Keep your colonies protected and accessible all winter long. This durable side wrap makes it easy to check hives and feed bees during overwintering. Build in your own upper entrances to allow bees to take cleansing flights on warm winter days while also providing ventilation to prevent overheating. Made from tough, long-lasting reinforced poly fabric, it features a 9" flap and bonded polyester insulation—no fiberglass, so no rash or health hazards. When paired with the Winter Top and Pillow (each sold separately), it offers complete winter coverage. Field tests show that mice and other pests are rarely a problem, giving your bees a safe, comfortable environment until spring.
