While there are many different products, there are just a handful of pigeon control strategies. The tool(s) selected is most often a function of site characteristics and management objectives.
In most cases, the strategies can be combined for the best possible outcome and solution for a given site. For example, exclusion can be combined with abatement when both strategies are required to resolve the pigeon infestation.
Since they breed so rapidly, increasing mortality alone does not have a lasting effect or provide a long-term solution for the site.
OvoControl fits in the abatement category by reducing reproduction. This strategy prevents birds from simply refilling the vacuum created from increasing mortality. The population declines naturally, though attrition, with a small remaining flock to keep others from moving in.
