    My small studio apartment (~500sf) has had bed bugs off and on for the past year. After the first heat treatment, I think we were able to get rid of them, only for them to return 6+ months later, probably from a neighboring apartment. Our entire building has been struggling with this problem, but at the moment, my apartment is one of the remaining ones to still have them, and all my neighbors have either moved out or successfully been treated.
    Early on I sealed up every crevice with caulking that I could find and filled in the cracks with DE in the entire studio. When the bugs returned about a month ago, we have now unsuccessfully heat treated the apartment with temps over 140 degrees for 12 hours or more. The most recent treatment was for the last 2 days only for me to wake up the morning after and find a very healthy adult relaxing on a door jamb. Needless to say, my spirits sank immediately. Luckily, my apartment company owns the heaters and is willing to do it again, but I am reaching out to see if there is something they are missing.

    They are treating with chemical before the heat to catch any bugs that move away when the heat starts up. I have left all belongings in the apartment, clothes loosely scattered, and moved items away from the wall. I really dont have the much stuff in the first place. The windows and doors are taped up with thermal screens to trap more heat inside and keep any bugs from escaping.

    I'm at a loss for what the next step should be. Any suggestions would be appreciated.

    Is the building on a slab with cement block walls? Are they using heat equipment designed for bedbugs? There's a difference between convective and conductive heat.

    thank you for your reply

    The floors are all wood with exterior walls in concrete and i live on the 3rd floor. The building was built in 1928. The heaters they are using are like this:

    They have 2 of these that mate together (seems like one is a fan)and 2 other red ones that are slightly smaller. They run both together for 8 hours a day and just treated my apartment for 2 days in a row. They measure the temp with a thermometer and said it was 140degrees+

    But are the exterior walls concrete blocks? I've been doing this for five years now and have no plans to purchase heat treatment equipment. The wood floors may be limiting the effectiveness of the heat.

    i am not sure of the exact structural components. I know the outside of the building is concrete and it seems to be pretty solid so i would guess by saying that the walls are made of concrete. concrete blocks, im not sure. i think it may be reinforced concrete. i let them know this mornig that i found a live one this morning, literally the morning after treatment. Supposedly, they are up there now respraying the room. Not sure if I'm ever going to get rid of these things.

    Sorry this problem is persisting for you.

    Heat treatment takes knowledge as well as the right method and equipment. It sounds like your apartment management are doing their own treatment. Do they have experience with this?

    Three possibilities (there may be more):
    1. Heat treatment was done incorrectly and did not work.
    2. Attached neighbors have bed bugs. Have all been inspected by a professional since your problem began again?
    3. Other source of continued exposure.

    I started and run the site but am "not an expert."

    so sorry for the late reply. i really appreciate your response. So far I have not seen a bug since the morning after treatment, so thats over a week. I kept him alive in a cup and he died 2 days later. Maybe he was going to die anyway.
    To answer your question, I do think they have some experience with the heat. Supposedly, they had a local expert come in and instruct them on how to properly use the heaters. Im hoping that the one bug i found was going to die anyway and that the spraying that we are doing now will kill off any bugs that remain.

    Thanks for putting up this site. It was helpful to read about other people's experiences.
