Sprays for Ants

There is some confusion about using sprays as part of an ant control programme. It is interesting to note that in almost all testing of spray insecticides against ants, measurement of success is through reduction of ant numbers and eradication of nests; repellency is regarded as a negative attribute.
Ant sprays should kill ants that contact treated surfaces, but killing foraging workers benefits colony eradication little, baits are more effective. There is greater advantage and satisfaction for a user in sprays being repellent and forming a barrier to ants; keeping ants out of buildings. Ants usually only become a pest when they enter buildings or areas where they are a nuisance.
However, if sprays are to be used to eradicate ants and kill off nests then they need to be non-repellent so that ants walk across treated surfaces. If repellent type sprays are used in or around nests it may serve to disturb the ants and cause budding of the nests and spread of the ant problem. Budding is where the queens and workers in a nest head off in different directions to set up new nests. This a particular risk when dealing with Argentine ants and darwin Ants.
Therefore, there is need for two forms of spray: one repellent, and one non-repellent.
The same holds true for granular, slow release insecticides. There is a dichotomy between eradication and control, killing and repellency.
For most home owners trying to stop ants being a pest, the repellent form of insecticide is more effective. Products such as NO Bugs Super (deltamethrin) or NO Ants (permethrin) from Kiwicare are good barrier sprays and can be used around building to stop ants moving in in search of food.
Kiwicare’s NO Ants Ant Sand (bifentrin) on the other hand is non repellent and can be used in and around nests to kill the nest without disturbing the ant nests or causing budding and spread of the colony.
If one continually cuts corners one ends up with a smoother running wheel.


  1. Hi Mr Brittain, my name is Ashley and I actually found your blog by accident.I was searching for control of borer beetles and your blog came up. I found your information most helpful.
    I am from Cape Town South Africa but I really wish I lived in New Zealand right now.
    I am currently doing pest control here in Cape Town, but things are a little slow here. Your blog has been a great help even though your information is based on New Zealand, South Africa and New Zealand's climates are similar and I think so are our pests. My cousin and her husband moved to New Zealand about 7 years ago, he is also in Pest Control.They seem to be doing very well for themselves. So Im very excited to hear things are going well for pest control in New Zealand.Once I'm fully qualified in PC, I will be applying for vacancies for Pc in NZ

  2. Getting rid of ant is very difficult. But proper technique can make the job quite easier. Maxforce Ant Bait is a good pesticide used for controlling ant infestation. Thanks for sharing this useful article.

    1. Yeah, I am agreed with you, that getting rid of ant is really very difficult. They very social insect and for this it is require to handle all the members of the hive at a time for getting rid of them completely.

    2. Thank you for your comment Pest Control.

      I would like to point out to readers that mattress covers, as linked by you, can only be a small part of a bed bug control program. They may prevent bed bugs using the mattress as a place to hide but this does not stop them using the bed frame, the carpet edges, bedside furniture, drawers, wardrobes, curtains, skirting, picture frames, etc, etc. found in a bedroom.

      Mattress covers also do not stop bed bugs climbing onto a bed and biting the occupants in the night.
