Can you freeze an oil painting on canvas to kill termites in the wooden frame?

Yes, you can freeze an oil painting on canvas to kill termites in the wooden frame. However, it's important to ensure that both the painting and the frame can withstand low temperatures without damage. Typically, freezing for at least 48 hours should be effective in killing the termites. After freezing, allow the painting to return to room temperature gradually to prevent condensation and potential damage.
