The bad news was that the bugs didnât die nearly as quickly as other studies had found, a mere hour or two at -16Â° or -17Â° Celsius. âIn our study, bedbugs survived lower temperatures, with eggs surviving in short-term exposures â¦ to temperatures as low as -25Â° C,â the researchers write. But the bugs are not freeze tolerant, the scientists found, and they can be killed â no matter their stage of life or feeding status.
