I'll make it quick: Did the bed bugs die in my hot car?


I’ll make it quick.

-Slept in a room with a blanket and soon bites showed up.

-Before I noticed the bites, the blanket I was using was put into the back of my car. I absolutely forgot about it. This was back in May. I’m an idiot, I know.

-It has been a VERY hot summer, and the temperature has absolutely gotten above 120 degrees inside my car for hours and hours on hot days sitting in the sun.

If this blanket did happen to have bed bugs, do you think they definitely would have died by now?

Thank SO much for your time!


We’re based in South Florida, so I can also attest that it’s easy for a car to hit 120 degrees in a hot parking lot. Not pleasant for a mid-day lunch run.

It’s theoretically possible for a sun-cooked car to be lethal to bed bugs, but I wouldn’t bet on it. A car is full of nooks and crannies with varying levels of insulation. While some parts of the car (especially the parts most exposed to the sun) might hit 120+ for some time, other parts won’t. Bed bugs are very sensitive to heat (more than we are), so they’re likely to find and hide in those cooler spots and wait out the day.
