They lack nestmate recognition so there is no hostility between colonies.
A single colony may contain as many as 2, workers, but the close proximity of multiple colonies can give the illusion of a single, large, supercolony.
Pharaoh ants are believed to have originated in the Afrotropic ecozone and were unintentionally introduced into Canada through human commerce.
Acclimated for tropical climates, pharaoh ants found in Canada usually reside in heated structures. Nests often include multiple queens, which are capable of leaving their existing colonies to establish new colonies nearby. This makes the pest particularly troublesome because queens can spread colonies throughout the home in a relatively short amount of time.
Unlike many species of ants, pharaoh ant queens do not need to leave the nest to mate, which allows for easier proliferation of the species. These queens breed continually and generally live between four months and a year. In a lifetime, a queen pharaoh ant produces about eggs, which are usually laid in batches of 10 to 12 at a time.
After a queen lays her eggs, the offspring take about 36 to 42 days to hatch and develop into adults. Reproductively capable males and females usually take a few more days to develop. Reproductives are usually spawned twice a year. New pharaoh ant colonies form through a process called budding. Queens in existing colonies and several workers leave nests to establish new colonies elsewhere. Budding allows for the insects to spread infestations quickly and into nearly any area of a structure.
Queens often choose undisturbed nesting locations, like wall and floor voids, but are capable of inhabiting tight, seemingly inaccessible areas, as well. Unusual places a pharaoh ant queen can form a nest include between linen sheets, inside of electrical wall outlets, and between books.
The budding process makes control difficult because infestation sources can be harder to locate. Additionally, if one nest is taken care of, a separate nest in the same structure can continue propagating the species. Inadequate control methods can exacerbate the problem by enticing queens to further branch out within a structure. With pincer-like jaws, some ant species are capable of biting humans and pets. As a small ant, only 1 to 2 mm in length, the pharaoh ant, or Monomorium pharaonis, does not bite.
Pharaoh ants are budding ants, meaning the species does not swarm but may still infest areas of Canada quickly by establishing new colonies often.
The insect has become a known pest of factories, office buildings, hospitals, and residences. Though the ant does not bite, the insect may detrimentally affect humans in other ways. The pharaoh ant carries and may transmit many diseases, such as salmonella, staphylococcus, and clostridium, which may cause botulism. While homeowners are usually safe from these pathogens, the ants may transmit disease in hospitals or health care facilities.
The pharaoh ant seeks warm, moist places, allowing for susceptibility in hospitals as ants may try to inhabit wounds under soiled bandages. Though not a threat to bite, the pharaoh ant may cause problems for homeowners, as the insect congregates on foods and dishes left unattended. Nests may be built in walls, between studs, or in insulation, causing limited structural damage. The pest may be considered more of a nuisance to homeowners. Termites, also social insects, also swarm periodically in structures; however, the distinct waist and elbowed antennae are reliable characters for distinguishing ants from termites.
Ants exhibit three distinct body regions, the gaster, thorax and head. The presence of pedicels between abdomen and gaster is what distinguishes ants from similar insects like wasps. Ants have one or two connecting segments between the abdomen and gaster. These segments are called pedicels, or nodes. Because some wasps resemble ants, the presence of these pedicels can distinguish ants from wasps.
Wasps may have narrow, even elongated, waists but they lack the distinct nodes characteristic of ants. Additional useful body characters of ants to include: a characteristic smell when crushed, presence or absence of a sting, and presence or absence of spines on the head and thorax.
Ant nests may be conspicuous or their nests may be hidden. Soil nests may have a distinctive shape, or they may assume the shape of their hiding place under rocks or other objects. When you find an ant nest in the soil, note its shape or pattern, as well as the number and placement of nest entrances.
Some ants nest in trees, either making their own cavities or, more commonly, taking advantage of existing cavities from rot or termite activity. Some ants, like carpenter and acrobat ants, may use your home as a substitute for their normal, preferred nesting site in a tree or shrub.
Besides length, an important feature that can help distinguish different ant species is whether the worker ants in a colony are all equal in size monomorphic or variable in size polymorphic. Ants can often be identified by behaviors that are unique to their species.
Notice how fast they run, how they form trails to the nest, how they carry food and distinctive postures when disturbed. Take a few minutes to observe what kinds of food they are carrying, if any some ants feed on liquids and may not be carrying anything visible. One of the most common ant species in eastern Texas and throughout the southeastern U.
In addition, fire ants make conspicuous mounds with no visible entrance holes on the mound itself. One of the most characteristic behaviors of the fire ant, however, is its aggressive response to nest disturbance including a vigorous and painful sting. Fire ants almost always nest outdoors, although they will enter buildings in search of food and water, especially in late summer.
Workers are variable in size, have a single pedicel, and a smooth, curved thorax in profile. Carpenter ants are mostly nocturnal, coming out at night to follow trails along fences, tree limbs, water hoses or other linear objects.
They do not sting, but can bite. They nest in hollow trunks and branches of trees, but will also make their homes in hollow doors, boxes, and the walls and ceilings of buildings. These medium-sized ants are frequently confused with carpenter ants because of similar coloration and nesting habits. Upon close inspection, however, acrobat ants are quite distinct from carpenter ants. Acrobat ants have two pedicels, workers are all the same size, and they have two spines on the thorax.
Unlike carpenter ants, they are mostly active during the day. When disturbed, acrobat ants lift their distinctive, heart-shaped gasters into the air as a defensive posture, much like an acrobat might balance on her hands.
Acrobat ants most commonly nest in trees, but will also make their homes in the walls and insulation of structures. Pharaoh ant. Geological Survey, Bugwood. They are yellowish in color with a dark-tipped gaster.
They have two pedicels and all workers are the same size. They make their nests in any dark, narrow space and may be found nesting in cardboard boxes, electrical boxes, in wall voids, etc.
