How do I remove rubbing alcohol stains from a wall?

Rubbing alcohol does not stain. If it dissolved the paint, well, you have shiny spots now.

You really should learn a few things before you burn your house down. Alcohol burns, and it is not the recommended treatment for bed bugs. And how do you know you have bed bugs? They are not usually found on walls. The treatment for bed bugs, and a good choice for unknown bugs, is diatomaceous earth. Go to any hardware store and ask for "d.e." and also get the sprayer for it. It is totally harmless to people and pets, but it grinds bugs to pieces.
