Insects are less active in the winter, except on warm days; however many pests can still be active in and around your home. Many will move into or under your home to keep warm during the cooler months. Rodents are especially problematic due to colder temperatures outside and warm, cozy homes inside. Yellow jackets (paper wasp) are very common in the fall and winter months. Cockroaches are always a challenge because of our climate-controlled homes as well as structure-infesting ants.
