#25: Oh, Rats!
If you’ve never smelled a dead rodent in your walls, consider yourself lucky. That smell is horrid, and it lingers forever. No amount of air fresheners will cover up that odor. So, we commiserate with this poor renter over living with that smell for so long. It must have been a relief to finally pinpoint the source of the smell.
… Only to hear the landlord wasn’t willing to do anything about this. Pest control falls under the landlord’s domain; therefore, dead pests are also his responsibility. Come on, pal! You may not like it, but that’s your job. Maybe you should do a better job of keeping the rats out of the apartment, in the first place.
