Ants Pest Control Services in Canberra

Ants cause problems primarily when they forage in buildings for food or water, or when they construct nests in buildings and gardens. When searching for food, ants can be attracted to a wide range of products, with different species preferring sweets, meats, fats or oils. They will also search indoors for water during dry periods. When desirable items are found many species will recruit fellow nest mates to help gather the food and return it to the nest. This can result in large numbers of ants appearing over a short period of time.

Of all insects that infest buildings, ants are the most common. There are many different species of ant. Each is unique in terms of nesting sites, habits, characteristics and feeding preferences.

Black Ants (Ochetellus)

Appearance

  • Shiny and black.
  • 2.5 – 3mm long.

Lifecycle

  • Larva hatches out of the egg as a white grub which is narrower towards the head. They are fed by the adults.
  • The larva pupates and appears creamy-white, looking similar to an adult. Sometimes they have a protective silk cocoon around them.The adult emerges with the three defined body sections: head, thorax and abdomen.
  • The length of time between the egg stage and ants emerging as adults can take 6 weeks or more; it depends on a variety of factors such as the species of ant, the temperature and the availability of food.
  • Fertilized eggs become female, unfertilized become males.

Habits

  • These ants are regarded as a nuisance and scavenge in kitchens, garbage and also dog excrement, therefore potentially spreading diseases such as salmonella.
  • Common Ants’ include the intensely black ‘Black House Ants’, and they are attracted to sweets.
  • The light yellowish brown ‘Coastal Brown Ant’ prefers to feed on meat products and grease.
  • The most effective con
    trol measure is to find the colony and treat it.
Coastal Brown Ant (Pheidole Megacephala)

Appearance

  • About 1.5-2.5mm long.
  • Tend to be yellow brown to brown.

Lifecycle

  • Eggs laid are small in size.
  • Larvae are fed by the adults and after several moults the larvae pupate.
  • Once adults, 3 different castes exist:
  • Workers are wingless and sterile that lives for approximately a year. Workers are the nest-builders, food suppliers, feed larvae, look after eggs and defend the nest.
  • Males are winged and exist to mate with females.
  • Females are also winged until after mating and are also the largest in size. Females become the reproductive queen of the colony and live for many years.

Habits

  • Nest in soil and build along pathways around the house including gardens and walls.
  • Dry areas for nesting.
  • Will excavate leaving mounds along foot paths and other areas that are unsightly.
  • Will attack foods around the property including meat, sweets, fruit and greasy foods.
Bull Ants (Myrmecia)

Appearance

  • About 18 – 20mm long.
  • Tends to be red or black.

Lifecycle

  • When a queen starts to nest she digs a small chamber to lay her eggs in. There is one queen ant that lays all the eggs and one or only a few males that are just there to mate with the queen.
  • The ant’s life cycle passes through egg, larva, pupa and adult phases.
  • Almost every ant is born female. The eggs hatch into small grubs, which grow into a particular caste (most are workers, then soldiers).
  • The queen Bull Ant leaves the nest at night to forage and supplement the food supply for her progeny (baby bull ants).
  • The queen may live for several years.

Habits

  • Very aggressive (if a nest is disturbed, there will be a massive outpouring attack).
  • Bulldog Ants typically nests outdoor in soil and under logs and rocks.
  • Located mostly in bushy areas (they seldom enter buildings).
  • They can inflict a very painful sting to humans.
  • The stinger does not remain in the victim, so the Bull Ant can sting repeatedly.
  • They feed on other insects and things such as honeydew from scale insects or plant nectar.
  • Each ant belongs to a specific caste and has a specific job to do (there are worker ants, soldier ants, the queen and the male – who mates with the queen).
Fire Ants (Solenopsis Spp)

Appearance

  • Queens 15mm long.
  • Workers 3-6mm long.
  • Coppery–brown on the head and body, with a darker abdomen.
  • Solenopsis has a very distinctive two–segment antennal club, which is most visible in the front view of the female reproductive ant.

Lifecycle

  • After swarming from the nest and mating, the queen searches for a suitable spot to lay her eggs. Once found, she can lay up to 125 eggs in late Spring.
  • Larvae hatch within 8 to 10 days, and the pupal stage lasts for 9 to 16 days.
  • Larvae feed on secretions from the queen’s salivary glands and broken down wing muscles until the first worker ants emerge. After this first batch of larvae moult into workers the queen’s role returns to egg laying – she can lay up to 1500 per day. Worker ants continue with larval care, nest building and food foraging.
  • Fertile males are produced later in the season.

Habits

  • Foraging workers diet consists of dead animals, including insects, earthworms, and vertebrates. Workers also collect honeydew and forage for sweet food, proteins, and fats.
  • Swarming characteristics – mating between queens and fertile males takes place on the wing mid to late Summer. Males perish after mating.
  • Nest locations can be a mound of up to 40 cm or next to objects found on the ground, e.g. logs.
  • If aggravated, these react aggressively and can inflict a painful sting, resulting in a pustule some 48 hours later.
  • These ants are a major agricultural and urban pest, destroying crops and invading residential areas both outdoors and indoors.
Garden Ants (Lasius Niger)

Appearance

  • Workers 4-5mm long.
  • Queens 15mm long.
  • Dark brown-black in colour.
  • 1 small segment at waist point (pedicel).
  • No sting present.

Lifecycle

  • Queens overwinter in soil. Eggs are laid in late spring.
  • Larvae hatch 3-4 weeks later.
  • Larvae feed on secretions from the queen’s salivary glands until the first worker ants emerge.
  • Worker ants continue with larval care, nest building and food foraging.
  • Fertile males are produced later in the season.

Habits

  • Foraging worker ants follow well–defined trails around food sources. Sweet foods are preferred but high protein foods will also be taken.
  • Swarming characteristics – mating between queens and fertile males takes place on the wing mid to late summer. Males perish after mating.
  • Nest locations – often outdoors in soil and below paving slabs on the sunny side of buildings.
  • Nest locations can be identified by the presence of finely powdered soil around nest exit holes.

  • It has a fairly painful sting.
Sugar Ants (Camponotus Consobrinus)

Appearance

  • This species vary greatly in shape, size and colour.
  • Range from 2.5 to 15 mm, and are some of the most often seen ants due to their size and often bright in colouring. Lifecycle
  • The ant’s life cycle passes through egg, larva, pupa and adult phases.

Lifecycle

  • The ant’s life cycle passes through egg, larva, pupa and adult phases.

Habits

  • Often nests in a variety of sites ranging from holes in wood to the roots of plants, twigs of trees and shrubs, between rocks or in the soil.
  • They can also be seen during the day however, they are most active at night.
  • They are unable to sting, but they do possess strong mandibles which can bite. In self-defense these ants are also able to spray acid from their abdomens to deter predators.
  • They feed on dead and lives insects, household waste and are attracted by sweet food.
  • They rarely enter houses.
White Footed House Ant (Technomyrmex Difficilis)

Appearance

  • Dark brownish / black colour.
  • Yellow-white feet.
  • Approx 3mm in length.

Lifecycle

  • A colony can contain up to a million ants, thus these are very invasive ants which can be hard to eradicate.
  • Nearly half a colony is made up of fertile females so reproductive capabilities are huge. These are winged and larger than wingless females.
  • Winged males mate once before they die, wingless males are capable of multiple mating.
  • Adult workers are wingless females and are the ones seen looking for food.

Habits

  • They do not bite or sting.
  • Although colonies are vast in numbers, they tend to spread out into satellite colonies which nest in different locations.
  • Ideal nesting locations outside include trees – in trunks or galleries that might have once been created by termites, under loose bark or plant debris, nearer the home in attics, under roof shingles, in wall voids, along fences and in outdoor furniture. Indoors they can be found in the kitchen area near bins or where food is stored or prepared.
  • These ants are attracted to sweet substances – plant nectars, flowers and sweet human food substances. Also attracted to aphids and mealy bugs which secrete honeydew.
  • Most likely to be seen foraging for food in large numbers, most likely at night if temperatures are high.
