Mysterious sand-like piles appearing in garage

[tunnocksreturns2019]

What is this stuff? Tiny spider mite eggs or something? Yuck! What should I be doing about it? It appears overnight every night :-/

I'm assuming you don't have Sand in the garage OP??

Could it be very fine sawdust from something like woodworm?

Do you have wooden rafters in the garage or wooden boarding? If you do then maybe check it for something burrowing into it?

Do you have ants? We get that in the garden where the ants come up through the paving.

Teeny tiny vampires who stayed out too late.

Woodworm?

Thanks all. I was out at church obviously praying about the situation

I think ants is on the money. There’s no wood around to gnaw.

Or vampires.

If it comes back every night then less likely to be ants - I agree with something falling from wood/ holes in wood from above. Ants burrow but you can usually see small holes close to their digging where they go in and out and there's more of a mix of colour in the heaps unless they are digging purely in sand.

I don't see how if can be ants if it's not on joins or holes on the flooring though

Ants? Or a wooden ceiling being destroyed by woodworm? I hope for you it’s ants.
If I were you I would put an ant trap in the garage and see if the mystery piles disappear.

Frass if it’s coming from above. Ants if it’s coming from below.

If it were ants burrowing downwards through the grey floor wouldnt the piles be grey?

Hmm. Ceiling isn’t wooden. It’s not wood. It smells…weird. Kind of sickly.

What is the ceiling made of?

There seems too much for it not to be something sawdust or sand like. It can't be eggs of any kind - you'd have to burn the building down!

Golden caster sugar?

It’s definitely not sawdust. Or sugar! Walls are painted concrete, ceiling is painted plaster, all is oddly immaculate for a garage as I’ve just sorted it out.

It’s mostly appearing on the gaps between floor tiles…which are on top of concrete.

The grey tubs nearby contain chicken food. It’s also not spilt chicken food.

I’m wondering about spider mite eggs. Spider mites being a common chicken issue.

If so it’s getting cold soon so that will be the end of that.

It’s not something inanimate. It’s inherently a bit creepy
