Treat Bed Bugs

Is it the landlords responsibility to take care of bed bugs when it is the tenants who have brought them into an apartment.

When I was renting, every apartment complex I lived in had a monthly pest extermination. It is the landlord's responsibility to keep the units pest-free. There is no way to know if a tenant infested the apartment because pests can move from one unit to another. That would be a tough case to try.
