Ants are common around Newcastle homes and businesses. A few ants entering from outside do not always indicate a serious infestation. However, repeated trails, numerous ants indoors or nesting activity around the building may require attention.
Foraging ants leave pheromone trails that help other members of the colony find food and water. Simply killing the visible ants may provide temporary relief without affecting the nest. Effective ant control starts with identifying the species, finding where the ants are travelling and removing the conditions attracting them.
Identify the Ant Activity
Look at where the ants are travelling and what they appear to be seeking. Common signs of an established ant problem include:
- Regular ant trails indoors
- Ants gathering around food, sinks or pet bowls
- Soil or debris appearing near cracks and wall openings
- Nesting activity in gardens, paving or wall cavities
- Winged ants emerging indoors or near the building
- Ant activity returning soon after cleaning
Different ant species have different nesting and feeding behaviours. Correct identification is important because a treatment that works for one species may be ineffective for another.
You can learn more about common species on our ants information page.
Find What Is Attracting the Ants
Ants commonly enter buildings while searching for food, water or shelter. Follow visible trails where practical, but avoid disturbing nests belonging to aggressive or stinging species.
Check for:
- Crumbs, grease and sugary spills
- Unsealed pantry food
- Pet food left out
- Leaking taps and pipes
- Condensation or damp areas
- Gaps around doors, windows and service penetrations
- Vegetation touching the building
- Aphid or scale-insect activity on nearby plants
Clean affected surfaces with ordinary detergent and water to remove food residue and disrupt pheromone trails. However, cleaning alone may not control an established colony.

Use DIY Ant Products Carefully
Registered ant baits and surface treatments may help with some minor ant problems when used according to their approved labels. Ant baits work by allowing foraging ants to carry the active ingredient back towards the colony. Results may therefore take time.
Do not spray insecticide directly over or beside bait stations unless the product instructions specifically permit it. Repellent sprays may discourage ants from feeding on the bait or cause them to establish alternative trails.
Avoid homemade pesticide mixtures and unproven remedies such as cinnamon, vinegar or essential oils as the primary treatment for an established infestation. They may temporarily disrupt trails without controlling the colony.
Always:
- Read and follow the product label
- Keep pesticides and bait stations away from children and pets
- Use products only in approved locations
- Follow ventilation and re-entry instructions
- Avoid applying pesticides near food or food-preparation surfaces unless permitted by the label
When to Contact an Ant Control Professional
Professional assistance may be appropriate when:
- Ant activity continues after cleaning and exclusion work
- Ants appear to be nesting inside walls or roof spaces
- Several trails are present throughout the property
- The species cannot be identified
- Ants return repeatedly after DIY treatment
- The nest is difficult to access
- The ants bite or sting when disturbed
Some ant species can cause painful bites or stings. In sensitive individuals, stings from certain Australian ants may cause a serious allergic reaction. Do not disturb an aggressive nest. If someone develops difficulty breathing, swelling of the tongue or throat, dizziness or collapse after a sting, call Triple Zero (000). healthdirect
A pest management technician can identify the likely species and choose an appropriate control method. Depending on the infestation, this may involve baiting, targeted treatment, nest treatment, exclusion work or follow-up monitoring.
Prevent Ants from Returning
After treatment, reduce conditions that encourage further ant activity:
- Store food in sealed containers
- Clean crumbs and spills promptly
- Empty rubbish bins regularly
- Avoid leaving pet food out overnight
- Repair water leaks
- Seal suitable cracks and openings
- Trim vegetation away from exterior walls where practical
- Keep external waste and compost areas maintained
- Monitor previously affected areas
Sealing entry points should support the treatment rather than replace it. Ants may find alternative gaps if an active colony remains nearby.
Ant Control in Newcastle
Persistent ant activity often requires more than treating the ants you can see. Newcastle Pest Exterminators can inspect the property, identify likely nesting and foraging areas, and recommend a treatment based on the ant species and property conditions.
