If the home has a garbage disposal in the kitchen I would remove it.

There may be an initially higher cost to get the current infestation under control, but then going forward, it should be just the regular monthly charge.What I'd do, is give the tenant written notice about how you are taking care of the infestation - that you've hired such and such company, details about how they are dealing with the infestation, and how they will be treating monthly going forward, and enclosed is the information the company provided about how the tenant needs to clean up food laying around, and take the garbage out regularly, etc.  

Wait till the political election train begins again and the garbage will fly and what was and wasn’t done.  

Yeah, she ended up kicked out because she couldn't make rent a priority and the previous manager let her get away with this garbage for years.

Lots of lawyers sign em (hold harmless waivers) without ever looking because they know they are garbage.

This may sound goofy, but if you provided something which contains pictures of the apartment before move-in, model numbers of appliances and links to user manuals online, information on how to use the thermostat, locking doors & windows, operating faucets, garbage collection guidelines, contacting the HOA or property management company, what brand and color paint you use in each room, etc.

Sometimes if I'm on the fence regarding renting to a tenant, I'll drive by where they currently live... if they're living in a run down place or if there's garbage, etc outside, that's an indication of how they live and will treat your property.
