Carpenter ants are black in colour and vary between a quarter of an inch to, in some cases, three quarters of an inch long.  These ants are usually nocturnal and can be found travelling in long trails along fences, walls, trees and any linear pathway. Usually, Carpenter ants will make their nests in places such as the hollow trunks and branches of trees, although indoors they may be found in cardboard boxes or burrowing within the building’s walls and ceilings. Â
The commonly dubbed ‘Pavement Ant’, or Tetramorium Caespitum, is an ant native to Europe. It gets its nickname from the fact that these insects usually make their home under pavements and rocks. The pavement ant is an introduced species and is the most commonly encountered, house-infesting species of ant. Their colour varies between dark brown to black and their behaviour is usually controlled and managed through the use of various food baits.
