Seven Ways to Get Rid of Woodworm

[Chris Garner]

Just to be straight; the life cycle of Anobium punctatum consists of four stages - egg, larva, pupa and adult. Only the larvae cause the damage . As mentioned they rarely attack heartwood, just sapwood.
Ancestors of the species can be traced back to the Permian period. ( 300 - 250 million years ago ) 
Originally found in Europe, it has now spread across the world.
There are many other wood boring species.
