While you can't completely stop termites from entering your house, there're ways to ensure you can prevent the infestation. There're a few things you can do: - Make sure to keep water away from the foundation of the house - Make proper use of mulch - Don't store firewood in small spaces or against foundations, as they're the easiest target for infestation. - Eliminate wood in contact with the ground - Reduce moisture and humidity in small spaces - Get your home professionally treated with a termiticide
