- spot treatments do NOT kill them. Neither does treating on an apt by apt basis. If they're in one unit, they're all over.

Proof positive? My entire unit had to be dismantled, everything taken out of closets, mattress and boxspring thrown out -
Even AFTER the unit was "treated" by a company the management sent in... the bugs remained.
They are in fact, in the walls, and under the floors coming from neighboring units that were not, and ARE not being treated.

I actually have to be moved out of the apartment and re leased in another property.
Do NOT believe for one second that treating an apt one time with spray will do anything.
They will come back in a few days, and most probably won't even die. They wiggle into cracks and walls and hide there then reappear.

Again, if they are in unit, they are ALL OVER. It's just a matter of time before you have them too.

I have never been more disgusted by something in my life - pray you NEVER have to deal with this.
