We contacted the previous tenants, who said they had had bedbugs September 2010, and that an exterminator had come twice for them. The exterminator who came for us said he could tell there had been nesting in the wood construction that our rooms are made out of.

If anyone is planning on moving into this apartment, 4F, we suggest not doing so unless the management is willing to tear down the plywood construction and put in new pressurized walls for you. That may solve the problem, unless the infestation is in the physical walls themselves.

If they try to tell you that the bedbug problem has been taken care of in this apartment, they are lying.
