Viral posts circulating on Facebook for the last two years are warning people about the dangers of insects and insect eggs in their Christmas trees.
Festive fun is being put on hold as people warn that what looks like a pine cone could be a nest of 200 preying mantis eggs.
And, while experts say it is possible, they also say it is highly unlikely in the UK.
The original post shared in 2017 was from the USA, where preying mantis are native, while the trees we use in the UK tend to come from this country or from northern Europe - where you won't find any mantis eggs in your tree.
Experts say there will potentially be thousands of insects in your Christmas tree, but they are absolutely nothing to worry about - and there are steps you can take.
Alan Stubbs of BugLife - the British Invertebrate Conservation Trust - said: "A tree grown outdoors, and then brought indoors in late December, may carry invertebrates awoken by the warmth, and eggs hatch, but one would have to be pretty unlucky to become aware of emerging creatures.
"If eggs hatch, the newly emerged young are very tiny and inconspicuous, and the tree will be out of the house again too soon for the young to have grown far."
He added: "As yet no preying mantis species has been able to establish as a breeding species in the wild (despite opportunities)."
Alan says the best course of action is to make sure your tree is grown in the UK - so any bugs and other wildlife that it carries will be native and therefore mostly harmless.
He said: "Britain has been pretty lax over import of plants and trees, hence the number of plant diseases and pests that have come into Britain.
"Ash Dieback has been a case in point."
So according to the experts, even though there are likely to be bugs in your tree, if it was grown in Europe - and even better the UK - they will be of no risk to you and you are very unlikely to even notice them.
If you haven't put your tree up yet, before you bring it inside give it a good shake, knock the base of the trunk on the ground a few times, to make sure anything loose comes free.
Happy Christmas!
