Can bed bugs survive the winter in a summer house?

Yes, if the summer house is kept above freezing. Bed bugs can survive up to 300 days without a blood meal, depending on temperature.

They die at 0°F (-18°C) if exposed for at least 4 days. Some studies suggest that slightly higher subzero temperatures, like 23°F (-5°C), can work if maintained for about 2 weeks, though eggs are more resistant and may survive shorter exposures.

They will become active again when the weather warms up and a blood meal becomes available.
