Need some help with comp*URGENT*

To begin with this I'm sorry if this is the wrong section.Now, let's begin tomorrow is the 4th of July and I was planning to leave the computer on(for personal reasons :cool) but we do have a bug infestation and my mom bought those fume bombs(I will post picture on how they look). So, now I'm debating whether to leave the computer on with the fumes on will this screw up my computer in any way? Also if I do leave it off will it screw up my computer either way? Is it safer to leave the computer in the back house where we won't be using the fumes?
Here is the picture on how the fumes look

I dont see no possible way this could harm your PC on or off. ed

 

If you are really concerned cover your computer tightly. If you don't have anything thick and heavy to use, use a bed sheet. Do you have something thicker than a sheet? When everything is finished, just wipe everything down with warm water. You guys will have to do that throughout the house anyway. Good luck.

 

Alright thanks guys.

 

DO NOT cover your computer tightly with a heavy blanket while it is running or you may have a dead, cooked computer in short order!

 

And you also might not get the bugs thats inside the case. ed
