Woodworm in old chair - treat or get rid?

[Devora]

So I got an old chair off Ebay and am very pleased with it. But have a number of times noticed fine sawdust underneath. Presumably woodworm?

I also bought some kitchen chairs from a closing down restaurant the other day, and have repainted them. Noticed that one of them has a number of small holes. Woodworm again?

I have wooden floors. Should I just get rid of them or is woodworm easy to treat? If the latter, what is best to use?

You have brought woodworm into your house. Now your house is infested.

If you are going to buy old furniture, you had better treat every item and let it dry before you bring it inside. The floor and other wooden items near your wormy chairs also need attention.

If you have good central heating and do not drape wet washing then it is possible the humidity is low enough to make life difficult for them.

p.s.

I use Cuprinol which you can get from DIY sheds and builders merchants.

Aaagh, PigletJohn says I am doomed

I do indeed drape wet washing. Right near the infested chair.

OK, I'm off in search of Cuprinol. Kicking myself.

Small holes mean there's been woodworm, as they've chewed their way out, so could be ok now, although I'd treat it anyway, and every area nearby. As I remember, other creatures gnaw and leave sawdust, but safest to treat that too, and wooden floor (can't remember what we used in old house, but PJ's probably right with Cuprinol.)

All the wood is varnished - will the treatment work with that? Will I need to revarnish?

My entire house is furnished from Ebay and carboot sales - it never occurred to me to check for woodworm [idiot emoticon]. Ah well, lesson learned...

For painted and varnished wood, you can get wodworm killer with a fine nozzle to inject it into the holes. It will be quite messy so do it outside. Brush onto the back and underneath as well which are probably unpainted.

this is the stuff with the nozzle

if you have bare timber and can brush it on, this or the Cuprinol one work out much cheaper in a big tin.

Poisonous (obv) and flammable, so use plenty of protection and do it outdoors.

You will also see water-based preservative stains for fences, these are waxy and do not include insecticide, so no good for woodworm.

You are a one-man marvel, PigletJohn. If you ever change your mind about that marriage proposal, let me know.
