Are ants pestering you in and around your home? With summer and the warmer weather, populations of ant nests rise and they become more active. Ants are often found invading our kitchens or marching across our decks in search of food, our food; the sandwich we innocently left on the breakfast bar or the glass of coke on the barbecue. With a little effort and some products found in good hardware stores there are ways to get rid of these pests and keep them away.

Finding The Source

Begin by taking a good look around the inside and outside of your house. Make a note of where you see ants. If you find trails of ants follow the ants that are carrying food; they will lead you to the entrances of nest sites. Mark the entrances so that they can be treated later.

Do not spray the nests with insecticide yet! Spraying the nest with insecticide will only serve to spread your problem. The ants will often just move to another site. If the colony is a multi-queen species this will mean multiple new nests.

To make it easier to see the ants carrying food you can sprinkle fine bread crumbs on their trail. Most often the nest is outside in sandy soil under paving stones or in cracks and crevices. Nests are usually on the sunny warm side of the house. Ants like warm dry nest sites.

Treatment

Your first treatment should be using ant bait which can be found from Kiwicare. Place the bait everywhere ants have been seen travelling. The more bait points you set the more bait will be taken back to the nest and faster more effective control will be achieved. Use either Ant Bait Stations, or place bait in clean containers such as bottle tops. The worker ants collect this bait and take it back to their nest where they feed it to the queens and larvae.

Ants change their feeding habits depending on the needs of the colony; sometimes preferring sweet sugary bait and sometimes they want more protein. Kiwicare liquid ant bait is sugar based and the gel bait has a high level of protein. If you notice the ants are not feeding on one type of bait, change it for the other type.

Replenish the bait regularly so that there is always fresh bait for the ants. Continue until very few or no ants are seen feeding on the bait. This may take up to two weeks in heavily infested areas.

Now you can spray the interior surfaces with residual deltamethrin or permethrin insecticide available from Kiwicare. Ants that walk over this insecticide surface spray will be killed, but trailing ants detect insecticide and will avoid it, so it acts as a barrier. If ants have been seen in the roof void use a bug bomb to treat this area.

Keep Them Out

Now put a barrier around your house to stop the ants from your neighbour’s taking the place of those you have removed. Sprinkle insecticide granules on the surface of flowerbeds and gravel or sandy areas around the house and water in. These products slowly release a ‘curtain’ of insecticide into the ground which acts as a barrier to ants that would burrow their way into your house. Also brush Kiwicare No Ants Sand into cracks and crevices to deny ants these spaces as new nest sites.

Spray or paint deltamethrin or permethrin residual surface spray around the base of the walls of your house and possible entry points such as doors, window frames, vents, downpipes etc. This will act as a surface barrier to prevent ants and other crawling insects getting into the house.

For areas where it is preferred that insecticides are not used Kiwicare produces an Organis NO Insects Barrier which does not kill ants but will stop them travelling where it is used.

Now deal with the nests. Sprinkle the slow release granules such as NO Ants Outside or NO Insects Lawngard Prills where nest entrances have been identified and water in. Routinely maintain these barrier treatments and you will remain free from ant problems in your home.

This treatment regime will control the pest ant species found in New Zealand. There are however some interesting differences between the species and how best to deal with each of them. I will discuss this in subsequent articles. Have a wonderful ant free summer.

    After spending $300 plus on Kiwicare Ant kill products I found them to be infective to control Argentine Ants.

  4. The difficulty in dealing with Argentine Ants. These ants were introduced to New Zealand in the last couple of decades and are now found in many places from Christchurch north.

    Argentine Ants are amongst the world’s most invasive species and have some habits that make them more than just annoying pests.

    • They form super-colonies, i.e. many nests can co-operate as if part of the same colony.
    • Super-colonies can become very large containing many hundreds of thousands of individuals.
    • The nests of Argentine ants will contain numerous queens, each with the ability to found a new colony.
    • The queens forage along with workers and so are easily spread accidentally on plant pots, boxes, cars etc.
    • When Argentine Ants move into new territory they attack and kill other insects and invertebrates removing the competition for resources.
    • Argentine Ants prefer high protein food when in this invasive mode. Most baits are higher in carbohydrate sugars. Note: Kiwicare NO Ants Gel Bait is higher in protein than the liquid bait.
    • Argentine Ants farm aphids once they are settled in a new territory. They feed on the sugary secretions from the aphids and protect the aphids from predators.

    You can find more information on Argentine Ants and how to identify them so you know whether they are the ants infesting your home or garden here.

    You will also find information on how best to control them.

    The main features of control are:
    • Baits are less effective. There is one specific Argentine Ant bait available but this is not likely to be fully effective on its own and it has a short shelf life, requiring refrigeration.
    • Barrier treatment using insecticide around the home both inside and outside can limit the ants to the garden areas where they are less of an annoyance pest. NO Ants Outdoors and NO Insects Lawngard Prills are particularly effective as a barrier both on the soil surface and subterranean.
    • Control of aphids on garden plants can help reduce ant numbers by preventing aphid farming.
    • Contact your local authority if you suspect Argentine Ants, they may have a specific control program in your area.
    • Contact Kiwicare for free and friendly advice.

    Thanks I will try this as I am sick of the ants they are everywhere. Climbing up the walls around the doorways all over the outside garbage bins, we wash them weekly sometimes more often but they still come back and cover the lids.
    I hope that this works!!!

  7. Hi Trish,

    You can prevent ants swarming over your bins by spraying them with NO Ants, NO Bugs Super or paint around the bottom of the bins with the Organic Ant Barrier made with ‘hot’ capcaicin from chili. These will act as barriers and keep the ants from feeding on the waste food in your bins.
