Permethrin is a highly effective synthetic pyrethroid insecticide included in Sovereign M8 Woodworm Concentrate for its ability to eliminate and prevent wood-boring insect infestations. It is particularly effective against Common Furniture Beetle (Anobium punctatum), House Longhorn Beetle (Hylotrupes bajulus), and other wood-boring insects that threaten the integrity of timber structures.
Permethrin works by attacking the nervous system of insects upon contact or ingestion, leading to paralysis and eventual death. One of its key advantages is its residual action, meaning that once applied, it remains active within the timber for an extended period, providing long-term protection against reinfestation. At its concentrated level of 20% w/w, the formulation is highly potent, but when diluted to 0.20% w/w for application, it delivers effective insecticidal properties without posing unnecessary risks to humans or pets when used as directed.
Permethrin’s ability to bind within the wood fibres ensures deep penetration and prolonged efficacy, making it a crucial ingredient in the fight against woodworm and other wood-boring insects.
When handling and applying Sovereign M8 Woodworm Concentrate, standard safety precautions must be followed. Personal Protective Equipment (PPE), including gloves, goggles, and a dust mask, should be worn to prevent skin contact, inhalation of vapours, or accidental splashes to the eyes.
Always ensure adequate ventilation during application, particularly when working in enclosed spaces such as lofts or basements. The product must be kept out of reach of children and pets, and treated surfaces should not be accessed until the application has fully dried. Avoid contact with food, drink, and animal feed during use. In case of accidental skin contact, wash immediately with soap and water. If the product comes into contact with the eyes, rinse thoroughly with clean water and seek medical advice.
Refer to the product label and Material Safety Data Sheet (MSDS) for full safety guidance before use.
Sovereign M8 Woodworm Concentrate is suitable for use on a variety of timber surfaces, including structural beams, floorboards, roof timbers, furniture, and wooden panelling. It is effective on both hard and softwoods, ensuring deep penetration to combat active woodworm infestations and prevent future attacks.
The product is designed for use on bare timber only; any coatings such as paint, varnish, wax, or sealants must be removed before application to allow full absorption. Severely damaged timber should be cut back to sound wood to ensure the treatment is effective.
Before applying Sovereign M8 Woodworm Concentrate, all timbers must be clean, dry, and free from dirt, grease, and surface coatings. Any signs of dampness must be permanently resolved prior to treatment. Loose dust and debris should be removed using a vacuum cleaner or a stiff brush.
If the timber is severely damaged or structurally compromised, any decayed sections should be removed and replaced before treatment. To ensure deep penetration, it is essential that the timber is absorbent; any non-porous residues or surface barriers must be stripped away before application.
Sovereign M8 Woodworm Concentrate must be diluted prior to use. A single 250ml bottle should be mixed with water to produce 25 litres of ready-to-use solution. For best results, the concentrate and water should be at room temperature before mixing. The product should be applied at temperatures no lower than 5°C.
Application can be carried out using either a brush or a low-pressure sprayer. When spraying, take care to avoid inhalation and ensure even coverage of all exposed timber surfaces. The treatment should be applied generously, ensuring deep absorption into the wood.
To achieve the correct application rate, it is essential to estimate the total surface area to be treated and prepare the appropriate quantity of diluted product. Depending on the porosity of the timber, two applications may be required to achieve full penetration. If a second coat is needed, allow a minimum drying time of 30 minutes between applications.
The application rate for Sovereign M8 Woodworm Concentrate is approximately 3m² - 4m² per litre of diluted product. It is essential to ensure full coverage of all timbers, particularly end grains, joints, and hidden areas where woodworm larvae may be active.
Sovereign M8 Woodworm Concentrate will be touch dry within approximately one hour, depending on timber porosity and ambient conditions. Drying times may vary based on temperature and humidity. It is recommended to allow at least 24 hours for full absorption before overcoating or further treatment.
Unprotected persons and animals should be kept away from treated areas until the application has fully dried. The statutory re-entry time is one hour; however, it is advisable to allow additional time for ventilation in enclosed spaces before reoccupying the area.
Sovereign M8 Woodworm Concentrate does not alter the appearance of timber once dry, although treated surfaces may appear slightly darker while still wet. Once fully cured, the product is suitable for overcoating with most paints, stains, and wood finishes.
Overcoating should not take place until at least 24 hours after application, ensuring full absorption of the treatment into the timber. To maintain long-term protection, treated timber should not be exposed to prolonged wetting or excessive moisture.
All application equipment should be thoroughly cleaned with water immediately after use. Brushes and sprayers should be flushed out to prevent blockages and contamination of future applications. If the product has dried onto tools, mechanical cleaning may be required.
Sovereign M8 Woodworm Concentrate should be stored in a cool, dry place at temperatures between 5°C and 30°C. The product should be kept in its original container, tightly sealed, and away from direct sunlight or frost. Ensure the product is used within the manufacturer’s recommended shelf life for optimal performance. This treatment is intended for professional use and must be applied in accordance with all relevant regulations and guidelines.
