Woodworm treatment options depend largely on the size and location of the spot of infestation. A professional pest control technician is likely to understand the probable cause and time of the infestation before carrying out the treatment. Professionals prefer to use the instruments called the borescope to examine the spread of the infestation. They also see whether the woodworms have caused any damage to the wood piece or timber, which are unseen behind the walls, as they are covered. Spraying insecticides around the treatment area might be enough to eradicate them if they are in small numbers. However, in a severe case, fumigation is the only remedy to get back your lost peace of mind. Deathwatch beetles are mainly treated in the same fashion.
