Nests in particular have a lot of pheromones that the bird uses to recognize their home. This is what we call imprinting. When you put spikes over their nesting sites, birds will build right over them. As you can see in this photo, it doesnt matter how many spikes were placed. The resident birds were going to reclaim their spot. Remember, dont use spikes to solve nesting birds! PACKAGE INCLUDES:
