Question re: Keith putting sugar in walls

[iheartnihilism]

My landlord is a fucking asshole. I'm not going to elaborate, but take my word that he is an asshole and i'm not saying this for some bullshit reason like "he yelled at us when we had a loud party".

So, my question, how soon would bugs show up if i put sugar in the walls? There's a small hole in the wall in my bedroom (cause by the plug in the back of my computer - thin ass paper walls). The problem is, while I'm moving on 6/29, because we gave him late notice, we have to pay rent through july. The hole needs to be plugged by 7/1, but i wont get my security (or part of it at least) until we have "vacated the premises" (august 1st.)

If i can't put sugar in the walls, what else can i do that won't show up for a month? Because i have to do SOMETHING.

Edit: It's a two floor two family house and we have neighbors downstairs who I'm assuming will still be there after we've gone.
