There are two
main types of ants, the black or garden ant and the pharaoh's ant. The
majority of ants are worker ants and sterile females which tend the young
and forage for food. The ants prefer to eat protein rich foods, such as meat, cheese, as well
as fats, sugar and chocolate.
Their characteristics. Black or Garden ants
usually nest outdoors, although occasionally nesting occurs under houses or extensions, or
under paving, in gardens or around walls. They are black and around 5mm in length.
Pharaoh's ants originated in North
Africa/Mediterranean region and are now distributed widely around the world. They require warm
and humid environments, which restricts them to internal areas in the UK. The ants are
yellow-brown in colour and very small, usually around 2mm in length. Nests are located within
the fabric of buildings, along heating ducts and in wall cavities.
The treatment. Garden ants require
insecticidal treatment to destroy their trails, but tropical ants, like Pharoah's ants, need
to be treated by baiting so that nests can be destroyed.
