Ants are among the most common pests in Australian gardens. While some species are harmless, others can disrupt plant growth, protect harmful pests like aphids, and even damage structures. Knowing the type of ants in your garden is crucial for effective control.
Common Ant Species in Australia
Black House Ants – Often invade homes but also disturb garden beds.
Greenhead Ants – Known for their painful sting.
Bull Ants – Aggressive and can harm plants and humans.
Sugar Ants – Attracted to sweet substances and can farm aphids.
Ants can indirectly harm plants by farming sap-sucking insects like aphids and scale, which weaken plants. If left unchecked, an ant infestation can lead to bigger pest problems.
Types of Ant Killer Insecticides
When it comes to ant control, there are several types of insecticides available:
1. Liquid Ant Baits
These contain slow-acting toxins that worker ants carry back to the colony, eliminating the queen and nest.
2. Granular Insecticides
Sprinkled around ant trails and nests, these are absorbed by ants and spread through the colony.
3. Contact Sprays
Fast-acting but only kill on contact, making them less effective for long-term colony control.
4. Residual Insecticides
These create a long-lasting barrier that kills ants over time.
Chemical vs. Natural Ant Control
Chemical Ant Killers
Chemical insecticides provide fast and effective results. Residual insecticides, which stay active on treated surfaces, can keep working for longer than a quick knock-down spray. Browse our insecticide range, and always check the label to confirm the product is registered for ants and for where you want to use it.
Pros:
Fast-acting
Long-lasting
Effective against large colonies
Cons:
Can be harmful to beneficial insects if misused
Requires careful application
Natural Ant Control Methods
Some people try home methods before using a chemical product. We do not sell these, and we cannot say how well they work. They may not clear a large or ongoing infestation. If you try one, take these precautions:
Diatomaceous earth: a dust that dries insects out rather than poisoning them, and it only works while it stays dry. The dust can irritate your nose, throat and eyes, so avoid breathing it in and keep pets and children away until it has settled. Use a product sold for pest control and follow its label.
Vinegar and water spray: sometimes used on ant trails. Vinegar can damage plant leaves, so keep it off plants you want to keep.
Essential oils: peppermint and tea tree oil are sometimes suggested for ants, but we cannot say they work. Tea tree oil can poison pets, especially cats, so keep it away from animals.
For a large or ongoing infestation, or if you are not sure what is in your garden, call us on 07 5537 4585 or read the label of a product registered for ants before you buy.
How to Use Ant Insecticides Safely
Using insecticides correctly ensures effectiveness while minimising harm to plants, pets, and beneficial insects.
Step-by-Step Guide:
Identify Ant Trails & Nests – Locate where ants are most active.
Choose the Right Product – Liquid baits for colonies, sprays for immediate knockdown.
Follow Label Instructions – Never exceed recommended doses.
Apply in Dry Weather – Rain can wash away treatments.
Keep Away from Children & Pets – Store products securely.
Safety Tip: Wear gloves and a mask when applying chemical insecticides.
Preventing Future Ant Infestations
Keeping ants away requires ongoing effort. Here’s how:
1. Eliminate Food Sources
Clean up fallen fruit and sugary spills.
Store compost bins away from garden beds.
2. Seal Entry Points
Use caulk to block cracks in pavements and garden walls.
3. Regular Garden Maintenance
Trim plants away from structures.
Remove decaying wood where ants nest.
4. Use Barrier Treatments
Apply a residual insecticide that is registered for ants around the garden perimeter, and follow the label for the rate and how often to re-treat.
