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.
Hard to tell from the picture but reminds me of roach excretment.
Check inside the hinges of kitchen cabinets and let me know what you see.
Also look behind the stove.
It doesn’t look like mouse droppings to me. Mice leave feces which are like small grains of rice. Their droppings are well formed, not runny or misformed.
Thanks everyone for your help. I’ve heard that these might also be fly droppings?
Each cirle in each group is about 0.3mm, and are slightly raised (when on a solid surface) - I’m guessing that they’re liquid(ish) when made and solidify over time.
Another possibility I’ve read today mentions what’s left when a fly regurgitates what it’s previously eaten to re-digest it, and then gets disturbed and flies off.
I think the BB may have hit an all time low. Educated and experienced HIs analyzing and seriously discussing rodent, fly and bug $hit. Did you try tasting it?
Actually, it looks like bat guano and sounds like it from the description. They go in the same place each time they leave their roost. Too big for insect and too liquid for rodent.
