Gardman Flip Top Mealworm & Suet Treats Feeder is a refillable wild-bird feeder intended for compatible mealworms and suet treats. The flip-top design provides access for refilling. Hang the feeder securely in a suitable location and clean it regularly, removing stale or spoiled food to support good feeder hygiene.
