Advice on lease language regarding rodents

[Tom McGee]

Looking for advice on how landlords handle pests and rodents in lease agreements. How do you structure your leases regarding tenant - landlord responsibilities?  As a landlord, how specific do you get and at what point, if any, does tenant become responsible fro treating the issue (other than communicating to the landlord of issues). 

I realize laws change from state to state.  This is a Pennsylvania question.

I have just in the past month added a paragraph stating that the tenant must supply and use mouse traps, cockroach poison, foggers or other pest control products that are readily available in grocery stores and DIY supply stores. They are to read and follow the instructions. Contact me if these steps do not adequately solve the problems.
