Les termites en France : comprendre et éradiquer

• How to identify the signs of termite infestation?

  Knowing how to recognize the signs of a termite infestation is the first step in protecting your property. Common signs include the presence of galleries in the wood, fallen termite wings, sawdust-like droppings and visible damage to wooden structures. If you notice any of these signs, it’s imperative to act quickly.

• Is Sarthe affected by the termite risk?

  Since the prefectoral decree issued on December 15, 2025, all communes in the Sarthe region are now considered to be affected or likely to be affected in the short term by the termite risk. The main aim of this decision is to provide a framework for the detection, prevention and control of these insects, which can cause considerable damage to buildings.

  In concrete terms, this decree does not mean that all homes are infested, but that increased vigilance is now required throughout the Sarthe region. It is part of a preventive and anticipatory approach, to avoid a silent spread of the phenomenon.

  For private customers, there are several points to bear in mind:

  • in the event of the sale of a property, certain information obligations may apply depending on the situation of the property;
  • any suspicious sign (weakening wood, galleries, subsidence, unusual marks) should lead to a serious diagnosis;
  • A declaration to the town hall may be required if termites are found to be present, in accordance with the regulatory framework in force.

  In this context, a termite diagnosis carried out by a specialized professional enables us to accurately assess the situation and, where necessary, define appropriate solutions, whether preventive or curative. To contact a termite control professional in Sarthe (72), click here.

  The prefectoral decree is therefore less a warning than a collective protection tool, designed to preserve buildings and better inform owners, buyers and local authorities about the termite risk in the Sarthe region.

• Complementary strategies: control and monitoring

  After successful treatment, it is essential to implement long-term control and follow-up strategies. This involves regularly monitoring the property to detect any potential termite activity, as well as implementing ongoing preventative measures.

• Which termite species are present in France?

  Several species of termites are present in France, the most common being subterranean termites (Reticulitermes spp.) and drywood termites (Kalotermes flavicollis). Les termites souterrains creusent des galeries dans le sol et peuvent accéder aux structures en bois, tandis que les termites de bois sec infestent directement le bois sec sans nécessiter un contact avec le sol. Understanding the behavior of each species is crucial to implementing an appropriate control strategy.

• How can you protect your property against termites?

  Fighting termites in France and choosing the right treatment methods are essential to protecting your property. Whether you opt for preventive measures or dealing with an existing existing infestationprofessional expertise is a valuable asset. Acting quickly and effectively can preserve the structural integrity of your home and avoid the considerable repair costs associated with termite damage.

• How do termites spread?

  Termites spread mainly through swarming. Winged breeders fly away from their colony in the spring. Couples then form, and some settle near a hollow in the wood. These termites reproduce to form a new colony. But swarming isn’t the only way termites spread.
  A termite colony can also develop through the transport of wood and plants, where contaminated soil can potentially be found. This soil is sometimes transported hundreds of kilometers away, and this is how another region can become contaminated by termites.

• What curative treatment is needed to eradicate termites?

  If an infestation is already present, curative treatment is required. Options include the use of termiticides, baited traps and thermal methods. These approaches specifically target the termites present, eliminating the infestation and preventing further spread.

• Should I call in a professional to combat termites?

  Termite management often requires the intervention of qualified professionals. Specialized companies use advanced methods, such as Sentri Tech, which offer precise termite elimination while minimizing the impact on your immediate environment.

• What conditions are favorable for termites in France?

  Termites are xylophagous insects that thrive in favorable conditions, particularly those associated with humidity. In France, the southern regions, with their warmer and often more humid climates, offer ideal conditions for termite activity. However, it’s crucial to note that termites can be found all over the country, and no region today is immune to their threat.

  In southern regions, termites can be more active and cause significant structural damage to buildings, starting with wooden structures. Higher temperatures and increased humidity favor their development and their ability to feed on the cellulose present in wood.

  Nevertheless, termites can also be found in the more temperate regions of northern France. Even if conditions are not as favorable, they can still represent a threat, especially in environments where humidity is present, such as coastal areas.

  So, to effectively combat the termite threat in France, it’s essential to adopt preventive measures, wherever you live. Regular inspections, preventive treatments and constant monitoring are essential to protect wooden structures from potential termite attack.

• Is there a link between the spread of termites in France and global warming?

  In general, global warming can potentially influence the distribution of species, including termites. Changes in temperature and weather conditions can create environments that are more favorable for the survival and reproduction of certain termite species. Regions that were previously inhospitable to these insects could become more welcoming due to changing climatic conditions.

  It’s important to note that the complex interactions between environmental factors, including climate, and termite biology make it difficult to accurately predict the impact of global warming on their spread. Specific scientific studies conducted by researchers in entomology and ecology are needed to assess these relationships in detail.

• Which departments in France are contaminated by termites?

  The termite threat is spreading across several departments and regions in France, requiring heightened vigilance on the part of homeowners. In addition to regions such as Provence-Alpes-Côte d’Azur with Var and Alpes-Maritimes, Occitanie with Hérault and Tarn, other parts of France are also affected. Termite departments can be found in Auvergne-Rhône-Alpes (Drôme, Rhône, Isère), Bretagne (Ille-et-Vilaine, Morbihan), Centre-Val de Loire (Cher, Indre, Loir-et-Cher, Indre-et-Loire) and Corse (Corse du Sud, Haute-Corse). Termites are also rife in Hauts-de-France (Pas-de-Calais), Île-de-France (Paris, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne, Val-d’Oise) and Normandy (Seine-Maritime). Historically highly infested with termites, the Nouvelle-Aquitaine region has seen the presence of this pest in a very large number of its departments: Gironde, Charente, Charente-Maritime, Corrèze, Dordogne, Landes, Lot-et-Garonne, Pyrénées-Atlantiques, Deux-Sèvres, Vienne, not forgetting the termite-infested Haute-Vienne. In Occitanie, the departments of Ariège, Aude, Aveyron, Gard, Haute-Garonne, Gers, Lot, Hautes-Pyrénées, Pyrénées-Orientales and Tarn-et-Garonne. The Pays de la Loire region is also heavily infested with termites in Loire-Atlantique, Sarthe and Vendée, as is Provence-Alpes-Côte d’Azur with Bouches-du-Rhône and Vaucluse. Vigilance must therefore extend to the whole of France, as termites are a widespread threat that requires constant attention.

  Faced with this reality, homeowners in these areas need to take a proactive approach to protecting their property from termites, starting with a termite diagnosis. The geographical diversity of these departments underlines the scale of the threat and the need for coordinated action. Termite control is thus becoming a national concern, requiring a variety of strategies and widespread awareness. The consequences of termite infestations are not confined to southern regions, and every département needs to take appropriate measures to minimize the risks.

  Sentri Tech’s specialist termite control applicators operate in a large number of these departments, offering their expertise to protect the properties of private individuals and businesses. With a personalized approach based on the characteristics of each region, these professionals guarantee effective protection against termites, contributing to the preservation of real estate assets nationwide.

• What preventive treatment against termites?

  Preventive treatment is crucial to avoid termite infestation. Preventive methods include the use of chemical barriers, termiticides and traps. These approaches aim to create preventive protection around wooden structures, deterring termites from settling in.

• Why are Gironde and Bordeaux the most termite-infested areas in France?

  Why are Gironde and Bordeaux the most termite-infested areas in France?

  Termites are a major threat to France’s building heritage, but some regions are particularly hard hit. Among them, Gironde, and more specifically Bordeaux, sadly holds the record for the department most infested by these xylophagous insects. Why this massive proliferation? What factors favor their development? And above all, how can we effectively protect our homes in Gironde and Bordeaux against termites?

  A climate conducive to termite proliferation

  Gironde enjoys a temperate oceanic climate, characterized by mild winters and hot, humid summers. This humidity creates a particularly favorable environment for subterranean termites, which thrive in damp soils and attack the wooden structures of buildings.

  In Bordeaux, where rainfall remains moderate but regular, termites find ideal conditions to settle in for the long term. Soil moisture facilitates their movement, while the mild climate enables them to remain active throughout the year.

  Sandy soil facilitates colony growth

  The soil of the Gironde region, and Bordeaux in particular, is largely composed of sand. Subterranean termites move underground through the galleries they dig. Loose, sandy soil gives them greater mobility and enables them to quickly colonize new areas.

  This geological factor explains why certain communes in Gironde, such as Mérignac, Pessac and the Bassin d’Arcachon, are just as affected by the plague as Bordeaux itself.

  Old buildings plagued by termites

  Bordeaux, a UNESCO World Heritage Site, boasts a remarkable historic center. But old architecture also means wooden structures that are often weakened and poorly protected against infestation.

  In Bordeaux’s historic districts, many buildings and traditional houses are built on wood foundations, which are a real boon for termites. Termites attack beams, frames and floors, compromising the solidity of buildings and sometimes necessitating costly renovation work.

  Contaminated wood transport spreads further

  Another aggravating factor: Bordeaux, as a logistics and port hub, sees large quantities of wood in transit, notably via the Port de la Lune. This transport of materials can contribute to the spread of termite colonies to new areas, accelerating their expansion throughout the Gironde.

  In addition, inter-regional trade in timber, furniture and recycled materials indirectly encourages the introduction and proliferation of termites in new buildings.

  A prefectoral decree to control termites

  In response to this threat, the Gironde prefecture has issued a prefectoral decree declaring certain communes in the department to be termite-infested. This decree requires property owners to report any presence of termites to the town hall, and to take the necessary measures to combat their proliferation.

  Property buyers also need to be vigilant: a termite diagnosis is mandatory when selling a property located in an area classified as at risk.

  How can I protect myself effectively against termites in Gironde?

  For homeowners in Gironde, prevention is essential. Calling on professionals who specialize in termite treatment can guarantee lasting protection.

  Sentri Tech’s applicators in Gironde offer solutions adapted to every situation, whether for preventive or curative treatments.
