I stayed in an apartment that was infested with roaches and they followed us when we moved out. They started to try and establish a colony in the new house we were renting but we waged a war on them. We bombed the house with bug spray, foggers, and diatomaceous earth but it was still a struggle getting rid of them all. At one point my computer was getting dusty so I decided to clean it out when I noticed that a pregnant roach had kamikaze'd head first through a case fan. Her upper body was completely torn to shreds but she had managed to make it inside and laid her egg which hatched and dozens of babies lived in my computer. I was equal parts horrified and impressed.
