Can anyone help. We live in a 2 bedroom cottage that we have been decorating over the last 6 months. The problem I have is that I have red marks appearing on all of of the newly painted walls and ceilings. they dont appear straight away but are multiplying. I've attached some examples and they are all pretty similar in terms of shape and size. they almost look like crayon marks but we dont have any crayons !
I wish we could help (you dont have kids with a wicked sense of humour and a red crayon do you?!). If it's an insect it's something we havent seen before and the fact that its on the blinds rules out damp marks bleeding through......I really hope someone else can help so we can all know the answer !!
Good luck and please do let us know how you get on..
