It's like in the show "Breaking Bad" where they have a pallet of money in a storage unit and the wife goes in to spray so the bugs don't eat it all.

Call Terminix and have them come spray the house for like $130 or so.

I started by rolling but had to use a brush to paint the groves - I gave that up after priming and sprayed the rest fairly quickly.

I also always carry pepper spray.

The sink base cabinetis broken at the bottom.ApartmentConditions33 The Tile shower surround has failed and has loose tiles and mold, thebathroom entry door will not close, the floor tiles are lifting due tomajor moisture damage to the sub floor, the faucet is missing anaerator and sprays water everywhere.

Takes the pest control guy to come spray a couple times and its good. 

Mix with water and spray it on sheetrock and let it dry before painting.

Then, everything that remained anywhere near the fire was sprayed with a sealant to contain any smoke odor.  

I also have exterminators do outside spraying but nothing inside.

I have one tenant keep reporting bed bugs, approximately every 2 months.The first time, we sent pest control company, the company found there are few bed bugs in the sofa and did the spray.
