This isn’t good, is it? Sorry the photos aren’t the best, I didn’t want to get too close. I pulled off one of the baseboards in my apartment. I’ve only been here a month and a half, and I thought my dog had had an accident on the floorboards, but now I’m worried it might have been roach smell… I’m sending the photos to my landlord, but I wanted to get an opinion about how bad it is, and how I should clean it up until the pros come. Thanks!
