WTF IS THIS WORM THING

Hi So I found these tiny little worm things in my coffee frother - I didn’t use it for 2 days and then opened it today to see this nightmare

I have no idea what these are and how did they even GET in the thing

I’m assuming these come from some sort of eggs but I wash this thing immediately after every use then dry it and only then do I put it away to be used the next day

Can anyone please help me identify whatever this is

I’m going to submerge the entire thing in boiling water then scrub it clean by opening the entire thing and deep clean through the screws and all

Should I just throw it away cause is it harmful? I’m feeling very very icky because I love using this for my coffee and I am just feeling yucky know there’s these tiny little things just worming around there They’re inside the cup too😭😭

Can someone please help
