My brother two months ago found a few German roaches in his truck and was using traps and pesticides but doesn’t seem to be having any luck. And yes he already cleaned and vacuumed his truck before he placed the traps.

I was thinking of buying pounds dry ice/fozen co2 and placing it in a bucket and just leaving it in his car to sublimate with the windows rolled up. I read that cockroaches cant survive long than 40 minutes without oxygen. Its probably gonna take longer than that to kill the roaches since the car isn’t a vacuum but an entire day should do it.

And since it’s not making direct contact with anything in his car it shouldn’t damage anything? But I actually don’t know. I wanted to know if just having a bunch of co2 in your car would damage anything in it? The materials in the car? Would it cause peeling? I don’t know and wanted to know if it was a dumb idea.
