In Sils the termite climbs up from a plain that was once a lake: listening with audiotermes pinpoints every source and a TP8 biocide bait system acts on the entire colony, from the old town to Vallcanera.
Visual assessment visit included, at no cost and with no obligation. The technical study with audiotermes, which confirms every point of damage, is quoted separately and you decide with the figure in front of you. We work Monday to Saturday.

The Sils plain occupies the bed of the old estany, and that shallow damp keeps the subterranean termite active all year round. The village's low houses start their joinery almost at ground level, so the colony finds cellulose a few centimetres below the surface. The technicians locate the activity with audiotermes and cut it off with a bait system, bait stations with TP8 biocide checked station by station until the consumption is confirmed to have stopped.
The estany of Sils was for centuries a wide lake that was drained to gain meadows and cropland, and part of it has been recovered as a natural area. That past is still beneath the village: the ground of the plain holds shallow damp even in high summer, with wet meadows and irrigation ditches that spread it around. For a colony of subterranean termites, which needs permanently damp ground, it is a setting where it never goes thirsty in any month.
The village houses of the old town were raised right up against that plain, with a ground floor for farm use, rubble masonry walls and timber joists in the ceilings. They are low homes, and that means doors, frames and dado panelling sit very close to the ground. When the colony climbs it has no building to scale: the first usable joinery is a hand's breadth from the ground, and that is usually where it starts.
The station quarter tells another chapter of the municipality: it grew with the railway, in blocks of houses lined up beside the tracks and warehouses that have changed use over time. There, old floors sit alongside renovations done in phases, and it is common for a new floor to hide sleepers or battens inherited from the original build. That wood is out of sight, resting on cool screeds, and can register activity long before anyone notices anything on the surface.
Vallcanera and the hillside estates pose the opposite case: plots among pines and cork oaks, detached houses with a porch, pergola and log store, and gardens watered in summer. Outdoor wood resting on the soil offers the colony a direct bridge, and the watering keeps the perimeter damp when the hillside dries out. On these plots the inspection starts with the garden: sleepers, fencing and any piece in contact with the ground, before going into the house.
Zone by zone, what was built, what wood sits inside and where the insect gets in. It is the reading our technicians make before deciding where the check starts.
| Zone of Sils | Dominant construction | Wood present | Way in | First sign |
|---|---|---|---|---|
| the old town | Rubble masonry village houses | Ceiling joists and solid doors | Walls resting on the damp plain | Door frame going hollow |
| the station quarter | Blocks grown up beside the railway | Battens and sleepers under renovated floors | Screeds over the cool ground of the plain | Door that catches where it never used to |
| Vallcanera | Detached houses with plots among pines | Porches, pergolas and wooden fencing | Outdoor pieces driven into the soil | Mud tubes over the wood |

The data comes from our own technical case files. Open the case and you will see the date, the method and the case file number; anything that could identify the client or the property stays out.
The technical document of August 2026 studies a house in Sils from a preventive angle and puts everything into a single eleven-page reference: the inspection of the home's timber, the proposal for monitoring with bait stations and the follow-up calendar. It also includes a second conditional intervention, quoted separately, which would only be triggered if a check detected activity. The owners thus have a written plan with both possible responses defined before the termite gives any sign at all.
You do not need to see an insect. These three are what we actually find when we reach a home, and all three can be checked without tools.
Mud tubes the width of a pencil climbing the wall, the skirting board or the inside of a wardrobe. They are the tunnel the subterranean termite builds to shield itself from light and dry air. If they are damp inside, there is activity right now.
In spring the colony releases winged reproducers. They fly little, shed their wings quickly and pile up on a window sill or by a terrace door. Finding wings indoors means a mature colony nearby.
The termite eats the inside and spares a thin surface layer, so the element looks intact. Tap it with your knuckles and the sound changes from solid to hollow. On flooring it feels like a board that gives underfoot.
In Sils the spring swarming is noticed first over the plain: the ground of the old estany warms up before the Vallcanera hillside, and the wings appear on porches and in garages of the low houses.
Subterranean termite Reticulitermes spp.
Activity: from March to June · Peak: April and May.
Drywood termite Kalotermes flavicollis
Activity: from August to October · Peak: September.
These dates are indicative windows. Flight depends on temperature and humidity, so each year it starts earlier or later: if you see winged insects outside these months, it is still a reason for an inspection.

We start by listening. The audiotermes amplifies the sound inside the wood and locates activity without lifting the floor or drilling anything, and from that comes a floor plan of the property with every point of damage marked.
Then the stations go in. We place indoor bait stations over the located sources and outdoor bait stations spread around the building's perimeter, loaded with bait for subterranean termites, a TP8-type biocide. The perimeter barrier is the part most providers skip, and it is the one that reaches the whole colony.
From there it is a matter of checks: every station is monitored, the bait replenished and the activity recorded until the nest stops responding. There is no shortcut, and anyone promising eradication in one visit is not talking about subterranean termites.
We publish the real timescales because they pre-qualify better than any promise. If someone wants a fix in one afternoon, better they know before calling.
Total duration:Regular checks of the stations, with the calendar set when they are installed
Included
A walk through the property with the naked eye to see what there is and how far it goes. The assessment visit is included, at no cost and with no obligation, and it is the starting point when the signs are unclear.
1 working day, with the figure agreed first
Percussion sounding, listening with audiotermes, species identification and location of the access routes from the ground. We always recommend it: it confirms every point of damage and decides where each bait station must go. It is quoted separately, so you see it with the scope in front of you and it starts when you say yes.
A few days later
Floor-by-floor plan of the property with the issues found, the extent of the damage and the treatment proposal with your written quote. It is part of the technical study.
1 working day
Placement of the indoor bait stations over the sources and of the outdoor perimeter barrier around the building.
Every 6 to 8 weeks
Check of every station, bait replenishment and activity record. The frequency adjusts to what the system shows.
6 to 12 months
The timescale depends on the size of the colony. It is the real range of the bait system and it cannot be compressed.
3 years
Three years from eradication, with the annual inspection included at no cost.
The visual assessment visit is included, at no cost and with no obligation: when the signs are unclear, it is the way to clear doubts. Even so, we always recommend the technical study with audiotermes, a floor plan of the issues found and a report, which is quoted separately: it confirms every point of damage, fixes where the treatment must act and from it comes your written quote, so you decide with the figure in front of you.

Yes. The plots in Sils bordering the meadows of the old estany sit on ground that holds damp almost all year round, and that constant water is what a subterranean colony appreciates most. The centre is not off the hook, but next to the wetland it is worth checking the low wood first: dado panelling, frames and any piece in the garage or storeroom that touches the floor, listening with audiotermes if anything looks suspicious.
No. In the old town of Sils the bait system is installed without opening walls or lifting floors: the bait stations with TP8 biocide are fixed at every point with activity, and the outdoor stations go unnoticed once placed. Life in the house carries on as before during the programme, every check is a short visit, and when the treatment ends in eradication the 3 year guarantee is put in writing, with its annual inspection.
Yes. The trees around Vallcanera feed colonies that live off stumps and dead roots, and garden watering lays them a path to the plot when the hillside dries out in summer. The piece that usually gives them away is the outdoor wood: the foot of a pergola, a garden sleeper, the firewood stacked against the wall. Checking those pieces every season and lifting them clear of direct contact with the soil takes away the colony's easiest way in.
Yes, and in Sils it makes every sense: the plain keeps the damp the termite thrives on, even if the house is not yet showing any sign. A preventive study leaves the home inspected, proposes where to keep watch and sets down in writing how we would act if activity ever appeared, with that second intervention quoted in advance. It is what was done in a house in the municipality in August 2026: turning doubt into a concrete plan before having the problem.
Not necessarily. In the station quarter the wings of a swarming come in through any open window, and the nest that released them may be in a nearby yard, in a warehouse or under the street itself. What they do confirm is that there is a mature colony in the surroundings, so the sensible step is to inspect the wood that touches the floor and listen to the old floors with audiotermes before ruling the home out.
In Sils we cover the whole municipal area, including the old town, the station quarter and Vallcanera, and we also reach Riudarenes, Maçanet de la Selva and Vidreres. We work Monday to Saturday, 7:30 to 22:00.
Sils shares its comarca with Lloret de Mar, where the problem shows a different face: the turnover of holiday apartments delays the warning that in the lived-in houses of the plain goes off daily.
Termite treatment in Lloret de MarSils looks to Girona as its reference capital: there the same bait system works a different scene, joisted buildings of the historic quarter instead of low houses beside the plain.

The ROESP is the Spanish official register of pesticide establishments and services. It is the legal requirement for applying professional-use biocides, and not everyone offering these treatments meets it.
The technician who signs the reports, Sergi Casadevall Casas, has been treating termites and woodworm in Barcelona and Girona since November 2011, holding the biocide applicator licence. Visits are always made by our technicians, never by salespeople.
The conditions and timescales go in the intervention report, signed. For termites, 3 years from the certificate of colony elimination, with the annual inspection included at no added cost.
The technical study ends in a floor-by-floor plan of the property, with the issues found marked and the real extent of the damage. It is quoted separately and the document stays in the owner's hands, to work with the architect or to seek a second opinion with data on the table.
Spanish Royal Decree 830/2010 establishes that a pest-control company's registration in one autonomous community is valid to work in the rest. That is why we cover both provinces with the same registration and the same team.

We ask what you have seen and where. If the signs are unclear, we book the visual assessment visit, which is included and takes little time. And when the signs are there, what we recommend is the technical study: audiotermes, a floor plan of the issues found and a report, with your written quote so you decide with the figure in front of you. If the wood is healthy, we tell you that too: you save yourself the treatment.
