A: Occasionally, insects or other pests may invade homes. Some may simply be nuisances that do not harm the home, its contents, or the inhabitants. Others may infest food products or damage fabrics. Some can damage the home's structure and others may pose a health risk to people and/or their pets. If this occurs a Pest Control Professional may need to be called in.
