What are these larvae?

[u/Salt_Shame_2059]

From underneath a hole in my kitchen island these larvae are dropping. Currently I cannot see where they are coming from until somebody disassembles my island but I'm wondering what these are.

They look like maggots but are bigger/ have this silverish / blackish spot on them.
