Yes. Your pets and family members that spend time in the yard engaging in outdoor activities are at the greatest risk. Dog poop is the most common carrier of roundworms, hookworms, and whipworms – known gastrointestinal parasites that shed eggs in dog feces. Activities such as gardening, walking barefoot in the yard, or playing sports increase the risk of encountering those parasitic eggs and subsequent larvae. These parasites can also be tracked into the house by pets and shoes affecting occupants of the home.
