Thread: Borers?

Yeah, sounds like borers .

To be honest and safe, getting it checked out is always a good idea.

Most likely lictus borers - the holes mean you no longer have them. They live and breed in the sapwood only not in the hard wood so they would have arrived when the timber was first used and then departed some time after. Most milling removes sapwood, but some gets through - mostly on edges of the cut boards.

see http://www.csiro.au/resources/pspr.html

which says inter alia:

Treatment of lyctid borer is often unnecessary in the southern parts of Australia. This is due to grading rules in sawmilling which restrict the amount of sapwood contained in framing timbers.
Timber over five years old is unlikely to contain these borer as they will have exhausted their food supply.

So from your description it should be OK - but if you are in doubt you need to get an inspection done.

I'm with bloss they're not much of a problem until u grab a rafter and it turns to dust. he's right they'll be gone by now and they do only eat sap wood it's termites that you have to worry about. the lyctid borer or powder post bettle leaves the saw dust you can see .if you are worried about it there are chemicals you can spray on them but i wouldn't do it because they're not that dangerous to the house
