The answer to 'stone walkway pests' is that common pests that can infest stone walkways include ants, weeds, and moss. Ants can build nests in the crevices between stones, weeds can grow up through the joints, and moss can grow on the surface, making the walkway slippery. These pests can damage the walkway and create an unsightly appearance.
To address these issues, you can try DIY solutions like using ant bait, applying herbicide to weeds, and using a moss remover. However, for more severe infestations or if the problem persists, it's best to call a professional landscaping or pest control service to properly identify and treat the issue.
