Xylophagous insects and fungi will feed on the woods that make up your house, both inside and outside: frames, parquet flooring. If you are looking for a curative treatment, there are various solutions on the market:
conventional insecticides (xylophenes, others) to get rid of xylophagous insects
fungicides to eliminate lignivorous fungi
Insecticide fungicides active on both woodborers and fungi.
natural insecticide treatments of wood as an alternative to xylophene
Woodborers (beetle, longhorn) are wood insects. Usually you realise that your wood is infected long after the first insects have taken a liking to your wood. It is the larvae deposited by the adult insects that reproduce and create damage to your wood. The larvae will live in your wood for an average of 1 to 5 years. After that, they will develop into adult insects and emerge from your wood. But when they emerge, they will lay eggs, which will develop into larvae that will attack your wood. It is a vicious circle, so as soon as you see any evidence of wood borers, you must treat. If your wood has been attacked, you may see many holes, wood dust, flying or dead insects near your wood.
If your wood has already been attacked by woodborers, you can use a "xylophene" type product. You will find "xylophenes" for exterior wood to treat a framework for example or "xylophenes" for interior wood for the treatment of beams and parquet floors. These products are very aggressive and toxic. The toxic substances contained in these products, which eradicate insects, will be released into the environment and into the air you breathe. Other insecticide products available on the market are boron salt products for wood treatment. They are just as toxic. This is why we will subsequently recommend a natural treatment against xylophagous insects as an alternative to xylophene.
If you live in a damp area, or have a terrace or a cladding, near, for example, a pond or a very damp garden, you should be particularly careful. You may have had stagnant water or splashes of water that damage your wood.
If your wood shows blue or black traces (mould), it has been attacked by fungi. You will often find fungi on beams and frames, which are wet areas. To recognise the merule, a very common fungus, you will find something like a white or grey spider's web.
To eliminate wood fungi, you can use a cleaner such as Wood Cleaner N100 or a fungicide product for moulds. These anti-blue wood treatments are mainly applied to exterior woods since there is no standing water indoors, so mould is rare. We recommend Sanitizing Primer For Wood PA400 to treat wood fungi and moulds and ensure that the wood is healthy. Once the primer has been used, you can apply a saturator to reinforce protection against humidity.
You will find many products on the market that are both insecticide and fungicide. In order to respect the health of the applicator and the environment, we advise you to use "natural" treatment products or products without conventional insecticides or fungicides such as Wood Bliss, the Wood Bliss High-C , the HM1 or Indian Patina. Also keep in mind that it is preferable to treat wood only when you feel it is necessary to do so in order to adopt a responsible attitude towards the environment.
We advise you to use a product that is both preventive and curative in order to treat your affected wood while keeping the product to do preventive work on your other woods.
The woods are classified in classes from 1 to 5. From class 2 onwards, which concerns exterior woods (frames, frameworks), the risks are linked to woodborers and fungi, which is why it is important to treat class 2 exterior woods as a preventive measure. You can use Wood Bliss or the Wood Bliss High-C (version concentrée du Wood Bliss ), a natural insecticide-fungicide treatment. This product, which consists of vegetable and mineral materials, can be used to treat and protect interior and exterior wood against wood borers and fungi. You can also use Indian Patina, a product formulated with vegetable and mineral materials.
First of all, you have to work on clean wood. Remove any parts of the wood that are too infected by insects.
Then you can apply your treatment. Insecticide fungicides are applied either by spraying or brushing the product on the infected wood in two coats 12 hours apart.
After the treatment of your wood, you can see a whitish layer appear. Don't worry, this is a sign of the product's effectiveness. Then you must inject the product into the infected areas (the flight holes) using a syringe sold in pharmacies. These natural wood treatments are odourless. It is therefore less unpleasant to apply than a chemical treatment.
You can also apply a preventive treatment against woodborers or fungi by spraying or brushing the product in two coats 12 hours apart.
You can also use insecticide and fungicide furniture treatments as a preventive measure every time you buy second-hand wooden furniture, for example.
