How do bugs survive in autumn?

Don't underestimate the vitality of bedbugs. When the weather is cold, they will find a hidden place to hide, and when the temperature is slightly higher, they will come out to move. But you rarely see it. Besides, bedbugs can live for several months by sucking blood once.

After mating in a hidden place, adults lay eggs in gaps such as walls and bed boards. Usually one to several eggs are laid at a time, and the total number can reach 100-200. In winter, bedbugs usually stop sucking blood and laying eggs. Larvae can live for more than 30 days without sucking blood, and adults can live for six or seven months without sucking blood.

I hope this helps.
