Ants
Black garden ants are a nuisance but pose no risk to human health. Their nests are found in the soil in gardens or under floors. Garden ants swarm as they fly away to find a site to create a new colony each year. This occurs naturally and is usually over within 48 hours.
Pharaoh ants
Pharaoh ants can pose a health risk as they can spread infections by penetrating food packaging and contaminating food and water. They are about 2mm long and pale yellow / brown in colour. Pharaoh ants are only found indoors. They are very agile and are able to climb smooth surfaces.
