Product Specification
Which Nest should I choose?
Choosing the right Nest depends on the size of your ant colony. The Small Nest is ideal for starter colonies with 1-30 ants, depending on the species. The Medium Nest is better suited for colonies that need more space, typically ranging from 30-150 ants. The Large Nest is designed for larger colonies with 150+ workers. Keep in mind that different ant species have varying space requirements due to their size. As your colony grows, you can easily expand their habitat by adding another Nest module.
Do you sell ants?
No, we do not sell ants. However, there are many reputable ant stores where you can purchase ants, or you can try to find ants in nature if it is permissible in your area. Always make sure to follow local laws and regulations, and treat all natural habitats and insects with respect.
Where do you ship your formicaria, and what are the shipping times?
We ship our formicaria internationally. Shipping times vary depending on your location. For orders within Sweden, delivery usually takes 1-3 days. For other European countries and the US, please allow a few extra days for delivery. We strive to pick and pack orders as quickly as possible to ensure timely shipping.
Do I need anything else besides the Nest?
Yes, in addition to the Nest, you will need an outworld where the ants can forage. We also recommend a liquid feeder, particularly for providing sugar water, which is essential for the health of your ant colony.
What ant species does this formicarium work for?
The Nest Formicarium is suitable for almost all ant species commonly kept by ant enthusiasts. The only exceptions are certain exotic species, such as weaver ants, which require a very high level of humidity that this formicarium may not be able to provide.
Can I return my products?
Yes, you can return your products. For more details, please refer to our returns policy.
Are the products suitable for kids?
Yes, our products are suitable for kids, but adult supervision is always recommended. Please be aware that the Nest Formicarium contains small parts that could pose a choking hazard to young children.
There is nothing as beautiful as Nest on the market today. All sizes are delicately designed to resemble natural ant nests. Our vision is for you to take these and then create your amazing miniature world from it, by combining the sizes to your liking together with our Outworld.
Nest is a design project years in the making, and we can finally say that thousands of ants have found their home here.
Nest and a majority of our other products are designed and produced in Stockholm, Sweden. We are happy to see the products spread across the globe. Maybe you have a colony living in them you want to share with our community?
We've gathered the measurements of all Nest sizes here for you. When buying a Nest you do not have to buy any extra Antgates, unless you have very specific connection needs. For normal usage, they are all included. The same goes for the sponges.
Nest Small dimensions:
Length: 6,4cm / 2.5"
Width: 3,4cm / 1.33"
Height: 1,8cm / 0.7"
Nest Medium dimensions:
Length: 6,4cm / 2.5"
Width: 6,4cm / 2.5"
Height: 1,8cm / 0.7"
Nest Large dimensions:
Length: 10,5cm / 4.13"
Width: 10,4cm / 4.1"
Height: 1,8cm / 0.7"
All three sizes of Nest work seamlessly together. They form a perfect shell-like shape when they are all assembled, but they can be arranged however you like. You can build your own version and create something unique.
Nest formicaria are built to be connected directly to our Outworld. But you can also connect to other brand's outworlds with vinyl tubing. Just attach the tubing to our "Antgate Tube" product and then connect the pieces.
Ich bin absolut begeistert von der Idee und Qualität des Produktes. Unsere Ameisen fühlen sich darin sehr wohl!!
My boyfriend is the one who started it all. But the previous “ant homes” just didn’t work out that great. Then I saw a commercial from your brand and it looked so much better than the white plastic versions I’ve seen. And the way you can close off the entrances is such a game changer. I’m very happy to say, now I got my own colony as well!
Nagyon jó!

We deliberately chose Ant Keepers because the nests look cool. Everything is very well made and serves its purpose. The drinking device and nectar dispenser are working just perfect. A minor drawback is that the connections between the nest and the arena are somewhat loose, which is why moving the entire setup can be tricky. We are still extremely satisfied and our Mesor Barbarus colony is thriving. Shipping was also excellent and everything was very well packaged. Thanks to Ant-Keepers
Es ist einfach super cool
Mycket nöjd med kvalitet och utseende på antkeeper produkterna. Naturligt utseende och bra passform på delarna. Smidiga funktioner med fuktning och att kunna stänga av utgångarna! /B&V
After years of keeping ants and trying nests from different manufacturers, this is genuinely my favourite formicarium I’ve come across. It’s rare to find something that combines aesthetics and functionality so successfully. The ants seemed to agree. They basically took one look and said, “We’ll take this,” then moved in within minutes.
The craftsmanship is excellent, the natural chamber layout feels intuitive, and the entire setup has clearly been designed by someone who understands both ants and antkeepers. It’s not the cheapest option on the market, but the quality, design, and attention to detail justify the price.
I’ll definitely be placing another order.
Highly recommended! :)
I bought a medium sized ant farm and it’s is amazing, it is very easy to access and alter and enjoyable to set up and use. I can’t wait to get my first colony when they have finished hibernating. I would definitely recommend it to anyone who would like to try any keeping or wants to try a new way of keeping them.
Ants have settled in well
It was a kids long time wish to have a pet at home and due to the work commitments and high maintenance of other animals my idea to discover the world of ants through the ant farm of AntKeepers . We are only few weeks into the ant farming but we already love it. We enjoy observing the ants together with the kids, learning about them and connecting through what has now become a shared family activity. I hope the excitement continues and through the ants world my kids learn to connect and be more interest with nature and biodiversity as well as have another together activity with me.
This habitat was a perfect addition to the ant colony. The ants immediately moved from an older habitat to this one. All the attachment points and doorways that can close made the transfer easy -they moved on their own! Grandchildren love being able to watch their little friends in their new house!
Wir sind super zufrieden. Das Ameisennest und Zubehör ist alles hochwertig. Wir lieben, dass wir es immer wieder erweitern können. Einfach super!
The anthill is printed very well and with great details. The ants immediately liked it.
I ordered the starter kit for keeping ants and love it! Everything arrived intact, my order was correct, and best of all the product is superior. My family is excited to be into the ant keeping hobby and we will purchase again from Antkeepers.
Wonderful, Melanie!! Happy to hear it, and I hope your family will enjoy it. Good luck with your ant colonies. /Linus
Meerdere spullen besteld voor de ant world van mijn zoon. Tot 2 x toe ging de bezorging niet goed via PostNL. Dit was buiten de schuld van Antkeepers maar Linus van Antkeepers was zeer meegaand en is het derde pakket uiteindelijk gearriveerd. Linus was zeer goed bereikbaar en reageerde snel op mij mail. Niets dan goed over de service van Antkeepers. Het product zelf ziet er ook goed uit, nu de mieren nog, die komen deze week😁. Dank je wel Linus voor je service.
Groeten Niels
Hey Niels! Heel erg bedankt voor je leuke review! Fijn dat alles uiteindelijk goed is aangekomen. Dank voor je geduld! Superleuk dat de mieren deze week arriveren—ik hoop dat ze zich snel thuis voelen. Laat het vooral weten als ik ergens mee kan helpen!
Veel plezier met de ant world! 😊
Groeten, Linus

Hey Niels! Thanks for your kind words! I’m really happy we got everything sorted in the end. Appreciate your patience, and great to hear the package finally arrived! Super exciting that the ants are coming this week—hope they settle in nicely. If you ever need anything, just let me know.
Wishing you and your son lots of fun with the ant world! 😊
Best, Linus
I bought the small nest and outworld and it has been great so far!
Nest got accepted super fast by the ants, I got no worries that one of my ants will escape if i change or add something about/to the layout because of the extra doors. Nest modules are looking great and clean, definitely recommend.
Awesome company i will definitely use in the future
I ordered so far 3 Antkeeper farms and the nests are the best looking in the market in Europe so far. It was important for me that the farm is modular so I can infinitely add new nests and outworlds as my colonies expand. A messor minos hesperius and a camponotus pseudoirritans colony have already moved in and they like it, it took only 30-40 minutes for them to find and start to use the nests, which means it is exactly what they need by instinct. I am a happy customer and will come back to buy more moduls
Very well built environment, modular and easy to expand, and also good to connect to the outworld and test tubes. It is perfect!
Very fast delivery, considering it was EU to UK. great formicarium for a beginner with useful features and detailed information in the pdf.
Bought a startset with some additions. Clear communication and the products meet the expectations. Cant wait till my colony grows or we decide to take in another species, so we can order more parts (a concept order is already in the making).
Ants love it
