Embarring "roach" situation... pls help!!!?

I'd go to a garden supply store and get some diatomaceous earth I would get a hand squirt bottle and mix dish soap with water, and them mix in a like amount of the DA. The squirt bottle with dish soap will immediately kill any roach you spray thoroughly , it will leave a slight coating of diatoms which will residual keep kill any roaches it comes in contact with. Yes the most effective thing you can do is to put you pc out in very cold dry weather. and all of the above valuable Equipment. The problem is any eggs or roach do left in those things, which you might take to your new apartment. The mix I gave you is totally organic and effective. Cheap too except for the DA
