I've bought ds(5) an old school desk off ebay and the chap delivered it tonight. When it arrived I noticed a group of holes in one corner and asked the seller if it was woodworm. He said he had owned it for 7 years and hadn't thought anything about the holes or seen any more apperaing. Being the sap I am I gave him the cash and off he went.
Now I've looked properly there are about a dozen holes in one small area, then random holes close by.
Is there anything I can treat it with to avoid having to get rid of it and breaking ds's heart. He is really pleased with it and has wanted one for ages.
