While they may look harmless from a distance, groundhogs (often called brown hogs) are prolific diggers that can cause catastrophic damage to your property. Their extensive tunnel systems often wind beneath home foundations, decks, and sheds, leading to structural instability and cracked concrete. Additionally, their appetite for gardens and expensive landscaping can ruin a backyard overnight. Because groundhogs can be aggressive when cornered and are known carriers of parasites, professional trapping and relocation are the only safe ways to handle an infestation in Jacksonville.
