Keeping ants as pets

So you are interested in keeping ants as pets? Then you have come to the right place! In this blog, we'll tell you a bit more about how to keep ants as pets. But maybe you are mostly wondering, why keep ants as pets? What's the fun in that?

This is a question we often get and are happy to answer. Keeping ants is not like keeping a dog or rabbit that you can cuddle and pet. Ants are an object of study, meant to be observed. Compare it a bit to fish. They swim around in a tank, you have to feed and clean them, but apart from that you can only look at them. It is exactly the same with ants. Only, the nice thing about ants is that a colony also expands. An ant colony is constantly changing and you are always facing new and exciting challenges that make it great fun to keep ants as pets.

But how should you care for, clean and study these animals? We are happy to explain that to you.

Starting to keep ants as pets

Before we start on how to keep ants as pets, we need to make one thing clear. Whereas with other pets it is fairly common knowledge how to take care of them, with ants it works slightly differently. Every colony is different. Each ant species is also different. So the care for each ant species is also different. For example, one species needs more heat. While the other species does not. But don't worry. All our ants come with a description of how to keep them. So this insight into keeping ants is a general description of how to care for most ant species.

Most people (in Europe) start with one of the following three species: Lasius niger, Lasius flavus en Messor barbarus. Do you get it pronounced? Most ant species have Latin names but in the Netherlands we know these species as the black road ant, the yellow meadow ant and the harvester ant. These species are very common and you can find out more about them by clicking on the names.

Most ants start out in a test tube. This is the ideal environment for ants to establish their colony. Yes, a queen establishes a colony all by herself. How that works we explain in this blog. Once the colony is founded, the ants move to a nest also called a formicarium. These come in different shapes and sizes.

Most ants generally eat sugar water and insects. The harvester ant as its name suggests, Messor barbarus, eats seeds. They collect these in the wild and chew them into ant bread. You offer this food in an outside world. The outside world is an area separate from the nest, often open, where the ants can collect their food and deposit their waste. The nest is the underground part and the outside world is the above-ground part.

Are Ants Good Pets?

Ants are excellent pets for anyone who wants something genuinely interesting to observe rather than something to handle. You will not pick them up and cuddle them. But you will watch tunneling behavior, foraging strategies, brood care, caste development, and colony-level decisions that rival anything on a nature documentary.

They work well for people with allergies to fur, limited space, irregular schedules, or a preference for low-maintenance animals. A colony can go a few days without food if you are traveling. They do not mind being left alone.

What Do You Actually Need?

To start keeping ants, you need four things: a founding queen, a test tube setup for founding, a formicarium (ant nest), and an outworld (foraging area). The queen is the heart of the colony. Without a mated queen, you have nothing. The formicarium is the artificial nest where the colony lives and raises brood. The outworld is the connected space where workers forage and you place food.

A full starter kit, queen, test tube, nest, and outworld, is the most convenient way to begin. Everything is matched in scale and works together from day one. Have a look at the starter sets available in the shop if you want a complete setup without having to source everything separately.

Best Ant Species for Beginners

The best beginner species is Lasius niger, the common black garden ant. It is native to most of Europe, easy to find, tolerant of mistakes, and forgiving of temperature swings. Queens are widely available and affordable. Colonies grow slowly but steadily, which keeps the challenge manageable for new keepers.

For something more impressive, Messor barbarus (the European harvester ant) is a popular second species. It is larger, more active during the day, and builds impressive seed caches in the nest. Pheidole pallidula is another great option once you have experience, offering the dramatic soldier caste that makes Pheidole so popular.

Feeding Pet Ants

Most pet ant species need two food types: protein (for growing brood) and sugar (for fueling adult workers). Crickets, mealworms, and fruit flies cover protein. Diluted honey or sugar jelly covers carbohydrates. Offer both two to three times per week when the colony has brood. Sugar should be available daily.

How Much Time Does It Take?

Active maintenance takes 5 to 15 minutes per week for a small to medium colony. That includes feeding, removing dead insects, and checking water levels. Watching takes as long as you want.

During the founding phase (the first few months before workers emerge), you barely need to do anything. Keep the setup warm and dark, check the water level weekly, and leave the queen alone.

Tips for keeping ants as pets

You are almost ready to start keeping ants. We do have a few good tips for you that you shouldn't forget.

1. Make sure your ants can always drink water

A common mistake made by beginners is not to give the ants drinking water in the outside. This is very important because without water, the ants quickly dry out and die. This, of course, is something you don't want. You can offer ants water in a test tube or in a drinking fountain.

2. The ants should experience as little vibration as possible

Ants do not like vibrations. Every time vibrations occur around the nest, the ants think the nest will collapse and then they panic. This panic is not good. Especially not for the queen. The stress she experiences can affect the queen's lifespan. So make sure the ants are on a cupboard or table that does not rattle too much and is not touched too often. A separate table or wall shelf is best. A queen NOT sitting still is not a good sign.

3. Your nest should always be 50% full

Many beginners move the ants to too big a nest too soon. This is not good for the ants. In a nest that is too large, part of the nest is used as a waste chamber. This can go mouldy, which is something you don't want in your ant colony. Make sure the ants occupy at least half of the new nest. If you're not sure or in doubt, you can always contact us or ask someone in the community for advice.

4. Don't leave food in the outside world for too long

If you leave your food in the outside world for too long, it is likely to get mould and possibly attract pests such as mites. Mites love waste and ants also produce waste. If you keep the outdoors neat and clean, you prevent the chances of this happening. It not only gives you more viewing pleasure but also makes keeping ants much more fun.

5. Inform yourself well and ask around in the ant community

You are not alone! There are lots of people who keep ants. Some are real experts and know everything there is to know about ants. We have a large network of groups that includes many passionate ant keepers. You can join these groups via this link. This is the best and fastest way to get answers to all your questions. If you really can't figure it out, you can always send an email to info@estheticants.com or contact us in another way. Planning to keep ants as pets? We would love to help you!

Is Ant Keeping Right for You?

If you want a pet that is low-maintenance, fascinating to observe, and fits any lifestyle, ants are hard to beat. The colony grows with you: what starts as a single queen becomes thousands of workers over two to three years. The long-term nature of the hobby is part of what makes it so rewarding.

The best time to start is when queens are available after the summer nuptial flights, typically from June through August depending on your location. With the right setup and a good beginner species, ant keeping is one of the most accessible and engaging hobbies in the invertebrate keeping world.
