It's summer. It's stinking hot. And for any silly person who leaves their pets (or any imbecile who leaves their kids) inside a parked car, watch this video where a doctor traps himself inside a parked car to see how how it gets. Even with all four windows cracked down a bit, the car temperature reaches 117 degrees in only 30 minutes. And no. Even if you leave your pet inside for just five minutes, the temperature already spikes and becomes miserable.
This is a Yes and No answer. It all depends on where you live. In most places during the summer if you leave your car outside in the sun for hours and the entire inside of the car reaches temperatures of over 120 F for any length of time it will kill the bedbugs and their eggs.
