Whilst away in Cornwall, the last two weeks, we noticed small dots appearing on our bed sheets, there were several flies buzzing around the caravan could they be the culprits. By the end of the two weeks there were several areas dotted

We had the same this week though not as bad, about a quarter of that amount. Odd that they form in clusters. We saw vey few flies. Other years we have had thousands and no spots. The following day they had mostly faded on their own.

Perplexed.

They could also be Spider droppings, any sign of a spider above,

No spiders around, I have had problems with spider droppings in aircraft hangers.

We also found a couple of droppings on top of the door waste bin. Never noticed this in 18 years of caravanning, we see specks on windows at home, but nothing in the van for the flies to eat from, except for some oranges.
Everything else as normal. Eventually found where I had stowed the Insect spray, on the last day.

Have spots like those just on things in the Garage ,where Spiders seem to love to live. I have Aerosols to get rid of them which I have to use regularly. They also get around my security camera and lots of these spots directly below.
