Give them a heads up before doing treatment with what the pest guy says needs to be done,, trash, put food items in plastic containers,, ect.If they don't comply give them notice to move, non- compliance with terms of lease, cleanliness. this could infest your entire building, and I would have pest guy treat all neighboring apartments. 

Peanut butter on glue traps, check the traps daily or you will hear the little guy fussing and fighting to get free, use a plastic shopping bag or two as a glove to pick up and wrap in the glue trap with mouse still on it in the bag and tie that in a knot, then proceed to step on him or give him a fast swing and slam on the side of the trash can, then dispose of the dead vermin.The poison, is not always attractive bait and then they can die in your place and smell, or be eaten by other animals that we don't want to kill(owls, bobcats, pet cats and/or dogs)About a dozen kills to my credit.

id=DOC_7399.docHere's a transcript of the document:Sample letter for Companion AnimalDATENAME OF PROFESSIONAL (therapist, physician, psychiatrist, rehabilitation counselor)ADDRESSDear [HOUSING AUTHROITY/LANDLORD]:[NAME OF TENANT] is my patient, and has been under my care since [DATE].

Newer Houses will have plastic which won't corrode.

You need a dog for a companion tho.

And tell them if they want to keep the dog, they will have to get a note from their doctor saying it's needed as a companion animal for their disability, and they can keep it.  

They gave me a large plastic bag what holds 50 lbs of quarters (it is some sort of security bag), I weigh out 50 lbs of quarters, fill the bag, drop them off at the bank about 3 times a year, they credit my account $1,000.

All are plastic wheeled carts, and you have to roll them like 15 feet to the curb by 6am on collection day, and take them back at the end of the day.I have tried various approaches with mixed results.Allowing it to overflow results in trash being thrown into the wrong cart, or stacked outside, attracting possums, raccoons, squirrels, lizards, stray cats to rip them apart and cause a mess.Do you leave it to the tenants to work it out on some rotation schedule?  

It looks in decent shape, has 4800 miles, but has scapes in the plastic on one side where it looks like it was dropped.

Before I agree to rent to anyone with an animal(companion, assistive or pet, I meet it to make sure it is not overly aggressive.
