Alabama pays their players better and they have a better benefits program, not limited too, but including Deer Antler Spray and Dodge Charger Hellcats with a trunk full of $$$$$ upon delivery.

Mix both the 1 year pre emergent and the All kill and spray together.

I also worry that the urine/crystal are in the walls and maybe even ceiling since cats sometimes spray.

We hired a professional company that inspected the entire building and sprayed every unit where he found infestations.  

Your tenant might want to package his trash differently for the intruder's personal enjoyment...maybe duct taping all the bags closed, maybe spray the bags with WD40 so the poor sap doesn't get that sack ripping burn, or a gift tag on every bag saying "I see you."  

If the odor is from cats, they will often spray on walls and the urine drips behind baseboards, so you have to pull those as well.Rack up the charges, then send the departing tenant a bill.

I did not sand the cabinets and it worked just fine....however YOU HAVE TO spray it on and not use a brush/roller.

Spray foam insulation and very comfortable. 

This is five minutes to mix up and apply some Durham's Water Putty that costs ten bucks a can, then sanding after it dries and a touch-up coat of spray paint.

Spray it with bleach and clean with soap and water.
