PondXpert Floating Pond Protector Rings
Herons are bad for garden ponds because they can eat the fish and other animals in the pond. They can also damage the plants and the pond liner with their sharp beaks. Herons are mostly solitary and shy birds, so they can be deterred by various methods, such as netting, decoys or fencing.
PondXpert's PXPPROT floating pond fish protection system is made up of interlocking floating grid rings that form a barrier to herons and cats entering your pond, a great effective alternative to pond nets or garden webbing.
