What Do Mealworms Eat?

In the wild, mealworms actually feed on a variety of decaying organic matter like plants, fresh fruits and vegetables, dead insects, and even bird droppings.

They’ll also feed on decaying things like fallen leaves, driftwood, and tree bark.

This is why they’re considered an essential component of the natural ecosystem’s food chain.

In addition to feeding on decaying matter, wild mealworms will eat things like fresh mushrooms, worms, fly larvae, and other small insects.

Wild mealworms also feed on grains, wheat, and cornmeal.

As you can see, mealworms are pretty versatile feeders and can find a variety of foods in the wild.

But, if you plan on raising them and want to provide the most nutritious diet for them, then you’ll probably want to create your own mealworm food.

This is where the DIY mealworm food guide comes in.

Buy Mealworm Food

Buying commercial mealworm food is another great way to provide your mealworms with a nutritious balanced diet.

You can find a variety of mealworm food options on the market ranging from oats and wheat germ to specially formulated diets.

When buying mealworm food, make sure to read the labels and ensure that it’s formulated for mealworms.

You’ll also want to avoid buying any food that contains pesticide residues as this can be dangerous for any animals consuming these mealworms.

Finally, it’s important to look for organic mealworm food as these are free from chemical fertilizers, herbicides, and pesticides.

When To Feed A Mealworm

When it comes to feeding your mealworms, it’s important to be consistent.

Mealworms should typically be fed every two to three days.

Mealworms like having a variety of food, so you should alternate between your normal food and healthy treats like oatmeal, apples, carrots, and other fruits and vegetables.

If you’re using a commercial food source, make sure to follow the dosage instructions on the package, as mealworms can easily become bloated if overfed.

Also, don’t worry if you don’t see your mealworms eating immediately – they can take some time to adjust to their new environment. 

It’s also important to note that mealworms should have access to fresh food at all times.

If a food source starts to look aged, discard it immediately and replace it with fresh food.

Mealworms will start to eat each other or parts of themselves if desperate and lacking a food source.

Furthermore, your mealworms may not eat when the temperature outside is too hot or cold, so adjust your feeding schedule accordingly. 

What’s more, make sure there’s plenty of humidity in your mealworm’s environment.

Mealworms need moisture in order to digest correctly and will become sluggish if they don’t have enough moisture.

The best way to keep your mealworms well hydrated is to spray them with water before feeding them and to also place a piece of vegetable in their environment.

Common Mistakes 

One of the most common mistakes people make when it comes to feeding mealworms is allowing their mealworms to eat the same food all the time.

This can lead to nutritional deficiencies in the mealworms if they aren’t receiving enough vitamins and minerals.

To avoid this, make sure to add variety to their diet and provide different types of food at least once per week.

Another mistake is overfeeding the mealworms. This can cause them to overcrowd their container, leading to stress and potential death.

Always make sure to follow the instructions on the package or recipe when determining how much food to give the mealworms so they can thrive.

Lastly, many people fail to clean out the mealworm food containers regularly.

Containers can quickly get contaminated with bacteria and other pathogens when food is left in them.

It’s important to clean the containers at least once a week to avoid any health issues for your mealworms.
