What are these marks in my loft?

Tidying up in the loft the other day, I noticed these… it looks like brown drops (mostly) all over the insulation. It’s mostly in one quarter of the loft rather than spread all the way through.

Could it be condensation that has just picked up dirt from the roof, or is it something a critter has left behind, or something else?

Sorry for the huge pics!

That is absolutely Vivid Condensation caused by 5G masts.

You need to burn the house down now basically.

Its where the Chemtrail gas has permeated your loft and burnt the insulation. Good job you had insulation as it has insulated you for the effect but, yes, you should burn the house down and obviously all your neighbours will have this.

Burn their houses down too. They will thank you for it.

It’s blood spatter…

The most likely explanation is that it’s condensation dripping from the sarking felt, coloured by the tar in the felt. How damp does it feel and smell in the attic? Is it well ventilated under the eaves? You don’t have any bathroom extractors venting into the attic, do you? Some do!

Did you put the insulation in recently? If you did, did you leave gaps at the eaves? Blocking the eaves can block ventilation.

The brown marks on the plastic looks like condensation drips from the felt

That looks like drop bear urine.

It’s been nice knowing you

Have you checked the loft carefully?

bats? please

don’t

eat them

Dare we ask who you’ve disposed of in the white plastic bag?

Condensation from the felt. Most likely over/near the loft hatch or bathroom, especially if your ceiling has no vapour barrier.

Could be else where though, depending on wind pressure and ventilation.

Checked for bats, I had the slow cooker ready but unfortunately couldn’t find any up there.

I would love a friendly bear in the loft but no sign of that either.

Thanks for the replies though, good to hear it’s suspected condensation rather than anything else. I’ll check the insulation and the eves (none of which are recent) this weekend and check the extractor pipe from the bathroom which does indeed run through there.

Phew!

I would love a friendly bear

You don’t know what a drop bear is so you? It’s Australia’s apex predator. Not friendly.

The pattern looks too linear to be a critter. I’d suspect something dripping – condensation, mass murderer, that kind of thing.

I’m favouring the chemtrails, although those will be fairly old, there aren’t any chemtrails to speak of at the moment. If there are fresh ones, well, you could be harbouring a dropbear – I understand they’ve been finding their way out of Australia due to the wildfires destroying the trees they hide in, and loft spaces give them close and easy access to human heads…

Check during heavy rain too. You may have a cracked tile/slate.
