Ants in the Bedroom: Why They Come and How to Stop Them

Ants in the kitchen are expected. Ants in the bedroom, crawling along the wall, on the bed or around a bedside table, feel like an intrusion. They are following food, water or a trail, and the bedroom often offers more than we think.

This guide explains why ants come and how to stop them.

The short answer

Ants come into bedrooms for food crumbs, sweet items, drinks and spills, for moisture from attached bathrooms, plants or leaks, or because the bedroom lies along their trail between a nest and a food source elsewhere. They enter through cracks, gaps around windows, doors, pipes and sockets, and along wires and walls. To stop them, remove food and drinks from the bedroom, clean spills, fix moisture, seal gaps, trace the trail to its source, use ant bait rather than just spraying, and keep the room tidy.

Why ants come into the bedroom

• Food: Snacks, sweets, crumbs, drinks, chocolate and cosmetics with sugar or oils.
• Moisture: Attached bathrooms, leaks, damp walls and plant saucers.
• Warmth and shelter: Gaps behind furniture, in walls and around AC pipes.
• Trails: The room lies on the route to another food source.
• Nests: A nest in a wall, floor or nearby plant pot.

Where they get in

1. Gaps around windows and doors.
2. Cracks in walls and skirting.
3. Pipes, AC holes and wiring entries.
4. Switchboards and sockets.
5. Balcony doors and plants nearby.

Steps to stop them

1. Clear food and drinks: Do not eat in the bedroom, or clean up straight after. Keep drinks covered.
2. Clean: Wipe surfaces, vacuum crumbs, and wash bedding if food has been eaten in bed.
3. Find the trail: Follow the ants to the entry point or nest, and note where they come from.
4. Seal gaps: Use suitable sealant on cracks and gaps once you know the entry points.
5. Use bait: Place ant gel bait near the trail, away from children and pets, so that workers carry it to the nest. Avoid spraying the trail heavily.
6. Fix moisture: Repair leaks and dry damp areas.
7. Move or elevate: Keep the bed away from walls and do not let bedding touch the floor.

What not to do

• Do not spray strong insecticides on the bed or bedding.
• Do not scatter chemicals where children sleep.
• Do not ignore the source and just kill the visible ants.

Other things mistaken for ants

Winged ants after rain, termites and bed bugs can be confused with ants. If you have bites, check for bed bugs too.

When to call a professional

If ants keep coming back, a technician can find the nest, identify the species and treat safely.
