Worms work best in dark, moist conditions. Our breathable Moisture Mats provide these conditions where they are most needed, on the surface of your composter. They encourage the worms to work in the freshest waste, thereby speeding up composting and reducing odours.

Simply pop the mat on the very top of your wormery (just below the lid) and then lift to add waste underneath. Each mat will last 2 Months + and then just pop a replacement on the top.
