Importance of Correct Woodworm Identification

The presence of damage caused by wood boring insects does not always indicate a need for remedial treatment. However correct identification of the relevant beetle is essential if the correct chemical and method of application is to be selected.

If ‘green’ or partially dry timber has been incorporated into buildings any insect damage noticed may be historic, as they will usually have been killed during the drying process, therefore no remedial treatment may be necessary.

Adult wood boring insects are normally found only at certain times of the year, however a whole range of insects may be found indoors during the year. It is always best to call upon an experienced timber treatment contractor should you have any doubts.

Two of the wood boring beetles notably deathwatch and house longhorn may cause structural damage.

Both solvent based products and those that are water based may be used in the control of wood boring beetles.

Solvents in liquid form are usually sprayed onto the wood. Solvents in paste form are usually applied via brush or trowel.

Water based products involve 1 part concentrate added to 24 parts water making a 25 litre mix, these are usually applied via a sprayer. These sprayers may be hand held applicator types or electric pumps. Many of these chemicals have fungicide as well as insecticidal properties.

Thorough application of the chemical is essential in treating any of the wood boring beetles.

Diy bought products may be useful for treating a small piece of furniture for a relatively short time, but trade chemicals are needed to treat household roofs, floors, etc.

Sometimes discreet drilling of timber may be necessary, usually in oak beams, to facilitate uptake of chemical.
