The Best Ant Nest on the Market: Our New Ytong Formicarium Collection

Designed for Beginners. Built for Perfection.

If you are starting your journey into ant keeping, choosing the right nest is the most important decision you will make.

After more than three years of development, testing, and continuous improvement, we proudly introduce our newest generation of Ytong nests. A collection that is not only beginner-friendly, but also engineered to be the best ant nest on the market.

With over 200+ five-star reviews on our previous version, this upgraded lineup sets a new standard in quality, performance, and design.

This is not just a formicarium. This is the foundation of your colony’s success.

What Is a Ytong Ant Nest? A Ytong nest is made from aerated concrete, a highly porous material that behaves like a sponge. This makes it one of the best materials available for ant keeping.

It naturally absorbs and distributes moisture, creating a stable and healthy environment for your ants.

Compared to other nest types:

• Acrylic nests struggle with hydration

• Test tubes are limited and temporary

• Natural setups lack visibility and control
  

Ytong combines the best of all worlds:

• Excellent hydration

• Natural look and feel

• Clear visibility of your colony

Why Our Ytong Nests Are Different

There are many Ytong nests out there. None come close to this level of engineering.

Every single nest is:

• Designed and produced in Schinveld, The Netherlands

• Built with precision using a custom 3D printed outer shell

• Reinforced with stainless steel mesh and screws

• Engineered to prevent escapes, even if ants dig into the Ytong
  

What makes them the best:

• Superior moisture retention without leaking

• Safe hydration system with built-in mesh

• Crystal-clear visibility with strong contrast

• Durable, high-end construction

• Suitable for almost every ant species
  

These nests are not mass-produced shortcuts. They are the result of years of refinement and real-world testing.

Type A vs Type B: Choosing the Right Series

Our collection is divided into two distinct series. Choosing the right one is simple.

Type A (Red) – Precision & Smaller Species

• Designed to be used vertically

• Features narrow, straight chambers

• Ideal for ants under 10mm
  

Perfect for species like:

• Lasius niger

• Tetramorium

• Myrmica
  

Type B (Green) – Space & Larger Species

• Designed to be used horizontally

• Features larger, square chambers

• Ideal for ants over 10mm
  

Perfect for species like:

• Camponotus ligniperda

• Camponotus nicobarensis

• Larger Messor species
  

Simple Rule:

• Small ants → Type A

• Large ants → Type B

The Full Size Range: From Founding to XL

Each series comes in five sizes:

• Founding

• Small

• Medium

• Large

• XL
  

This allows you to scale your setup as your colony grows.

When to Upgrade

Always follow this simple rule:

• Move your colony when they fill about 50% of the nest

• Upgrade when they can fill 50% of the next size
  

This ensures:

• Proper humidity balance

• Reduced stress

• Optimal growth

Hydration System: The Core of Every Great Formicarium

Hydration is where Ytong truly shines.

Each nest includes a dedicated hydration port with embedded stainless steel mesh. This allows you to safely add water without any risk of escapes.

How it works:

• Add a few drops of water daily

• Ytong slowly absorbs and distributes moisture

• The material creates a natural humidity gradient
  

Important tips:

• Ytong works like a sponge, it needs time to absorb water

• Darker Ytong = more moisture

• Do not overwater, especially with Type A
  

For vertical nests (Type A):Water travels downward quickly, so hydrate carefully.

For horizontal nests (Type B):Moisture spreads more evenly and predictably.

Heating Your Nest (Very Important)

Heating is critical, and many beginners get this wrong.

Always heat from above.

Never place your nest on a heat cable.

Why?

• Bottom heating causes condensation

• It disrupts humidity balance

• It can stress or harm your colony
  

Heating from above creates a natural temperature gradient and encourages healthy behavior. Moving Your Ants Into a Ytong Nest

Switching your colony is simple if done correctly.

Best method:

• Connect the new nest to the outworld

• Apply gentle heat to the new nest

• Let the ants move on their own
  

They will naturally relocate to the better environment.

Once they move:

• Disconnect the old nest

• Enjoy your upgraded setup

Maintenance & Longevity

These nests are built to last for years.

Cleaning:

• Use a toothbrush under running water

• Be gentle, Ytong is a soft material
  

Prevent mold:

• Avoid giving a nest that is too large

• Small colonies may store waste inside the nest
  

Pro tip:

Take a photo of your nest when it arrives dry. This gives you a perfect reference for moisture levels later.

Why Ytong Beats Every Other Ant Nest Let’s keep it simple.

• Better hydration than acrylic

• More beautiful and natural than test tubes

• More visible and controllable than natural setups
  

If you are serious about ant keeping, Ytong is the upgrade.
