Cockroaches

Rithi,
This is problem for which ur apt magmt is responsible as this is endemic to USA and they need to do an intensive pest control. Talk to them abt it and they should be able to do something more effective like a stronger treatment and if you're outta town then ask if they can do a 'fogger' treatment which fumigates the whole place up and is quite effective - plus do a regular pc every week for a couple of months and keep the apt mgmt informed as the roaches could be coming from neighbouring apt/s also & you cant do anything abt it....so if its really a big problem involve them rather than struggling with ot on your own.
:cheers
