Ant Control in Your Home, Lawn & Garden

To control Ants nesting in the lawn, apply Yates Advanced Insect Killer For Lawns using a watering can or sprayer.

To control Ants nesting in gardens (around non-edible plants) apply Yates Home Pest Ant & Wasp Dust. Insert the nozzle into nest entrances and lightly squeeze the container to deliver the dust deep into the nest tunnels. The dust can also be applied on other areas of ant activity, such as on ant trails, into cracks of pavers and other infested areas.

To prevent Ants from entering the home, apply Yates Home Pest Long Term Barrier Spray to external surrounds of buildings, including window frames, air vents, and cracks and crevices where Ants may frequent or hide. Yates Home Pest Long Term Barrier Spray can also be used indoors. Spray surfaces including inside cupboards, door frames, window sills, skirting boards, behind sinks and other fixtures, and other surfaces where Ants may frequent.

To help control the Ants you can't see in and around the home, apply Yates Home Pest Ant & Nest Killer Gel Bait to nest entrances or along ant trails. The sugary bait attracts Ants, who take it back to their nest and transfer the bait to other workers, the queen and young, helping to destroy the nest. Replacing the bait regularly will help, especially if Ant activity is high. 

To prevent Ants from re-infesting pots, keep pots in a deep saucer of water sitting on a paver. The paver will stop the pot from sitting in the water and rotting the plant.

To prevent Ants from stealing seed, ensure seeds are well covered by soil. Ants prefer drier soil, always keep the soil moderately moist where seeds have been sown, this will also help to promote faster germination. Seed germination is temperature dependent, ensure seed is planted at the optimal time of year to increase rate of germination and reduce the time seed is available to Ants.

To reduce Ant activity on and near your plants, eliminate the pests creating their food source. Yates Nature's Way Citrus & Ornamental Spray controls various pests, including sap-sucking and honeydew producing pests such as Aphids, Whitefly, Leafhopper, Scale and Mealybug, it also controls Ants and Sooty Mould. Yates Nature's Way Citrus & Ornamental Spray can be used on many types of edible and non-edible plants for a variety of pests, making it a highly versatile and broad-spectrum insecticide to use in the garden.

Adult Ants are small, long and thin insects ranging in size from 1 – 50 mm in length. Ants vary in colours of black, brown, yellow, and are sometimes metallic.

At the front of the head are a pair of powerful pincer jaws and a pair of bent antennae. Jaws are used for sawing, transporting materials and are also used in defence and attack. Ants have two, generally large, compound eyes on either side of the head and three smaller simple eyes in the middle of the forehead.

Along the knobbly mid-section (thorax) are three pairs of legs. Some reproductive individuals of a colony have two pairs of transparent wings. Winged Ants are often confused with winged termites, however, termites have straight antennae and a thick waist.

Ants have a constricted waist and a bulbous abdomen (hind body section). Some Ants have a stinger at the tip of their abdomen which may be used to spray or inject poisonous secretions.

Ants are aggressive and ferociously defend their territory by biting and stinging. Ants are strong communicators and talk to each other via chemical signals. Some species are active at night while others are active during the day.

Ants are social animals that develop into colonies made up of anatomically and functionally different individuals known as castes. Castes are categorised into “Queens” which are reproductive females; “Kings” which are reproductive males; and “Workers” and “Soliders”, both of which are non-reproductive/sterile females. There may be one or more Queens and many Kings in a colony, both whose prime function is to start a new colony and breed. Workers and Soldiers are the most easily seen castes. Workers are responsible for the collection of food, for building and maintaining the nest and caring for the eggs and pupae. Soldiers primarily protect the nest.

Ants develop through a life cycle of complete metamorphosis – egg to larva to pupa to adult Ant.

Eggs

Eggs are small and ovoid.

Larvae

Larvae are whitish grubs, narrower towards the head.

Pupae

Pupae are similar to the adult, but soft, creamy-white and inactive.

Adults

Adults develop into different caste types including Queens, males, soldiers and workers (see behaviour section for further details).

Development from egg to adult may take 6 or more weeks. In many species, at certain times of year, large numbers of winged males and reproductive females are produced, swarm and mate. New colonies are formed by the fertilised females.

Depending on the Ant species, Ants may feed on:

• other insects
• insect residues, including honeydew from sap-sucking insects such as Aphids, Whitefly, Leafhopper, Scale, Mealybug, etc.
• fungi
• flower nectar
• sweet sap from trees
• seeds
• human and pet foodstuffs

Nests can be found under rocks, tree logs and other debris. Nests can also be also built aboveground and appear as mounds of soil and/or small stones, while others are hidden below ground. Nests can be built into an elaborate tunnel system made up of chambers for different housing purposes. Some ants produce silk and bind together leaves in trees to create “castles”. Ants also make their nests in the home. Nests can be found in indoor potted plants, wall cavities, roofing insulation, window frames and behind kitchen cabinets.

Insects, other Ants, Spiders, Snakes, Lizards, Birds and some Mammals. Short-Beaked Echidnas are Australia's very own Ant and Termite eaters.

Dry looking and dead patches in lawns and mounds of soil on top of the lawn. Symptoms in plants include wilted and dry foliage, brown foliage and/or dead plants. This is caused by excessive tunnelling by Ants, increasing evaporative loss of water in the soil, causing lawns and plants to dry out.

Ants generally do not damage plants directly but sometimes do steal freshly sown seed from freshly seeded lawns, garden beds and seed boxes.

Most damage to plants from Ants occurs indirectly. Ants form a symbiotic relationship with honeydew producing and plant-sap-sucking insects such as Aphid, Scale, Psyllid, Mealybug, Whitefly, and Leafhoppers.  Honeydew is farmed by the Ants and in exchange, pests are protected from predators. These pests feed on the sap of plants which can cause the new growth to wilt, plant health to deteriorate and in worse cases, result in plant death. Ants sometime physically carry these pests from one plant to another, further spreading the infestation. Sooty Mould is a secondary disease caused by excess honeydew remaining on the leaf surface and is a good indication of this kind of pest attack.

Bites and stings are often accompanied by redness, swelling, itchiness, burning and pain. There are various remedies for Ant bites and stings such as washing the site of bite or sting, applying a cold pack and/or applying an anaesthetic spray. If symptoms do not improve or if allergic to Ants, seek urgent medical aid.

Ants can be found in human and pet foodstuffs which can contaminate food. Some Ants may harbour plant and/or animal pathogens which may spread and transmit diseases.

• Lawns, garden plants, indoor and outdoor potted plants.
• Nests and excessive tunnelling caused by Ants can cause dead patches in the lawn and plants to deteriorate and/or die. This is due to evaporative loss of water in the soil, causing lawns and plants to dry out.
• Most damage to plants from Ants occurs indirectly. Ants form a symbiotic relationship with honeydew producing and plant-sap-sucking insects such as Aphids, Scale, Psyllids, Mealybugs, Whiteflies and Leafhoppers. Various plants prone to sap-sucking pests include:
  • Fruit trees such as Citrus, Apples, Figs, Peaches and Nectarines, etc.
  • Non-edible plants such as Roses, Fuchsias, Magnolia, Camellia, Azalea, Lillypilly, Murraya, Pittosporum, Viburnum, etc.
• Freshly planted seed can be removed from the soil and carried away to the nest. 

Exclude Ants from Buildings

• Treat cracks, crevices and entry points with dusts, granules or barrier sprays. Treat nests if possible.
• Reduce entry points to a building: repair holes, cracks and gaps in walls, skirting boards, windows and doors.
• Ensure flyscreens are fitted and maintained.
• If possible, cover vents with a fine mesh.

Reduce Availability of Water

• repair leaky taps and pipes
• remove unnecessary containers of water
• keep the lid of the toilet closed, especially outdoor toilets
• wipe up water on benches and in sinks

Reduce Availability of Food

• keep food in sealed containers
• clean outside of sauce bottles and jars
• dispose of garbage regularly
• ensure the house (particularly kitchen) is clean, including under and in appliances
• rinse food waste residues out of recyclable packaging
• place pet food bowls in a tray of water
• ensure house plants are free of sap sucking insects

Monitor Indoor Plants

• If Ants have been observed in the home, check indoor potted plants for Ant nests. Take Ant-infested plants outside and control for Ants. Check and control for Ant attracting, sap-sucking and honeydew producing pests. Bring back indoors once Ants and other pests have been controlled.

Avoid Bringing Ants into the Home

• Inspect plants, equipment and other items for Ants before bringing indoors.

• Ants are most aggressive when their nests are disturbed. Avoid approaching a nest unnecessarily.
• To evade painful bites and stings avoid setting up a picnic or laying on areas where Ant activity is observed and/or known.
• If you prefer using a spray to control and prevent Ants, Yates Home Pest Long Term Control Barrier Spray will kill Ants, together with Cockroaches, Spiders, Flies, Cat Fleas, Silverfish and Mosquitoes for up to twelve months indoors and up to three months outdoors. This ready to use barrier spray should be applied evenly over Ant prone surfaces, such as door entrances, window sills, cracks, crevices and around foundations, until moist.
