needed and exactly as described. Thank you. -Mike B.

by John B on January 5, 2019

Excellent product , there were no dead mealworms in the order. The mealworms were fat and juicy to all my pets that eat meal worms. The pellets to feed the mealworms was very fresh. When changing out the meal worm box and adding fresh pellets the mealworms made a mad dash for their food pellets. I am so impressed in the quality and freshness of my order I’ve doubled up on the quantity. I highly recommend - John B.

First attempt at mealworm farm. Appreciate the help.

This is our first time ordering this product, to use as bedding and spreadable food. We put it in the mealworms trays and they seem to enjoy and retain their weight. Good product.
