Tiny bit of moth evidence

[LanaorAna2]

Found on brother's 'new' coat via the charity shop. We don't want to bin coat as it's otherwise in v good nick, still with tags.

Any suggestions for keeping it? I've applied acana moth spray to the offending area and Febrezed it vigorously, leaving it to get nice and cold outside.

You could try freezing it in a bag for a few days (weeks? not sure, google it!) I think that kills any eggs.
If you can avoid having moths I would do so! We've got them and I've just accepted that it's a fact of life. They seem to have eaten all the things of ours they wanted, some woollens they aren't keen on for some reason. They must be eating something, they whizz around at bedtime and catch your eye in an annoying way.
