I’ve sprayed and that doesn’t work so I’ve resorted to using Terro gel.

I had to replace two exterior walls and spray it with borate.  

Took 3 visits myself and 2 of the plumber to find a pinhole leak that was spraying out a copper pipe.

That would include providing furniture the same way that if a refrigerator or pest control spraying twice a year was listed as being included, they'd need to provide those too. 

We currently use Petscreening.com which is a free service to Landlords and really saves time.Things we want to look for:Age, size, breed, etc.Rental history with the animal, good reference from previous LandlordPicture of the animalVet recordsTenant must also sign an affidavit stating there is no bite history, the animal has no destructive tenancies (digging, chewing, spraying, etc.), the animal is leashed and/or under their control outside of the property, they accept responsibility for damage and will immediately correct it, owner will clean p after the animal immediately, etc. 

I haven’t seen food left out in either unit, they are generally pretty tidy.I’ve sprayed the perimeter of the building with rodent repellent, and have laid out baits and traps inside.

I’m just going to offer up the chemicals and if he would like to get up there and spray himself I’ll be more then happy to give the chemicals and tools.

But don't know if this device is over-kill, for spraying down places in buildings, where rats are expected to be, or have been.

If you paint first, you protect the other finishes (and can spray, which is quicker), but then you have to touch-up afterwards. 

I had the house sprayed on Monday and the exterminator said I’m getting bugs because the house is “very porous”.
