Clusters of black dots appearing on work surfaces

[Lund]

Hi all,

I keep on finding clusters of small black dots no more than 1mm in size appearing on work surfaces in the office and kitchen. Please see the attached image below.



I have posted in All Creatures Great & Small as I'm sure they may be eggs or droppings of some sort! Any ideas?

Cheers,
Lund

Fly crap?

Is there a spider's web somewhere above it?

Get a pencil and join them up.
Then you will know what it is !!

Possibly.

It's a farm house so more than likely!

Brilliant idea, I never thought of that!

It's really nothing to worry about.

There were three similar cases in isolated farm houses in Siberia last month. The dots grew and grew, joined up and then...








You'll be fine.

Cheers, more than likely. There are thousands of flies with it being a farm!

It is fly st

Apparently it’s news to some high quality publications that spiders crap in the house - do you think we should tell them about the bears?

That worktop is flyblown.

We have been having these same patches as per the OP's photo begin appearing and it is really annoying. There are no flies in the house, that we can see. (my wife is quite keen on murdering any fly that dares enter the home).

They always appear in the middle of the hallway floor, in a similar place each time.

Do flies really crap that much to leave a 2-3" wide patch of st in one sitting?

My wife similarly murders any fly that enters - she has a thing that looks like a wire strung tennis racket with a battery in the handle.
I just open the window and let them out. She swears it's fly poo.

My best guess re the dots is spider poo. We too live in the country and have plenty of spiders in the house. The dots are concentrated into small areas
Spiders tend to stay in one place, flies fly around.

Yep, spiders

I solved this problem many years ago before the internet was born. A closely-spaced collection of small droplets. Look up. Oh yes it's a spider.
