Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Identical to PEG treatment process but sucrose is used instead of PEG solution. The cells of the wood are replaced by sucrose, rather than water. Originally recommended as a low-cost method for treating waterlogged wood, sucrose treatments are inconsistent in how much shrinkage they prevent, especially for severely degraded wood. [12]
Fragment of a broomstick affected by woodworm. Woodboring beetles are commonly detected a few years after new construction. The lumber supply may have contained wood infected with beetle eggs or larvae, and since beetle life cycles can be one or more years, several years may pass before the presence of beetles becomes noticeable.

In practice, a mechanical freezing process is usually used instead due to cost. There has been continuous optimization of the freezing rate in mechanical freezing to minimize ice crystal size. [2] Flash freezing techniques are also used to freeze biological samples quickly so that large ice crystals cannot form and damage the sample. [5]
