The objective of remedial treatment in areas where woodworm or wood boring beetles have been discovered is to ensure that the conditions responsible for the decay are removed. The method of application of preservatives chosen will be the best possible in the circumstances to achieve the successful eradication of timber pests.
Spray treatment of timbers in-situ will be more effective if the following conditions are satisfied:
The spray application should cover all surfaces with a persistent insecticidal coating. Thus infected wood will be treated to achieve eradication and protection from future infestation and adjacent sound timber will receive a protective treatment.
The removal of severely damaged sapwood edges and any adhering bark is essential when treating timber infested by insects.
Timbers that are embedded in brickwork or masonry which are inaccessible, or of large dimension, should be treated with a bodied mayonnaise emulsion preservative. Any replacement timbers should be isolated from damp masonry by use of suitable PCA approved damp proofing material.
