How To Raise Mealworms: The Complete Guide

Mealworms can be a great source of protein for pets, livestock, and even humans. They are easy to raise and require minimal maintenance, making them an ideal option for those looking to get into small-scale insect farming. In this guide, we will walk you through the step-by-step process of raising mealworms at home.

1. Setting Up Your Mealworm Farm

The first step in raising mealworms is to set up your farm. You will need a container with a lid, such as a plastic tub or a glass aquarium. Make sure the container has enough space for the mealworms to move around and breathe. You will also need a substrate for the mealworms to live on. Wheat bran or oatmeal are good options.

Once you have your container and substrate, add a layer of it to the bottom of the container. Make sure the substrate is at least 2 inches deep. You can also add some pieces of cardboard or egg cartons for the mealworms to crawl on.

2. Adding Mealworms to Your Farm

Now that you have your farm set up, it's time to add your mealworms. You can purchase mealworms from a pet store or online retailer, or you can start with a small number of wild-caught mealworms.

Place the mealworms on top of the substrate in your container. Make sure they are evenly distributed and not touching each other. Cover the container with a lid to prevent any escapees.

3. Feeding and Watering Your Mealworms

Mealworms are relatively simple to feed and water. They primarily eat grains, including wheat bran, oatmeal, and cornmeal. You can also feed them fruits and vegetables as a treat. Make sure to remove any uneaten food after a few days to prevent mold growth.

As for water, you can provide a shallow dish filled with water crystals or a slice of potato. The mealworms will get all the moisture they need from these sources.

4. Cleaning Your Mealworm Farm

To keep your mealworms healthy, you will need to clean their container regularly. Remove any dead mealworms and remove any uneaten food. You should also sift through the substrate periodically to remove any frass (insect waste) and change the substrate every few months.

5. Harvesting Your Mealworms

When your mealworms reach adulthood, they will turn into darkling beetles. These beetles lay eggs, which hatch into new mealworms. You can harvest your mealworms by sifting through the substrate and removing the beetles and larvae. Rinse off the mealworms in cold water and allow them to dry before feeding them to your pets or using them as a protein source.

6. Troubleshooting Common Issues

While raising mealworms is relatively simple, there are a few common issues you may encounter. If you notice a foul odor coming from your container, it could be a sign of bacterial or fungal growth. In this case, you should remove all the mealworms and substrate and disinfect the container before starting again.

You may also notice some mealworms turning black or brown. This could be a sign of stress, poor nutrition, or overcrowding. Make sure to provide plenty of space and a varied diet to keep your mealworms healthy.
