Abstract: A wood protecting agent, particularly for the protection of wood against dry-wood-destroying insects is provided. The wood protecting agent comprises a wood preservative carrier and the combination of at least one insect juvenile hormone or its analogue or mimetic with at least one an ecdysone agonist or its analogue or mimetic in a concentration of 0.5 to 0.00005 % by weight, related to the entire formulation, and optionally, one or more triazole compounds to achieve a synergistic increase in effectiveness of said formulation.
