The most effective method of controlling wood-eating insects is fumigation using phosphine preparations. Phosphine is a gas that is characterized by the ability to penetrate all parts of the wood while causing the killing of all stages of evolution of the insect (egg, larva, nymph, perfect insect).

The application of the method requires proper preparation of the space which requires closing each opening (doors, windows, vents, etc.) in order to prevent gas leakage. Objects that may contain silver, copper or gold should also be removed or covered as there is a risk of oxidation.
