Prevent birds from nesting and destructing your property with Stainless Steel Spikes. This is a non-harmful, easy applicable and highly effective method of bird repellent that is 100% effective where it is installed.
Irritating spikes are low-profile and light-weight. Bird spikes are made from durable and light heavy duty stainless steel. The flexibility of spikes allow mounting on most surfaces and are easy to install. Stackable 1 feet-sized sections make it easy to carry a quantity of spikes, and help minimize waste. Each set of spikes covers one foot, and a spread or width of 8cm. Total coverage per pack is 8feet(2.4m). Set up is easy with a tube of silicone glue included in each box.

Pests:
Birds (pigeons, sparrows, starlings, crows, blackbirds, grackles, seagulls, swallows and more), bats, climbing animals and more.

Uses:
Ledges, beams, rafters, railings, air conditioners, signs, windowsills, gutters, roof perimeters, chimneys, support structures, awnings, poles, lights, statues, trusses, building projections and anywhere else birds roost.

How it Works
Locate the area where birds are roosting or landing. Use screws, nails, glue or zip ties to attach the spikes to the area. The polycarbonate base is the most flexible solution to allow you to place the spikes on flat or rounded surfaces and to adhere well with silicone glue.
The spikes will not harm the bird as it tries to land. The spikes will act as a deterrent and the birds will fly away to find another perch or roosting place.
