Kids across West Dunbartonshire are being warned not to go guising this weekend in a bid to minimise the risk of spreading coronavirus.
Deputy First Minister John Swinney says the move is necessary to ensure people stay within the current restrictions on indoor and outdoor gatherings.
The government has instead shared ideas on how to have fun at home.
Mr Swinney said: “The safest thing to do this year is to stay at home. I know guising is a big part of Halloween and children will be sad to miss out, but as door-to-door guising brings an additional and avoidable risk of spreading the virus, our clear advice for families is to avoid it.”
Families are also being asked to ensure they are being safe and responsible if they plan to have fireworks in their own gardens in the absence of organised displays.
West Dunbartonshire Council cancelled its regular displays which usually take place in Levengrove and Dalmuir parks.
The advice comes days after Scots were urged to get ready for a “digital Christmas”.
Jason Leitch, the national clinical director of the Scottish Government, said in an interview: “Christmas is not going to be normal, absolutely no question about that.”
He told BBC Scotland: “We’re not going to be in large family groupings with multiple families coming round that is fiction for this year”.
“But I’m hopeful that if we can get numbers down to a certain level we may be able to get some form of normality. “But people should get their digital Christmas ready.”
”I want us to be able to celebrate Christmas as normally as we are able to do within the context of a global pandemic but the message I have is that the more we stick with these difficult restrictions, the more chance there will be of us doing that.”
She said: “We’re unlikely to be able to celebrate Christmas with no limits to the people in our houses and no limit to what we do but the more we get the virus under control, the greater chance of having some ability to interact with our loved ones.”
