I had a mouse infestation in a kitchen once and they pee all over to mark their territory and to help them navigate because of poor eyesight.

Then I would amend the rental agreement to put more responsibility onto the tenant for maintaining it that way and for notifying me in a timely manner if a re-infestation occurs.

Clean up the rotting food (to prevent damage and bug infestation) in any case. 

Hello fellow Wyoming new infester. all I can say is good luck!

I ended up dumping the properties; however, because learned from a local that the specific neighborhood the units were located in was heavily infested with drug activity, mainly meth and heroin.An investor from the area purchased them with full knowledge of the situation.  

I have said it before lower end SFR the tenants live hard in the units and tend to have lots of life issues which they tend to take out on inanimate objects.This also applies to mid level to crime infested QUADS.   

The tenant they interviewed says her house is infested with rats, mice and cockroaches.

A house with a lot of promise and character has been overwhelmed by cat feces and was also condemned by the city due to roach infestation.

This place is infested with sharks...................watch out! 

One we had, we honestly suspected of dog fighting, and when he  left-- he left is roach infested-- no one talks about those types of military experiences, but they are out there!
