While DIY methods might seem cost-effective, professional pest control is far more effective in eliminating carpenter ants for several reasons:
Finding Carpenter Ants in your home
If you find a few winged carpenter ants inside your house, it likely indicates that a mature colony is nearby. This could mean:
that there is already a nest inside your home (winged carpenter ants emerge from established nests to reproduce and start new colonies).
If you find a few of these ants near a window or lights, they may have entered from an outdoor nest in rotting logs, trees or damp wooden structures. This would mean that there is a nearby outside colony trying to expand.
Carpenter ants prefer damp or rotting wood for nesting. Their presence could signal water damage, leaks or poor ventilation in places like basements, attics or window frames.
1. Identifying the Source – Finding the Nest
Follow the ants and check where they are emerging from inside your home. Carpenter ants don’t just live where you see them; they have satellite colonies and hidden nests, often in wall voids, roof cavities, or wooden structures.
Inspect wooden areas - look for sawdust-like frass, hollow wood or moisture damage.
Listen for faint rustling sounds - large colonies inside walls can sometimes be heard.
Call a professional pest controller - a thorough inspection can locate and eliminate the nest BEFORE major damage occurs. Professionals use specialised equipment (e.g., moisture meters, thermal imaging) to locate the main nest and ensure all colonies are treated.
2. DIY Methods Only Provide Temporary Relief
Over-the-counter sprays and bait stations may kill visible ants but won’t reach the queen and colony.
Carpenter ants relocate when disturbed, meaning you could accidentally spread the problem.
Professionals use targeted treatments that eliminate the entire colony, not just the foragers.
3. Using the Right Treatments to Eradicate Carpenter Ants
DIY products may contain low-concentration insecticides, which only reduce numbers temporarily.
Professionals use industry-grade solutions that are more effective and safe for pets and children when applied correctly.
4. Preventing Future Infestations
Carpenter ants thrive in moist, decaying wood, which often signals underlying property issues (leaks, rotting timber, drainage problems).
A pest control expert will not only eliminate the ants but also provide long-term prevention strategies, such as:
Sealing entry points
Identifying moisture sources
Recommending repairs
5. Cost vs. Long-Term Damage
Carpenter ants hollow out wood, weakening structures over time.
Delayed or ineffective DIY treatment could lead to expensive repairs to walls, decks, or roof supports.
A professional can eradicate the infestation quickly, saving money in the long run.
6. Safer & More Effective Than DIY Chemicals
Incorrect pesticide use can pose health risks to people and pets.
Professionals use eco-friendly and targeted treatments to ensure minimal environmental impact.
7. Guaranteed Results & Expert Advice
Most pest control companies offer warranties or follow-up visits, ensuring complete eradication.
They provide expert advice on preventing future infestations, tailored to your home environment.
Conclusion:
More than any of the DIY methods for eradicating timber pests such as the Australian Carpenter Ant, hiring a licensed pest control professional is the best way to ensure the complete eradication of Australian Carpenter Ants and protect your home from further damage. Professional treatments target both visible ants and hidden nests, preventing future infestations and safeguarding your property from costly structural issues
