According to PestWorld.org, ants are very successful at overwintering in the great outdoors, including our own yards. During the fall months, ants indulge in vast amounts of food with the goal of putting on fat to survive for weeks on end without eating. As the winter chill arrives, their body temperature – and productivity – significantly decreases, so they seal up their colony and hunker down in deep soil or under rocks until Spring has sprung.
Bed bugs can NOT withstand high heat temperatures (and this is why we use electric heat treatments to eliminate bed bugs) - all stages die instantly at 122 degrees. They can, however, survive nearly freezing. They do often succumb after a few days of exposure to temperatures below 32 degrees Fahrenheit. The bad news is our homes or public transportation provide the perfect habitat for bed bugs to survive during the winter months.
Cockroaches have been around for 250 million years and have survived many extinction events, including the end of the dinosaurs. We've all heard (true) horror stories about how their headless bodies can live on for several weeks, and their disembodied head for several hours. Most of the 50-plus United States cockroach species can survive year-round, as long as they have easy access to a warm, moist environment.
These biting insects won't be eliminated during the winter months, but instead, are currently hibernating in protected places like hollow logs. As the Winter weather leaves and Spring arrives, female mosquitoes awaken and seek out a blood source to feed and begin developing eggs. The rainy Spring adds to the Summer mosquito populations as mosquitos breed in standing water.
In colder climates, subterranean termites will dig deeper into the soil – below the frost line – to stay warm. In the spring, when the temperature reaches about 70 degrees, we start getting calls off the wall about young male and female termite swarmers emerging from their nests to find a mate and new nest location (often inside our homes.)
