Tenants moving out due to roaches

[Paige Roberts]

My tenants called today informing me they are breaking their lease and moving out.  They moved in around February of this year.  I had the rental professional sprayed before move in.  A 3 or so weeks after they told me roaches were there.  I called pest control immediately.  They sprayed. They said they woild need a follow up in two weeks. My tenant went into premature labor and was gone for a month. I wasn't able to do the follow up, i even askerthe husband tenant while she was in the hospital if we could spray before the baby got home. He said he wouldn't have time.   They get home and of course the roaches are back.  I called and the pest control came yesterday.  They had been staying at a family's place while it was getting taken care of.  They haven't even been back to the rental since it was sprayed when they called me today. I told them I understood and they demanded their rent of June back and deposit. I told them I could not give deposit back bevause I've noticed a lot of things I'll need to replace last time I was in there.  Am i doing the right thing by giving them all of this month's rent back and no deposit? I don't understand because I tried to rectify the problem as much as possible by being on top of it and calling as soon as I knew.  Thoughts on the whole situation? I feel horrible about the roaches.
