Are cockroaches have acidic content in their body somehow?

Question

just now i managed to captured a living cockroach inside a supermarket plastic bag which is transparent.

after i've captured that roach and observe it for a few seconds,the plastic bag somehow melted its like a mozarella cheese melt.

Wherever the roach is going,and theres like a white liquid something came out of its abdomen that makes the plastic bag melt BUT its still unable to penetrate the plastic bag.Sounds creepy though...

Answer 1

dude if u trap a roach inside a plastic bag widout oxygen then obviously it will screte sumthin.....not neccessarily acidic

Answer 2

they have uric acid i think

Answer 3

yeah this is ....this is pretty gross.

maybe it's evolved to secrete acid when it's trapped in something so it can get out!
