Ant

Black garden ant ( Lasius niger ) and pharaoh ant ( Monomorium pharaonis ) are the most common species. Both species create problems due to their search for food. Pharaoh ant poses a great health risk. Since they are usually found in dirty places (e.g. canals), they can easily carry disease microbes.

Their presence, especially in hospitals, creates a huge problem.

Black Garden Ant

Latin name:	Lasius niger
Length:	2 - 12mm
Color and features :	Worker ants are 2 - 5 mm in size and dark brown/black in color. Queen ants can reach 12 mm in length and are brown in color.
Habits and habitats:	Black ants nest outside. They often enter buildings to find food and water, and control is only necessary if they cause serious distress. There is a queen ant in each nest.
Reproduction rate:	A black ant nest has only one queen ant and there are approximately 5000 worker ants in the nest. The queen ant can live up to 12 years. Life span is 50 – 70 days.

Pharaoh Ant

Latin name:	Monomorium pharaonis
Length:	1.5 - 5mm
Color and features:	Worker ants are 1.5 – 2 mm in size and yellow-brown in colour. Queen ants are 3.6 – 5 mm long and dark red in colour. They have wings, but they cannot fly.
Habits and habitats:	They need warm, moist environments, so they are often found inside buildings. In warm climates, infestation may occur outdoors. Many indoor infestations can occur. There is more than one queen ant in a nest, so an infestation can spread quickly.
Life cycles:	38 – 45 days
Reproduction rate:	A pharaoh ant can lay more than 400 eggs in its lifetime.
