Mutant roaches…

They fumigated our building a couple weeks ago and since then our apartment has had tons of roaches and they’re all like the size of dogs!!! I just had one in my room and we’re out of bug spray so I had no way to kill it but my 13 yr old brother came in, squished it and saved the day…:0) Whos said theres no point to the males existing? Who else would squish the cockaroaches???
