Just use folded paper to catch them and kill them, then throw their bodies out
I just go to one of our bathrooms ,take some toiletpaper and just..kill it owo"
Just a note- If the cockroach flies, it's actually a bug called a Palmetto bug. They are often mistaken for cockroaches, but most are a lot bigger than cockroaches and have more developed wings, so they can fly.
I hope you survive! If you can, grab a spray of some sort, like a cleaner, air freshener, or just some alcohol in a sprayer, and keep it with you. It may not kill it (MAY not), but if it doesn't it will at least slow it down so it won't fly on you.
I live in the south, so I see these at least once a month -_-* Good luck!
