Ant Guard Large Clear
Our Super Big Clear Nectar Ant Guard holds three times more water than standard protectors or built-in ant moat traps - that means less maintenance. This high quality plastic nectar protector fits between your hummingbird feeder and your hanger. Strong construction holds even the biggest hummingbird feeders. Plus, it's clear so you can monitor water levels. Use water or petroleum jelly. 4 x 4 inches.
