The most common type of ant found in the UK is the black garden ant, the red fire ant or pharoah ant. Ants are highly organised social insects. The worker ants will invade buildings in search of food. Ants are typically from 3 to 5mm in length and are attracted to sweet foods which they take back to their nest. Flying ants are the reproductive males (drones), these will develop wings in late summer and future queens will also develop wings in order to mate. Mating happens in the air and the queen will then seek out a suitable nest site where she stays for the winter, laying eggs the following spring in order to start up a new colony. A single queen ant can live for up to 15 years.   Garden Ants - (also known as Black Ants) - worker ants are 4-5mm in size but the Queen can be as big as 15mm. Queens lay their eggs in the spring in nests that are typically in soil but can be in brickwork or under bark. Garden Ants are attracted to sweet foods and leave a pheromone trail back to their nests for other ants to follow to the food source.   What is the Treatment?

Both workers and the Queen are a yellow-brown colour, almost transparent. Pharoah’s Ants originate from the tropics and require artificial heat in order to survive and reproduce and tend to live in large heated buildings such as hospitals, hotels, blocks of flats and restaurants. This ant’s diet is largely of decomposing foodstuffs and it carries harmful germs picked up from when it has been feeding. The pharaoh ant is named out of a belief that it may have been one of the insect plagues of Ancient Egypt.  Ghost Ants are becoming more common in heated buildings. These are a similar size to Pharaoh’s ants and are pale coloured with a dark thorax and head. Control must be left to professional operators.   What is the Treatment? Pharaoh ants have been exterminated by placing baits consisting of ground liver mixed with boric acid, in places where the ants forage. Renewing the baits once or twice may be necessary.
