Upward-pointing spikes are the simplest and least expensive way of deterring birds from alighting on specific areas like ledges, parapets, beams, pipes, gutters and roof ridges. They are especially suitable for proofing against pigeons, gulls and starlings, although can have limited success in some high pressure nesting and night roosting applications. Spikes can be fixed to almost any surface quickly and easily with adhesive, tend to be difficult to see from a distance, and can last as long as nets. The angle at which wires are mounted in the bases, the tensile strength of the wires, the distance between them, the stability of their base-plates and the correct length of wires for the species are all important criteria when selecting bird spikes.
