insects on felled ash timber

[Alycidon]

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 ?

 

As I understand it yes.

Not quite, I'm afraid. Woodworm larvae take a number of years in there before they come out (5-7yrs from memory) and they emerge in the spring - so March through May or so.

 

It's a good reason for not keeping logs indoors past the winter, even on display. And why display logs are treated.

 

Woodworm goes into the heart wood - if I see any it's almost always in wood that's a bit rotten and is destined for the bonfire anyway. Or if it's a bit sound, I burn it myself.

 

Ash bark beetle never goes deeper than the bark - lots of holes in the bark, but not in the heartwood. Only one customer has ever mentioned it to me - he kept his logs in the conservatory and they flocked to the windows and died - but he wasn't bothered. He just hovered them up. But for the 'posh' customers, another good reason not to keep wood in the house for long.

Thats great info thanks for that , The holes in my ash are just in the bark so not a problem then.
