A rarely acknowledged benefit of winter is the reprieve from flies it brings. Many fly species spend the winter months as pupa – the stage during which larvae or maggots transform into adult flies. Then in late winter or early spring, they emerge in winged form to buzz around picnics, dumpsters, homes and businesses.
There are many different types of flies, including house flies, little house flies, bottle flies, cluster flies, fruit flies and more. Although many people see them as merely annoying, flies pose a perennial commercial and residential pest control problem. Because these pests are so ubiquitous – and because prevention is usually more effective than cure – pest control for flies is a year-round activity.
Fall is the best time to prevent flies from taking up residence around your home or business. This is when the pests will typically enter a building, looking for a place to lay eggs. Some, such as cluster and face flies, will even spend the winter indoors as adults until a stretch of clear, bright weather rouses them. Once flies have chosen your building as their winter resort, there’s little you can do to prevent them from emerging in the spring. However, it helps to keep in mind that the appearance of adult flies in early spring doesn’t necessarily mean you have a current problem; it could merely be a residual effect from a problem that occurred last fall. We often see this with bottle flies, which typically lay eggs on dead animals.
