Which Pests Come Out in the Winter
Of course, one very appealing place for insects to hide for the winter is in the warmth of your home. There, they can find food, water, and shelter, and even safety from predators.
You probably don’t have to worry about the species of ants that nest underground or in trees. However, if you’ve got carpenter ants or another species that likes to nest in the structure of your home, you could find yourself with a substantial ant problem.
Unfortunately, since bed bugs feed on human blood, they live indoors year-round. If you see signs of a bed bug infestation, no matter what time of year it is, call a pest control professional immediately.
Famously, cockroaches can thrive in a wide variety of climates, including extremely cold temperatures. Although cockroaches can survive the winter outdoors, the species that act as pests prefer to be near sources of warmth and food, including your home.
These creatures, also called lady beetles, go into diapause during the winter, and they often huddle together for warmth on trees or the sides of houses. Interestingly, they will nearly always group up on the south sides of these surfaces for maximum warmth, though they may also sneak inside your home if given the chance.
Although silverfish prefer warm, damp habitats, they can survive in temperatures as low as freezing and as high as 100°F. While they can go dormant in the winter, silverfish in your home have no need to do so and will stay active all winter long.
Different species of spiders have different ways of dealing with the cold. Many can simply tough it out. Others lay eggs before they die off. However, most don’t actually seek out the warm temperatures of your home; those that come inside usually do so by accident.
Stink bugs, however, are notorious for seeking shelter in residential buildings for the winter, sometimes in large numbers. Once indoors, they may go into diapause, but some stray stink bugs may remain somewhat active all winter.
Termites remain active year round—even on winter days. Cold outdoor temperatures have little effect on drywood and subterranean termites that have found food and shelter in your home’s walls and foundation. And while you may not see swarms from December through February unless you live in a warmer climate, like tropical Florida, you may see other signs of termites in the winter, such as mud tubes or damaged wood.
