The answer to 'stone walkway pests' is that the most common pests that can infest stone walkways are weeds, ants, and moss. Weeds can grow in the cracks and crevices of the stones, disrupting the walkway's appearance and structure. Ants may build their nests under the stones, causing uneven settling and potential tripping hazards. Moss can grow on the damp, shaded areas of the walkway, making the surface slippery and unsafe.
To address these issues, you can start by regularly inspecting the walkway and removing any weeds, ants, or moss that you find. For weeds, you can pull them by hand or use a weed killer designed for use on stone surfaces. For ant infestations, you may need to use an ant bait or contact a professional pest control service. Moss can be removed by scrubbing the affected areas with a stiff brush and a solution of water and bleach or vinegar. If the problem persists or the walkway is severely damaged, it's best to consult a professional landscaper who can assess the situation and provide the appropriate solution, which may include repairing or replacing the walkway.
