I recently discovered that i have bed bugs. My dad is the maintenance guy for our apartment building, and knows that my landlords mother, who lives on the top floor, has had bed bugs for a while, but has done nothing about it to fix the issue. We thought that by spraying bedbug repellent/killer monthly, would stop them from infesting our apartment as well, but after my girlfriend woke up with several bites, and i found several live bedbugs, it's clear that that didn't help. So, does my landlord have the obligation to pay for some sort of treatment for the entire building? Please let me know. Thank you.
