      Anti-hobo spikes are usually larger, made using concrete, and found on public benches, shop entrances, and other areas where the homeless might want to rest. Anti-bird spikes are usually made from plastic and mostly placed on fences, balconies, terraces, window sill, and rooftops.

      Imho, both are shitty and display a severe lack of compassion.
