Two replacement bait tubes for the Skeeter Hawk Backyard Mosquito Bait Station. Each tube holds the station's natural mosquito bait: mosquitoes attracted by the station's UV light feed on it and die before they can breed, which reduces the population around the house over time. Replace the tube when it runs out or reaches the end of its stated life to keep the station working. Fit the tube according to the instructions on the pack and keep spare tubes sealed until use. These tubes suit the Skeeter Hawk bait station only. Dispose of used tubes as described on the pack.
