In this Silverfish Food Guide, we’ll cover everything you need to know about silverfish food, from what to buy, to how to make it yourself and when to feed your silverfish.

We’ll also cover some of the common mistakes people make when it comes to silverfish food.

What Do Silverfishes Eat?

Silverfishes are small insects that are usually found in damp and dark areas such as the bathroom or basement.

In the wild, silverfishes feed on a variety of things, including plant material, dead insects, and other organic matter.

They are particularly fond of starches, such as flour and cereal. Silverfishes also eat fungi and other decaying matter.

Although they are not known to be aggressive, they may feed on live insects if they are readily available.

Silverfishes are also known to chew on paper and cardboard, so it is important to keep your home clean and free of these materials if you prefer not to keep these critters outside of a terrarium.

Buy Silverfish Food

If you’re looking to buy silverfish food, you’ll be glad to know that there are plenty of options available.

I’ve personally found that caterpillar food works great for these moisture-loving critters as well as other common pet foods like fish and reptiles.

If you’re unsure what to buy, you can always experiment with different offerings to see what they may have a preference for.

When feeding your silverfish, it’s good to make sure that they are getting a balanced diet anyway.

You should mix up the types of food you offer them so that they’re getting a variety of nutrients.

This will help keep your silverfish healthy and happy. 

Lastly, it’s important to keep an eye on your silverfish to make sure they are in fact eating.

There’s no point in offering them food if they’re not eating it, so make sure to watch them make sure they’re getting enough to eat.

When To Feed Silverfishes

Silverfish are nocturnal creatures, so they tend to be most active at night.

As such, it’s best to feed your silverfish in the evening when they are most active.

It’s important to note that silverfish don’t need to eat every night, and they can go weeks without food, so don’t worry if you don’t have time to feed them every night.

You can feed your silverfish every couple of days, or once a week if necessary. 

Common Mistakes 

One of the most common mistakes people make when feeding silverfish is overfeeding them.

It is ideal to feed silverfish only what they can eat in one sitting, as any uneaten food can become moldy and attract pests. 

Another common mistake is that many people forget to provide fresh water for their silverfish.

Silverfish need access to fresh, clean water in order to stay healthy, so it is good to provide a source of clean water for them to drink from.


Understanding silverfish food is an essential part of keeping these insects healthy and happy.

With the right food, you can ensure your silverfish have a healthy and balanced diet.

While you can buy silverfish food from pet stores, you can also make it yourself with a few simple ingredients.

Whatever you choose, make sure to follow the instructions and avoid common mistakes to ensure you’re doing your best to care for these gentle night crawlers.

With this DIY food guide, you now have all the information you need to make sure your silverfish have the best food possible.
