Look at places that have moisture or cellulose material. Is there any wet wood, whether it be a part of your house or a wood pile next to your property? These are the most likely places you'll find termites, so examine these areas of your property carefully. Do you have any sort of organic material made of wood around you house? Make sure you're disposing of it. The longer it's allowed to stay out and gain moisture, the more likely it will attract termites to your location.
