Caring for your first Lasius niger ant colony!
Basic information Lasius Niger

Difficulty level : 1/5
Queen size : 8-10mm
Worker size : 3-5mm
Soldier size : none
Hibernation : December-March at 5-10 degrees
Growth rate : 3/5

Lasius niger is a species in the Formicinae subfamily. These ants are very easy to keep and don't place high demands on their environment. They are also very stress-resistant. This makes them an ideal beginner's species.
Contents of the starter set
– Lasius Niger ant colony
A queen and a few first workers (nanitics)
– Cotton wool
To prepare a new test tube for example, also handy to use a small piece to offer liquids (no danger of drowning)
– (Fluon)
A specially developed prevention to keep ants inside the outside world. Shake well before use!
– Feeding syringe
Handy for administering sugar water in small amounts.
– Test tube outside world
Outside world for the ants where they get food and take away waste.
– 5x test tube 16 x 150 mm
Extra test tubes, for expansion, and / or replacement if the current one is contaminated or the water reservoir is empty.
– Sugar water and Honeydew, store in the refrigerator!
Liquid sugar water
– Fruit flies
Small test tube with fruit flies, it is best to store these in the freezer, then they will stay good for at least 3-4 weeks.
– Moving supplies
To be able to connect the colony to a new/clean test tube.
Setup with the starter set
First, you can connect the colony to the test tube outside. You can do this by folding the cotton pad in half lengthwise and wrapping it around the end of the piece of tubing. Then, push the piece of tubing with the wrapped cotton pad into the test tube. You can then connect the colony to the outside world. In the outside world, the colony can collect nutrients and dispose of its waste.
If necessary, apply a thin layer of fluon along the top edge of the outer chamber. This will allow you to open the lid at any time without any accidental escapes. Note that this product needs to dry (it will turn slightly white) before connecting it to the colony.
Offer food to ant colony
You can offer the colony various nutrients in the outside world, such as a small insect, or some honeydew or sugar water, 1 to 2 times a week.
Note: For a small ant colony, it's best to feed everything in small doses and remove excess food later. With liquids, even a tiny drop is enough for a small colony; any more and there's a risk of drowning. It's better to feed a little more often than too much at once!
Heating ant colony
We advise against heating an ant colony in a test tube with a heat mat or other heat source for beginners. If done incorrectly, the water reservoir in the test tube can overflow, drowning the colony. If the ant colony is large enough to fit inside an ant nest, it can be heated. In that case, heat a small portion of the ant nest with a heat mat or heating cable, placing it directly on the nest, not underneath it, as this can cause excessive condensation to form in the nest.
If you still want to heat a colony in a test tube, the best way to do this is with a heating cable. You do this by placing the cable at the beginning of the test tube and thus heating a small part.
With Lasius Niger this is not necessary if the ants are kept at room temperature and it does not drop below 15 degrees!
Ant colony in hibernation
Early December is the time to begin hibernation. Colonies will also show less activity around this time, and the queen will lay fewer to no new eggs. Gradually reduce the temperature over a few weeks. For example, by removing the heating at night or moving the colony to a slightly cooler room in the house. Ultimately, the colony can be kept at 5-10 degrees Celsius until March. Make sure they are not in a dried-out test tube (for example, a test tube should not already be empty or moldy when they go into hibernation). If this is the case, first move the colony to a new test tube. Feeding will be minimal during this time; rest is important (checking once a week is more than enough). Possibly introducing a fruit fly or a drop of sugar water to the outside world can never hurt. For small colonies (under 30 workers), hibernation is not yet very important, so you can choose this yourself.
How do I move an ant colony?
Moving an ant colony is very important, as you naturally want to ensure your ants' well-being. To move an ant colony, you'll need the T-piece connector and a test tube connector. Connect the colony to a new test tube and the outside world to the T-piece. The colony will then automatically move to the clean test tube. This can sometimes take a long time. If there's an emergency while moving the colony, for example, due to excessive mold on the cotton swab, an overflowing test tube, or an empty water reservoir, carefully transfer the colony to a clean test tube and then reconnect it to the normal setup.
When to expand to a nest and a larger outside world
If the colony grows too large for the test tube (this is when the test tube is very full of ants and you've given it maximum space), you can start purchasing a nest and a larger outdoor world. You can find these products on our nest and outdoor world pages
