Instructions about the breeding of Lasius...

It is essential to have prior knowledge before having ants. We particularly recommend the book  Criar Hormigas de Raul Martinez. (click here)

And if you want a more specialised book, we recommend Lasius (3,99€)(click here), concerning the breeding and care of Lasius.


Both books are available ONLY IN SPANISH.


Caution: We ship ONLY 1 COLONY or queen and ONLY 1 SPECIES per order or ant's nest, so you must choose correctly the one you want. We do not charge for the ants. They are FREE. You only have to pay for the shipping costs. 

You will receive the ants inside a test tube with food and water for two weeks. They were born inside the test tube and they are well there.


Difficulty of breeding: EASY

The colony is formed by the queen, 5-15 workers (its children) and eggs and larvae.


Instructions about the breeding of Lasius niger (small black ant):


Lasius niger is a very common species throughout Europe. The queen can live up to 28 years in captivity. (Suitable for begginers)


In nature they mainly live milking aphids. They also eat dead insects (they are scavengers). Therefore, they need to be fed with nutritious substitutes of the molasses from the aphid such as nutritious syrup ( and some dead insects.


Once you have received the ant colony, the first thing to do is to feed it if possible (water with sugar and derivatives). If there are too many ants, the best thing to do is to put them directly into the ant nest.

To feed the ants inside the test tube you can use a syringe. Insert the syringe needle through the cotton plug and put a droplet. This droplet must not be large because the ants could drown. Once they have drunk, remove the excess. A cotton bud can be used to clean, but be careful when you remove the plug because the ants can escape.

You can keep the ants in the test tube used for transportation as long as there is water inside. If you keep them inside the tube you must feed them at least twice a week.

To put the ants in the ant nest there are two methods:

- Pour out the contents into the nest, tapping to drop the ants off the tube.

- Place the tube, without the plug, in the ant nest or in the foraging area and wait the ants to relocate by themselves. This may require a lot of patience (days or weeks).

General details:

The most appropriate feeding is a diet based on liquid substances, such as nutritious syrup (, honey with milk and some newly dead insect (flies, crickets, silverfish, mealworms, etc). This diet has a high protein content.

It is VERY IMPORTANT that there is always WATER available, especially in summer. You can use water troughs, water gel (, the ants can drink directly from the humidity system (sand), from liquid food they take, etc.
