Recognizing the signs of a woodworm infestation is the first step toward effective elimination. Common indicators include:

2. Bore Dust: Fine, powdery dust (frass) around or beneath the affected wood, a byproduct of larval feeding.
3. Tunnels in Wood: Visible tunnels within the wood when it is cut or broken open.
4. Weakened Wood: Wood that crumbles easily or feels spongy may be infested.

Treatment Methods

Once an infestation is confirmed, various treatment options are available:

1. Chemical Treatments:
   • Surface Sprays: These insecticides are applied to the surface of the wood, killing larvae as they emerge. This method is suitable for minor infestations.
   • Injectable Insecticides: For deeper infestations, insecticides can be injected directly into the exit holes, targeting larvae within the wood.
2. Heat Treatment:
   • Woodworms cannot survive temperatures above 55°C (131°F). Heat treatment involves raising the temperature of the affected wood to eliminate larvae and eggs. This method is effective but requires professional equipment.
3. Fumigation:
   • Fumigation is a thorough method for severe infestations. It involves enclosing the affected area and introducing a gas that kills woodworms at all life stages. This method should be conducted by professionals due to the use of hazardous chemicals.

   • Exposing infested items to temperatures below -20°C (-4°F) for several days can kill woodworms. This method is suitable for smaller, portable items like furniture or artwork.

Prevention Strategies
