Gridwire / Twine
Gridwire can be suspended in various horizontal and vertical patterns to deter large aquatic birds. You can protect lakes, parking lots, warehouse roofs, etc. from gulls, geese, and other large aquatic birds.
Polythylene Florescent GridTwine is more visible to birds than GridWire. This florescent GridTwine is intertwined with two strands of Stainless Steel wire for added longevity.
