That looks like the ash borer ........and if it is it a huge problem ....I dunno if it in this country but in the states it's a huge huge problem up north

Ash bark beetles (Hylesinus fraxini) are very common on felled timber. If the central maternal gallery (5-10cm long) is twice as wide as the offshoot larval galleries (2-5cm long), then that's a sure sign. They're native to the UK and pose no danger to your timber.

great diagnosis. Thought as much. Thanks all.

Ash so infected with Ash Bark beetles, is it sellable?. Does the frost kill them, I assume it should. Are they dangerous within properties as in attacking the timbers within the property?.

 

Not actually ever seen any as such but no doubt I will sooner or later and need to be prepared.

I had a load of ash given to me with loads of i think are woodworm holes, The ash was outside for 18 months stacked up.I was concerned about selling due to the holes but was informed that the only time the larvae are present is between the months of may and june . And the holes are where the woodworm makes its way out Is that correct ?
