Why are ants considers pest?

Ants are of vital importance to the environment as they help aerate soil by there daily behaviours, which in turn allows water and oxygen to reach plant roots helping  plants grow.

But why are they considered pest? Ants typically only become a issue when they enter buildings and residential homes in search of food and water or when they create nests in homes or gardens.

Ants look for food and water in homes

Ants are attracted to a wide variety of foods and liquids with different ant  species having different preferences for which are mainly put into 2 different categories sugar and protein feeders.which both require different treatment options.

Ants are also attracted to water sources and often  will search for water which can also lead them into a property even if a food source isn’t present. In most species scout ants will locate a food source and place a pheromone trail leading other ants back to it to help transport it to the colony .This often leads to  large numbers of ants quickly appearing around the food item of interest.

Ants are also know to infest electrical circuits board , hot water heaters as well as power points and light fittings where they can cost thousands in repairs and increase the potential risk of electrical fires.

Where do ants make nests in homes?

Ants typically create nest outside however when heavy rain  or extreme heat occurs they can move there nests into homes to escape the elements

When ants find there way inside the majority of pest ant species will often create nests within walls cavity and foundations as well as within indoor plants, and between fittings. Ants typically do not cause structural damage to buildings and structures .

Ants typically nest in outside gardens largely unnoticed by property owners however nesting can some times result in soil being dug up on lawns and gardens, around pots and between pavers resulting in a unpleasant look and can make surfaces uneven and unsafe . Some species can form nests with large  tunnels systems underneath the soil surface which can  Undermining the strength of retaining walls and interference with drainage systems as well.

Most homeowners don’t often realise that “do-it-yourself” ant eradication treatment can actually make things worse in a variety of different ways . Most pest sprays which are often purchased in hardware stores over the counter such as Bunnings are repellent which means the ants can detect it and Avoid it. While it may kill of some ants When they track over the product it doesn’t not transfer back to the ant colony itself meaning the treatments often fails and the problem isn’t resolved.

At clean and green pest managers we use a variety of non-repellent products these differ to repellent products as Ants  cannot detect these ant control products as they are invisible to them and, therefore them simply crawl  through them without noticing until it’s to late  . As these ants return to there colony , they are without knowing tracking the product with them and transferring it to the rest of their colony. Eventually , this eliminates all of the ants and most importantly  the queen. While this method is slower then repellent products , it nearly always results in the complete destruction  of the ant colony.

Our 5 Steps process for controlling ants.

At Clean & Green Pest Managers the job of controlling ants that invade property’s is a five-step process:


The first step is a thorough inspection to locate foraging trails, ant nesting areas and conditions conducive to ant infestations. Typically more than one species may be found in and around a structure. When inspecting for foraging workers ants,we  pay close attention to ‘lines’ where ants like to travel, such as expansion cracks in driveways and footpaths and along foundation walls, fence lines, etc.


By identifying the ant species our technician can use their in-depth knowledge of the species, habits and biology to locate and develop the most cost-effective control strategies for that particular species of ant.


While chemicals treatment are important part of any treatment plan we first start with a integrated pest management (IPM) program that addresses the current problem and identifies conditions that may contribute to the infestation. Correcting these conditions helps prevent future infestations and reduces the overuse of treatment products.


In most cases, effective control includes a pesticide application such as residual liquid sprays, dusts and baits in combination with non-chemical control procedures that eliminate conditions conducive to ant infestations, such as exclusion, trimming vegetation away from the structure, eliminating moisture problems, removing dead wood, and so on.


We continue to monitor or success of the program and are able to adjust our tactics if required.All our ant treatments also include a lengthy free service period meaning if the ants return so do we free of charge.

What you can do to prevent ant infestations?

  • Clean Up : Ants love to feed of crumbs or food often left in kitchen and dinning areas over night by ensuring all food is placed in bin and food in sealed containers this can help prevent ants being attracted into you house in the first place
  • Vacuum Often: By regularly vacuuming around your kitchen and dinning room floors you can help prevent a ant infestation as these are areas scout ants often look for crumbs and left over food scraps.
  • Wiping Down Surfaces: When ants find residue such as spilled juice etc on benches and floors. They inform other ants with there pheromone trails to help direct them to  food source. By cleaning surfaces you can help get rid of the potential food and trails.
  • Seal cracks and crevices: Sealing entry point where ants enter the property such as gaps around doors and windows frames can help prevent ants coming inside.
  • Trim branches: ensue all tree branches over hanging above your property are cut back as any with use these to gain entry into your property.
