I’ve been involved in looking at the interior of a house where black spots keep regularly reappearing…
They look like something dropping or sprayed, as they are always on a horizontal surface (floor, cushions on sofa, etc) and always seem to appear in small groups, perhaps up to 20 or so in number.
On the laminate floor, they appear as slightly raised black dots (I thought they might have been some insect eggs at first) but on fabric, they seem more like a liquid that runs into the fabrics threads.
They are easy to remove/wash out, but are continuously re-appearing in different places around the property, and I was wondering if anyone has come across this before and knows anything about it?
I’ve included a photo of some of the dots, which may help with my explanation.
Thanks in advance!
