Spider Food

Feeding spiders can be both a fun and important part of caring for your pet spider.

While spiders commonly eat insects, there are other food items that you can feed them.

In this article, we will explore the different types of spider food and how to provide this food for your spider.

I’m also going to help you avoid common mistakes that new owners make when trying to provide a balanced spider diet.

With these tips, you will be sure to feed your spider the tasty and nutritious meals that it deserves.

What Do Spiders Eat?

Spiders in the wild are known to eat smaller prey such as insects and other small arthropods.

This usually includes moths, flies, beetles, and other crawling critters.

Within a terrarium, it’s also worth mentioning they will feast on your clean-up crew (isopods, springtails, & millipedes) as well, so be mindful.

Despite their small size, spiders have quite a large appetite.

A single spider can eat up to three times its own weight in a single day.

Most spiders feed every day, though some species may go weeks between meals.

A spider’s diet not only consists of its prey but also of small items that may have become caught in their webs such as leaves and flowers.

Plant materials provide fiber and other important vitamins for a balanced spider diet.

Buy Spider Food

Buying spider food can be quite a daunting task, as it is difficult to determine what type of food to get for them.

Depending on their size, spiders will generally eat crickets, fruit flies, and mealworms.

You can purchase these at a pet store or online, or if you’re feeling adventurous, you can try to raise crickets and mealworms yourself.

Additionally, if you want to give your spiders something extra, you can also buy treats such as dried fruit or other uncommon insects.

No matter what type of spider food you choose to buy, it is important to make sure that it is properly quarantined.

Steps to feeding a spider

Step 1: Obtain appropriate live food
You should get food that is appropriately sized for your spider and won’t overload it. Suitable food includes crickets, mealworms, or fruit flies, which allows you to give multiple tiny insects all at once.
Step 2: Introduce the food to the spider
Carefully place the food in the container (or near the web if present). Doing so may cause the spider to be shy and hide away, so use tweezers to gently lower the food into the tank.
Step 3: Monitor the spider’s response
If the spider is hungry and awake, it will immediately walk toward the food and start eating. If not, it will walk away and hide.
Step 4: Leave the food Until it’s eaten
Typically, the spider will remain near its dinner until the meal is finished. However, if it moves away and hides, don’t worry, it will still happily eat the food when it gets hungry.
Step 5: Remove any leftover food
Any uneaten scraps should be removed to prevent mold or unwanted bacteria from taking over the tank.

When To Feed A Spider

Spiders should generally be fed once a week, and small insects should be offered in amounts that the spider can consume within a 24-hour period.

It is important to remember that different spiders may have different needs, so observing your spider is the best way to determine when it is hungry.

For example, young spiders may need to be fed every other day, while older, mature spiders may require less.

Additionally, the temperature of the environment can also influence your spider’s feeding schedule.

If it is particularly warm, they may become hungrier more quickly.

Common Mistakes 

When it comes to feeding your spider, there are a few common mistakes that can be made.

First, spiders often have particular dietary preferences that should be taken into account when selecting the food for them.

For example, some species of spider may prefer live prey like crickets or mealworms, while other species of spider may prefer smaller insects like flies.

Knowing what your particular spider prefers and providing them with that will ensure that you are providing them with the best nutrition possible. 

Second, many spiders like to eat their food immediately after it is offered, so feeding them too much or too often can be detrimental to their health.

Overfeeding your spider can lead to an unhealthy build-up of waste and uneaten food in the enclosure, and can eventually lead to health problems for the spider.

Therefore, it is important to feed them the right amount of food, as well as provide fresh food for them every day.

Finally, spiders are also delicate creatures and it can be easy to injure them when attempting to feed them live prey.

When introducing live prey into your spider’s enclosure make sure to place them carefully and from a distance, and avoid using your hands or any sharp objects.


At the end of the day, feeding your spider a well-rounded diet full of diverse food items is the best way to ensure that your pet spider will stay in tip-top shape.

Whether you’re a novice or an experienced arachnid keeper, it’s important that you understand how to feed your spider the right foods safely.

With the right knowledge in your pocket, your spider will be able to thrive and live a long and healthy life—so put on your thinking cap and get creative when it comes to spider food.
