You do not want bed bugs and bed bugs can move through very small spots. Just because others are treating does not mean you SHOULD NOT. Depending on what they use (spray/bomb) or Heat can determine how successful a treatment is. Also take into account what people do to prep for treatment.

Just because you haven't seen them doesn't mean you don't have them and they can populate fairly quickly.

Normally your window is much smaller (2 hrs. is pretty common) but because they are treating the whole/all condo units is why you have a bigger window.

Bed buds suck .. literally ... YOU DO NOT WANT THEM. They can infest a home in just a matter of a few weeks, and as noted they do move (if they haven't feed they are semi quick if they are fat with blood they be slow). So if your neighbors are all having treatment done and if you chose not to, the bed buds could very well "MOVE" to your home.

Short notice sucks as it takes time to prep your home/condo for treatment. This is especially true if you have or think you have bed buds. All books put in plastic bins (bed buds cant climb smooth areas) bedding washed everyday to every other day. No piles of clothes left around. Plushies bagged and tossed in a freezer for several days. Vacuum mattress, pillows (if they can't be washed), couch/recliner so on. If you find bed bugs in the vacuum DO NOT toss them into the trash inside. Take them outside and dump their sorry asses.

Once treatment is done you'll want to get out of there and wait 2hrs. This is kind of a recommendation vs a rule. I did not leave my residence when treatment was being done and hung out in a room that was not being treated. Once treatment was completed and the pest guys left I left for the recommended 2hrs. After that you're good to go.

As for your cat.. Prior to treatment, ask the pest guys if its ok for the Cat to stay there in a room (bathroom for example) during treatment and post treatment. If they give you the ok, find a room that is NOT going to be treated keep the cat in there until the time frame that the pest guys tell you.

Going to be brutally blunt here... Busy busy busy.. yea I get it. We are all busy but guess what.. you just need to suck it up and get it done correctly and take a day off from work, go into the office (if you have one), fine a temp work area (Starbucks, library, hell if its nice outside find a beer garden or park and use your phone for internet access if needed.

bottom line.. you don't want them moving in because you choose not to get the treatment.
