I have no idea but maybe take a bottle of Avon Skin So Soft dry oil spray, the green one. It's fab. I had it with me on holiday a couple of weeks ago and I only got bitten on the one night I forgot to put it on.....grrr
oops sorry I didn't reply earlier thanks It's actually for ds as he got so badly bitten once at Het meerdal, when he got back to school his teacher thought he had chicken pox. He has been okay at other CP but Eemhoff looks like it has a lot of water. Avon are online now Portofino so you might be able to get it from their website.
