I am a self rescuing Princess

And this is my weapon of choice. Bugs in Australia are either venomous or huge or fly. I mean the cockroaches are HUGE and fly IN YOUR FACE. This is the least cheerful of events. So I have an awesome super effective way to combat the bug menace.

1. Run out of room containing terrifying creature (Screaming optional)
2. Retrieve bug spray of justice from area of previous battle
3. Spray the bug, the area around the bug and anything the bug touched
4. Seal the room containing the bug and pretend it doesn't exist for a long length of time
5 - 10. Do anything else
11. Check the room again. Assume is temporarily safe after have turned everything in the room upside down. If find another creature return to step 1
