Well New Jeresy used to be known for Indians and Bedbugs , but now we all know they are everywhere

Its really hard to get rid of bedbugs, best way is to expose them to heat ,

so properly vaccum clean each and every corner of the room, and i would suggest you to throw away the mattress/bed or dry it in the sun for few days ,

i heard its hard to get rid of them even by laundry, but please clean your bedsheets, pillowcases and all clothes with a proper dryer cycle.

and please try to maintain the low room temperature.

and of course let your apartment management know about it. they do spray some pesticides that work for certain amount of time, but these bugs are highly resurgent.

good luck !!
