What you should know about ants and food

Why are ants attracted to food?

TL;DR — Quick Answer

Ants are attracted to food because they search for sugar, protein and fat to feed their colonies. Once a food source is found, worker ants leave pheromone trails that guide other ants to it. Keeping food sealed, cleaning spills quickly and removing crumbs helps reduce the risk of ant infestations.

Why Do Ants Come For Our Food?

Ants are always on the hunt for energy and building materials for their colony. A single scout can detect food from over 30 metres away, then leave a scent trail for hundreds more to follow.

There are more than 12,000 known ant species worldwide, with over 1,300 found across Australia alone. Queen ants can live 15+ years and lay millions of eggs — so a small line can turn into a big problem fast.

Section Summary: Ants track food easily, bring whole colonies, and grow very fast — stopping them early saves time later.

What Foods Attract Ants The Most?

Ants are not fussy eaters, but these five groups are their top favourites:

1. Sweet Foods & Drinks

Sugar gives ants fast energy — they will travel far for syrup, honey, lollies, pastries, juice, or spilled soft drink. Even a single drop of soda can feed dozens of ants.

2. Greasy & Protein‑Rich Foods

Grease, oil, leftover burgers, chips, or cooked meat are high on their list too. Worker ants need protein to help larvae grow — one study found 60% of Sydney home ant infestations link to leftover takeaway grease.

3. Dead Insects & Small Animals

Many species carry back dead bugs or small carcasses to feed the colony — this is why you often see ants near window sills or garden edges.

4. Damp & Spilled Food

Ants need water as much as food. Crumbs in the bin, sticky spills, or damp pet bowls are perfect targets — they can survive just on moisture for weeks.

5. Rotting Matter & Fungi

Some native Australian ants farm fungus from damp leaves or garden waste. Piles of mulch, fallen fruit, or rotting wood can draw whole colonies close to your home.

Section Summary: Sweet = energy, grease/meat = growth, damp = water, garden waste = fungus farms — keep all these sealed or cleaned up.

Simple Ways To Stop Ants From Food Sources

These quick steps work well for small numbers:

  • Wipe benches with soapy water or white vinegar to erase scent trails
  • Seal all sugar, cereal, and leftovers in tight glass or plastic containers
  • Empty bins every night and rinse food wrappers
  • Sprinkle pepper or peppermint oil along entry points — ants dislike the strong smell
  • Fix dripping taps and dry wet spots in the kitchen

Note: Boiling water kills surface ants but rarely reaches the whole nest — it can also damage garden plants or concrete paving in Sydney’s variable weather.

If lines keep coming back or you see nests inside walls, call us on 1800 819 189 — we find and treat the root cause, not just the trail.

Section Summary: Clean trails → seal food → remove moisture → treat nests — DIY fixes work for small groups, but nests need professional help.

Frequently Asked Questions

Can ants smell food through sealed containers?

They can detect very faint odours through thin plastic or paper. Use thick glass or heavy plastic with rubber seals for best results.

Why do ants keep coming back after I clean?

Hidden scent trails stay for weeks, or the nest sits under floors, paving, or walls — so new scouts keep finding the same route.

Are ants in food dangerous in NSW?

Most are harmless, but they can carry bacteria from bins or soil onto food. NSW Food Authority rules say you should discard any food ants have crawled over.

How fast can an ant infestation grow?

A healthy colony can double in size in just 4–6 weeks if they have steady food and water nearby.
