Bed bugs sit around the bed more than in it: frame joints, slats, screw holes, behind the bedhead, the skirting gap, the seams of a chair nobody moves. Bites in a line, small blood spots on the sheet, dark specks in the joints. The whole room gets treated, and it takes two passes, because nothing on the market kills the eggs.
The second visit at roughly two weeks is what finishes it, timed for what has hatched since. Keep sleeping in that bed in between; moving to the couch moves the infestation to the couch. Bagging and hot-washing at 60 degrees then running the dryer hot does more than people expect. Share-house and student rentals near Deakin get checked room by room, plus the rooms either side.
