The Formica sanguinea, also known as the Slave Maker Ants, is an intriguing and unique species that is sure to captivate any ant enthusiast. With their stunning red and black colouration, these ants stand out in any ant colony. This species is particularly fascinating for its behaviour of raiding and enslaving other ant colonies, making it a truly remarkable addition to any collection. These ants require a well-ventilated and structured habitat with plenty of space as these ants spray formic acid which can endanger the colony. As they are highly social insects, providing a diverse diet and ample space for their intricate network of tunnels and chambers is essential for their well-being. Polygenys ant species - multiple queens per colony. Not suitable for beginner antkeepers.
