If moving to a new home and bedbugs are already present, likely this home has been treated with chemicals. Bedbugs are immune to most chemicals marketed to kill them. A bedbug will live in one place, often on a mattress. They'll mark that spot with a pheromone feed and return to the same spot. A female will lay 1-5 eggs daily. Over time the colony is made up of varying ages and developmental stages of bedbugs all living in the same spot. When chemicals are used, the members flee and spread to different areas, often taking refuge in the walls via the outlets and fixtures. Once in the walls they become more difficult to treat.
If I were moving in, I'd find a heater rental. I'd empty and dispose if all moving boxes, cardboard insulates and protects from heat. If they're in the walls, you'll need to heat long enough to have the heat pe*****te to their colony in the walls. Heat kills 100% if you get to kill temperature where they are. They won't flee and once it's cool, it's safe for your family.
Think of the home like a baked potato. A potato has mass and your home has mass. If you put a potato in the oven at 500 degrees, it would burn on the outside and be raw and cold on the inside. Instead, you bake the potato at a lower temperature for longer. It's the same with your home heat at a lower temperature for a longer duration. Three different studies I'll site. One says all stages of bedbugs, including eggs, die when 113 degree temperature is held for sixty minutes. Another says two degrees hotter, 115 degrees, all stages are dead in seven minutes. The third says they've been known to live up to 122 degrees.
Preheat your home by setting the thermostat as high as possible.
One strategy, rent one heater for an extended time, moving from room to room and back, bumping up and maintaining kill temperatures in each room allowing time for heat to pe*****te and reach deep into the walls and structure.
A second strategy, same principle, rent multiple heaters (based on the electrical capacity) and do the same thing.
Use sticky traps to determine if any area needs hit again.
