Neighbour Has Bed Bugs: How to Protect Your Flat

You hear that a neighbour has bed bugs, and suddenly every itch feels suspicious. In an apartment building, it is a fair concern. Bed bugs can move between flats, and the best protection is a calm combination of checking, prevention and communication.

This guide explains what to do.

The short answer

If a neighbour has bed bugs, inspect your own flat for signs, particularly along shared walls, and take preventive steps: seal gaps around sockets, pipes and skirting where practical, keep the bed away from walls, use mattress encasements and interceptors, avoid taking furniture from the neighbour, and wash and heat-dry laundry. Encourage your neighbour and the building management to arrange professional treatment, since bed bugs rarely clear without coordination. Do not use DIY sprays pre-emptively, which can scatter bugs.

How bed bugs reach your flat

• Through gaps and cracks along shared walls, around pipes, conduits, sockets and skirting.
• Via shared corridors, lifts and laundry areas.
• On people, clothes, bags and furniture moved between flats.
• When a treatment drives bugs out of the neighbour's flat.

Step 1: Inspect your flat

1. Check mattress seams, piping, bed frame and headboard.
2. Look at sofas, wardrobes and furniture near shared walls.
3. Inspect skirting, sockets and wall cracks.
4. Look for dark spots, shed skins and live bugs.

Step 2: Take sensible precautions

• Keep the bed a little away from walls, and keep bedding from touching the floor.
• Use bed bug-proof mattress and pillow encasements.
• Place interceptors under the bed legs to monitor.
• Seal visible gaps around sockets, pipes and skirting on the shared wall.
• Reduce clutter so inspection is easy.
• Wash and heat-dry bedding regularly.

Step 3: Be careful with items and visits

• Do not accept furniture, bedding or clothing from the affected flat.
• Avoid lending or borrowing items.
• If you visit, keep bags off beds and sofas and inspect your clothes after.

Step 4: Talk and coordinate

1. Speak kindly to your neighbour. Blame does not help.
2. Encourage professional treatment and follow-up.
3. Inform the society or building management so they can coordinate inspections of adjoining units.
4. Offer your flat for inspection if the provider asks.

What not to do

• Do not spray insecticides around the shared wall as a precaution. It can drive bugs towards you.
• Do not panic and throw out furniture.
• Do not ignore bites and signs.

When to call a professional

If you find signs, call a pest control provider and tell them about the neighbour's problem. They may inspect adjoining units as well.
