Ants in the Living Room: Hidden Food Sources

The living room is where we snack, drink tea, watch TV and play with children, and ants notice. A line of ants along the skirting or across the carpet usually means there is food somewhere that you have not found, or a trail that passes through on its way elsewhere.

This guide helps you find the hidden food sources and stop the ants.

The short answer

Ants in the living room are usually following food or sweet residue that is easy to miss: crumbs and sugary spills in sofa folds and under cushions, sweet drinks and snack wrappers, pet food and water bowls, sweet residues on tables and remote controls, honeydew on indoor plants, fruit bowls and open packets. They may also be passing through on a trail from a nest outside or in a wall. To stop them, find and clean the source, store food away, seal entry gaps, trace the trail and use ant bait, and keep the room tidy.

Hidden food sources

1. Sofa and cushions: Crumbs and sticky spills in folds and under cushions.
2. Coffee tables and side tables: Sweet drink rings, sugar and snack residue.
3. Remote controls and game controllers: Sticky fingerprints and crumbs.
4. Fruit bowls and snack jars: Open sweets and ripe fruit.
5. Pet bowls and treats: Food and water left out.
6. Indoor plants: Sap and honeydew from aphids or mealybugs.
7. Behind furniture: Dropped food that has been forgotten.
8. Waste bins and recycling: Sweet drink cans and bottles.

How to find the source

• Watch the direction the ants travel. Follow the line to where they gather or enter.
• Check where they are clustering: a corner, a bowl, a table or a plant.
• Look at where the trail leaves the room. It may lead to a wall crack or window.

Cleaning and prevention

• Vacuum sofas, rugs and under cushions regularly.
• Wipe tables, remote controls and surfaces with a damp cloth and a little detergent, which also removes scent trails.
• Keep food in sealed containers, and do not leave snacks and drinks out.
• Wash cups and plates promptly.
• Feed pets at set times, remove leftovers and wash bowls.
• Check plants for aphids and treat them.
• Empty bins that hold sugary items.

Block and treat

1. Seal cracks, gaps around windows, doors, skirting and wall edges.
2. Place ant gel bait along the trail, out of reach of children and pets, so that workers carry it to the nest.
3. Avoid spraying the trail heavily. It can scatter the ants and make baiting less effective.

If the trail comes from outside

Check the balcony, garden and walls for the nest and treat the entry point and perimeter. A professional can help with outdoor nests.

Safety

• Keep baits and chemicals away from children and pets.
• Do not spray on sofas and upholstery.

When to call a professional

If the ants keep coming back, a technician can identify the species and trace the nest.
