What are these??

[Frazzled13]

I just found a handful of these under the bookcase we have in our kitchen/dining room. I thought they must be mouse droppings but then I squished one and it was like a white goopy liquid inside so I guess not?
Are these a sign of some horrible animal infestation? I can't for the life of me figure out what they might be?
We don't have any pets, DD is 14 months so makes quite a mess when eating but I can't think what food might go like this is left under a bookcase accidentally for a while? I'm pretty thorough about cleaning up after her so I'm really hoping I haven't attracted mice or something!

mice or rat droppings.
how big are they? mice ones are absolutely tiny.

Oh no, really? With the white goop inside? They are maybe grain of rice sized, a little smaller. And they are only in this one place, there are none in the kitchen or anywhere else that I can see.

Is it fly pupae?

They are pupae not mouse poo. So the goo inside is the developing creature. Not sure on what pupae though, could be a fly , or a beetle of some sort.
You don’t have mice OP. 🙂

(not envy) I've never noticed a particularly large number of flies, (just a normal amount coming in through open doors in summer), and I've never seen any beetles or anything. Can I just clean these up and that should be the end of it?

I mean, they aren't a sign of some infestation I'll need to get sorted?

Yes you can just put them outside somewhere. All houses have insects living in them too, unless you have a lot of them appearing it isn’t an issue at all.
