That’s 55 Celsius. Doesn’t sound too bothersome. What if they hide somewhere? Does 130F/55C just kill them at once?

It's not immediate, but my crude understanding was the heaters they use are positioned so the outer edges of the home heat up first. That way the bed bugs can't escape - they'd have to know to go towards the heat first.

Also don't forget it just takes time to heat up a home that much.

Wouldn't that damage stuff? Plastics will go weak and start outgassing. Electronics might break.. and if you move all that stuff out you might take them with you

Among the instructions you get are to put batteries and anything sensitive to heat in the fridge for protection. I didn't notice any damage after I had it done; my laptop, robot vacuum, and smart switches worked fine afterwards.

They die due to dehydration. They live on blood. Dead one are just flat. I have cought some and left in a sun in a cup. They died in a day or two.

If they are not hungry, they will stay at one location. When they are hungry, they will travel.

Typically they like to live near their food sources. In hotel, they are found in Mattress bedframe etc. High heat has high fan running too. As long as air reaches their, it will heat up. We had 100% success rate with heat as long as you setup properly
