They make it too uncomfortable, if not impossible, for birds to alight. Spikes come in one-foot strips that can be glued to most flat surfaces on buildings, warehouses, loading docks, overhangs, ledges, fences, and similar perches preferred by pigeons. It was a complex situation, Mercado explains, so he suggested a combination of approaches. First, he recommended that his customer use Spikes on the building's garage and on the fence that bordered the office property. Then they installed coiled wire under the beams inside the garage and a tacky substance on the balconies and patios.
Spikes work to discourage pigeons from landing.
Trial Run is Visible Proof. In 15 years of owning and operating his maintenance supply business, Oswaldo Mercado has learned much about customers. He suggests that they use Spikes in a small section for a few weeks. For most customers, Spikes do the job. The trial period leads to full-fledged use and satisfied customers, he believes.
