Coastal brown ants are one of the most common ants around Brisbane, and they are a frequent call in Mount Gravatt. They are small, light to dark brown and often go unnoticed until little piles of sand or soil start appearing between pavers, along the edge of a slab or even through gaps in tiles and skirting boards inside the house.
These ants live in large colonies with many queens and spread by budding off new nests nearby. That is why spraying one spot often just moves them along. The crew we book looks for the mounds and soil piles, checks how far the activity spreads around the house and uses a treatment that suits this type of ant, usually a mix of baits and a treatment in the soil where they are nesting. In older homes they sometimes come up through cracks in the slab or gaps under skirting boards, which can look like dirt tracked in from outside.
- Sand and soil piles between pavers, driveways and paths
- Activity along slab edges, weep holes and garden edging
- Ants pushing soil up through tile grout or floor gaps
- Baiting to reach the queens inside large colonies
- Soil treatment around nest sites close to the house
Coastal brown ants are more of a nuisance than anything, but they can make a mess of paving and get into kitchens looking for food, especially protein such as pet food. Keep pet bowls clean and sweep up the sand piles after the visit so you can see if new ones appear. Around Mount Gravatt, these ants are busiest from spring through summer, and paved outdoor areas and pool surrounds are where most people first notice them.
