Can Termites Reach High-Rise Flats?

Many residents of tall buildings feel safe from termites, assuming that insects from the soil cannot climb so far. The reality is more nuanced. It is less common than at ground level, but termites can and do reach upper floors in high-rises.

This guide explains how, and what to do.

The short answer

Yes, termites can reach high-rise flats. Subterranean termites can travel upward through wall cavities, shafts, conduits and cracks, building mud tubes as they go, as long as they can maintain moisture. Termites can also arrive in infested furniture, wooden fittings and building materials, and drywood termites can live in wood without soil contact. Moisture from leaks makes an upper floor more attractive. Regular inspection, treated interior wood and leak control are the main protections.

How they get up

1. Through the structure: Cracks, expansion joints, shafts and conduits link floors.
2. With moisture sources: Leaking pipes and water seepage allow foraging far above the ground.
3. On materials: Wooden furniture, boards and packaging brought into the flat.
4. By swarming: Winged reproductives can fly in and start colonies in damp wood.
5. Drywood termites: Colonies in wood, independent of soil.

Why high-rise flats are not immune

• Interiors use lots of wood and board.
• Many buildings have complex shafts and ducts.
• Leaks can occur on any floor.
• Termite problems in one unit can spread to others.

Signs to watch for

• Mud tubes on walls or around pipes and wooden fittings.
• Discarded wings near windows.
• Bubbling paint and hollow-sounding wood.
• Small piles of pellets or soil-like dust.
• Damaged wardrobes, doors or flooring.

What residents can do

1. Inspect wooden fittings yearly.
2. Repair leaks and manage dampness.
3. Choose treated or resistant wood and boards for interiors.
4. Check second-hand furniture before bringing it in.
5. Seal gaps around pipes and cables.
6. Report signs to the society promptly.

Building-level measures

Ask whether the builder treated the soil during construction and whether the society arranges periodic inspections and perimeter treatment. Share findings among residents.

When to call a professional

If you see signs, call a termite specialist. Because termites can spread through shared structures, they may check neighbouring units or common areas as well.
