Why do ants return shortly after I spray the trail?

Surface sprays only target the individual foraging ants you can see, leaving the colony and queen unharmed. Many ant species respond to chemical sprays by fragmenting the colony, which often makes the infestation spread and become more difficult to manage. Professional treatments focus on eliminating the nest itself.

What are the key differences between ants and termites?

While both can swarm, termites typically have straight antennae, equal-length wings, and a broad, thick waist. In contrast, ants have distinctively bent (elbowed) antennae, unequal-length wings, and a pinched, thin waist. If you are unsure, do not disturb the insects, as misidentified termites can pose a significant structural risk.

How long does a professional ant treatment last?

At Northern Rock, our standard package treatments include a 3-month ant-free service period. If ant activity returns inside this window, we will return to re-treat the affected area at no additional cost.

What attracts ants to kitchens in Darwin homes?

Ants in the Top End are primarily drawn to moisture rather than food. Kitchen sinks, taps, kettles, dishwashers, and leaking pipes are major attractants. While removing food residue and drying surfaces helps, it will not eliminate the colony, which is usually located outside the building.

Do ants nesting in walls cause structural damage?

Unlike termites, ants do not consume timber for food. They nest in wall cavities, sub-floor spaces, and voids because the environment suits their needs. However, they can still damage electrical appliances, wiring insulation, switches, and air conditioning units. Professional treatment is generally far more cost-effective than repairing this secondary damage.

Is professional ant treatment safe for pets and children?

Yes. We prioritise the use of family-safe and pet-safe products, which are applied specifically to bait points and trail areas rather than broadcast spraying. Your technician will provide a clear re-entry window (typically a few hours) to ensure the treatment is completely dry before family members or pets access the area.
