Of all the ant species that are regular or casual
household pests, the pharaoh ant is, along with the carpenter ant, the most
persistent and difficult to control!
Monomorium pharaonis (L.)
Pharaoh
ants are social insects that are easily distinguished from other insects because
their body regions are distinctly defined by very narrow attachments.
The pharaoh ant is an introduced pest and is native to the
tropics of Africa, but has spread throughout the world. The life cycle,
feeding habits, foraging behaviour, colony size, and distribution patterns of
this tiny ant all contribute to its pest status. In some locations,
particularly hospitals, food service establishments and apartment buildings,
pharaoh ants are the most serious pest alongside the cockroach and bed bugs.
Elimination must be the objective because control is usually not adequate or
acceptable.
The pharaoh ant is very small, one eighth of an inch long and
varies from yellow to reddish-brown in colour. The narrow waist has two
segments and the clubbed end of the antennae have three segments. Pharaoh
ant colonies may be fragmented and widely dispersed throughout a
structure. Colonies can contain as many as half a million workers and
thousands of queens (egg-producing females). Males are produced only
periodically and swarms of winged males and females are not common. Frequently,
mating takes place in the nest, and the formation of a new colony occurs when
queens and workers carry eggs and other immature stages of the ant to a new
location. New colonies can be established with one fertilized queen, five
workers, and 20 immature stages. Recently formed colonies may not forage
for several days, but soon make new trails and look for food. Nests may be
located outdoors in the lawn or garden, or indoors behind walls (in wall voids),
in attics, behind paneling, and in furniture or machinery. These ants are
frequently found in kitchens, bathrooms, or other rooms with accessible water
and warm temperatures-although their nest sites are dry.
Pharaoh ants feed on dead or live insects, and seem to prefer
meats or greases. They also eat sugar syrup, fruit juices, jellies and
cakes. In hospitals they have been found on open wounds and often infest
the dressings on patient's wounds. their small size, foraging behaviour, and
feeding habits, make the pharaoh ant difficult to control because They can nest
in such a wide variety of locations within a structure. Since they do not
follow specific trails to food sources, it is extremely difficult to trace a
trail to their nests.

More facts about pharaoh ants:
- On all ants the abdomen is attached to the thorax (the
segment bearing the legs) by a slender one or two segmented attachment
called a petiole. Pharaoh ants have two bumps called nodes, on their
petioles and they have a three segmented club at the end of their
antennae. For more about ant anatomy go back to
