Signs of termites in a Bali villa (and what to do)
Short answer: The most common signs are mud tubes on walls or foundations, timber that sounds hollow when tapped, small piles of discarded wings near windows after rain, and doors or windows that start to stick. If you see any of these, get an inspection before the damage spreads.

Signs to look for
Mud tubes: thin pencil-width tunnels of soil running up walls, pillars or foundations. Subterranean termites use them to travel between the soil and your timber.
Hollow timber: tap doors, frames, skirting and furniture. Wood that sounds papery or hollow has often been eaten from the inside while the surface looks fine.
Discarded wings: winged termites swarm at dusk after rain, then shed their wings. Small piles of wings on sills or near lights suggest a nearby colony.
Other clues include blistering or bubbling paint, sagging ceilings, doors and windows that jam, and fine dust or droppings near timber.
Why villas in Bali are exposed
Warm, humid weather keeps termites active all year. Many villas use timber for roofs, doors, ceilings and built-in furniture, and gardens bring soil and moisture right up to the walls.
What to do if you find signs
Do not disturb the tubes or spray random insecticide, which can push the colony to move elsewhere. Take a photo, note where you saw it and book a professional inspection.
A typical treatment maps the activity, drills and injects affected areas and builds a chemical barrier in the soil around the building so termites cannot return from the ground.
Prevention for new and old buildings
A soil pre-treatment during construction is the cheapest protection. For existing buildings, fix leaks, keep timber off wet soil, remove stumps and wood debris near the walls, and schedule periodic inspections.
Frequently asked
Can I treat termites myself?
Surface sprays rarely reach the colony and can make termites relocate. A professional inspection and targeted injection plus a soil barrier is the dependable approach.
How often should a villa be inspected for termites?
Once a year is common, and more often for older timber buildings or sites with known activity. Ask for an inspection after heavy rain seasons or renovations.
