What Foods Are Ants Most Attracted To ?
TL;DR — Quick Answer
Ants are most attracted to sweet, high-sugar foods (honey, fruit, syrup, lollies), greasy/protein items (meat, cheese, peanut butter, takeaway scraps), dead insects, plant sap/seeds, garden fungus, and damp, rotting matter. They locate food via long-lasting scent trails, can carry 50 times their weight, and Sydney’s warm, humid climate makes infestations common year-round.
How Do Ants Find Food Inside Your Sydney Home?
Ants have no teeth, but their highly sensitive chemical receptors detect food odours from metres away. Once a scout finds a source, it leaves a pheromone trail for the rest of the colony to follow.
These scent markers last anywhere from 2 minutes to 3 full days, depending on the ant species — so even a single spilled drop of juice can bring hundreds of ants hours later.
CSIRO data confirms more than 1,300 ant species live in Australia, with 30+ common across Sydney suburbs. Most are omnivores that will eat almost any edible item humans leave out.

What Sweet Foods Draw Ants the Fastest?
Sugar is the number one ant attractant. Their sense of smell is so sharp they can detect sugar at a concentration of just 1 part per 100,000 — equivalent to a grain of sugar dissolved in a full bathtub of water, per University of Sydney entomology research.
Top sweet targets in Sydney homes include:
- Honey, maple syrup, golden syrup and jam
- Fresh fruit, especially overripe bananas, mangoes and berries
- Lollies, chocolate, sweet biscuits and pastries
- Soft drinks, juice, cordial and leftover alcohol
- Crumbs from birthday parties, barbecues and picnics
Black house ants — the most common species in Western Sydney and Inner West homes — prioritise sugar above all other food types.
Why Are Greasy and Protein-Rich Foods Ant Magnets?
While workers crave sugar for energy, ant colonies need protein to grow larvae and raise new queens. Greasy, oily and meaty foods deliver concentrated protein and fats.
High-risk items in your kitchen include:
- Leftover takeaway containers and fast-food wrappers
- Cooking grease on stovetops, rangehoods and oven trays
- Peanut butter, cheese, full-cream milk and nuts
- Raw and cooked meat scraps, pet food and fish bones
Pharaoh ants — common in Sydney apartments, units and commercial kitchens — prefer protein over sugar and are notoriously hard to eliminate once established.
Per the Journal of Insect Science, a single worker ant can carry 10 to 50 times its own body weight, so even a 5mg crumb of sausage is easily transported back to the nest.
Do Ants Eat Other Insects and Dead Animals?
Yes — many species are carnivorous scavengers. When human food is scarce, ants hunt or scavenge protein from other insects, spiders and even small animal carcasses.
They will kill and eat rival ants, cockroaches, silverfish, flies and termites. Argentine ants — which form massive supercolonies across Sydney’s Northern Beaches and Eastern Suburbs — often wipe out native insect populations to secure protein supplies.
Under the NSW Food Act 2003, visible ant activity in food-handling areas is a critical breach. 2024 NSW Food Authority data shows ants caused 17% of all pest-related improvement notices issued to Sydney cafes and restaurants.
What Plants, Seeds and Fungi Do Ants Feed On?
Ants do not only eat human food — they forage extensively in gardens, which often leads them straight inside your home.
Garden food sources include:
- Sugary sap from rose bushes, citrus trees and eucalypts
- Flower nectar, ripe fallen fruit and tender new seedlings
- Grass and native plant seeds, which they store underground
- Fungus grown on rotting leaf litter (leafcutter ant species)
Leafcutter ants found in Sydney’s bushland suburbs carry cut leaves back to their nests to farm fungus — their only food source. Overgrown garden beds against external walls create a direct bridge for ants to move indoors.
Why Is Dampness and Moisture a Big Ant Attractor?
All ants need water to survive — they are drawn to damp, humid environments as much as food itself. Sydney’s average 70% annual humidity makes most homes naturally attractive.
High-risk damp spots include:
- Leaking taps, shower recesses and under-sink cabinets
- Rotting timber in subfloors, window frames and decking
- Dirty garbage bins and recycling with unrinsed food residue
- Condensation on windowsills and air conditioning units
Carpenter ants — a major structural pest in Sydney’s older sandstone homes — nest exclusively in damp, rotting wood. They do not eat the timber, but carve it out to raise young, causing thousands of dollars in hidden damage over time.

|---|---|---|---|
| Sugar, syrup, fruit, juice | Black House Ant, Argentine Ant | Very High | Kitchen benches, pantries, outdoor dining |
| Grease, meat, cheese, pet food | Pharaoh Ant, Coastal Brown Ant | High | Stovetops, dog bowls, under fridges |
| Dead insects, small carcasses | Argentine Ant, Green Head Ant | Medium | Subfloors, roof voids, garden edges |
| Seeds, sap, garden fungus | Meat Ant, Leafcutter Ant | Medium | Lawns, garden beds, paving gaps |
| Damp rotting wood, mould | Carpenter Ant | Structural | Window frames, decking, subfloor timber |

How Can You Block Ant Food Sources in Your Sydney Home?
Follow these simple steps to cut off ant supplies and make your home far less attractive:
- Store all pantry food in airtight glass or plastic containers — never leave open packets on shelves
- Wipe up spills immediately, including invisible sugar and grease residues
- Rinse all recycling and bin liners; keep bins sealed and clean
- Pick up pet food bowls after meals and do not leave food out overnight
- Fix leaking taps and improve subfloor ventilation to reduce dampness
Trim tree branches and bushes away from external walls — they act as natural highways for ants to move from garden food sources straight into your roof or windows.
Frequently Asked Questions
What smell attracts ants the most?
Sugar and fermenting fruit scents are the strongest attractants. Ants also pick up grease, meat and honey odours faster than almost any other household smell.
Why do ants come even if my Sydney house is clean?
They may be entering for water, or following an old pheromone trail from a spill months earlier. They also target invisible grease films on stovetops and tiny crumbs in hard-to-reach corners.
What foods naturally repel ants?
Strong scents like peppermint, cinnamon, black pepper and white vinegar disrupt their trails — but they do not kill nests. They work best as a temporary deterrent, not a permanent fix.
Are ants attracted to dry dog and cat food?
Yes — dry kibble is high in protein and fat. Coastal brown and pharaoh ants regularly infest pet food bowls, especially if left out 24/7.

Need Ants Gone From Your Sydney Home Fast?
Ant infestations are common across Sydney, particularly in kitchens, cafés, restaurants and food storage areas where food and moisture are readily available.
Residential and commercial properties can reduce the risk of infestations by maintaining good hygiene, storing food correctly and arranging professional ant control to eliminate colonies before they spread.
