Woodworm Life Cycle

An adult female woodworm likes to lay eggs on or under the surface of a wood in cracks, pores and crevices. While it is safe inside a timber, the larvae continue feeding on wood for several years.  This causes the damage until they pupate and then, hatch as beetles. 

Once they have reached their maturity, the newer generation of beetles will be leaving the timber in order for them to breed.  The female adults may have already found a suitable wood surface where they are about to lay their eggs. Then the life cycle will continue which causes further damage.
