Looks more like woodworm.

Either woodworm or someone's been careless with a shotgun.

Does woodworm make the wood crumbly when poked. What causes this and what is the permanent solution.

The beetle lays her eggs in cracks in the timber. When they hatch they eat their way round the inside leaving all their crap behind and finally come out as a beetle through the flight holes. Damp timber is usually more at risk.
Throw out all the bad timber and treat the area.

Undecided after reading more.

Soluguard or cuprinol treatment.

Water based or solvent based.

Any Advice/Suggestion please what to buy and where without killing my wife and cats in the process.
