Pine needles can be a nuisance when they’re left on rocks. Not only do they collect dirt and dust, but they can also create a breeding ground for mosquitoes. To clean up the needles, you’ll need to:
- Remove as much of the dirt and dust as possible. This can be done with a brush, a vacuum cleaner, or your hands.
- Use a plunger to suction onto the needles and pull until all of the dirt and dust has been removed.
- Rinse off the area with water or soap and dry it off.
