High cotton content shirt - 100% will wrinkle like hell, but majority polyester or similar holds odors and looks cheap.

I think some of it also depends upon timing (ie. when the infestation happens/became noticable).In many instances, there's a lot they can do to try and mitigate some of that risk of another infestation happening (ie. sealable, odor containing/closed trash cans, taken out regularly; regular cleaning of the apartment space; ensure food is in tightly sealed containers, even if in the refrigerator; early communication about any standing water or wood rot; wash bedding frequently -  a lot of people eat in bed, and this is an easy way to attract insects and pests because oftentimes most people don't wash their bedding nearly enough).

They might also enjoy knowing that their security deposit will most likely not be coming back to them because removing urine odors generally requires steam cleaning and that is expensive.  

The only truly effective way to remove an odor is to remove the source, be it pad, drywall, or subfloor.

The rodents are are territorial and are leaving their odors of familiarity and do return.They put in a sonic anti rodent contoler in the engine, sprayed strong mint, chili spray, mothballs, set traps To no avail.A landlords lackadaisical attitude can cost you a good tenant with lots of repairs and damage.

You can send someone in now but there's no way to look behind all their stuff and get a real scope of damages, odors, etc.

It was not too bad (dirty carpet and sticky floors) but the smell of trash and body odor was fairly repulsive.

If I were you, I would replace any fabric, ie. carpet, I would pay a cleaning company a couple hundred buck to do a deep clean, change any HVAC filters, then I would go to Home Depot and buy an odor bomb or two.

No harm no foul and move on.
