Funny you ask, because while people are terrified of mice, bugs are a lot more atrocious to me. They don’t just pop out in a surprise and are gone a second later after scaring you to death, like mice do.
Roaches, especially humongous water bugs, sit on your walls with Chutzpah and crawl around so nauseatingly. Ugh!
As for spraying them, my best insect spray is pure windex. Nothing works better than drowning them in good ol’ windex.
