The Tega Cay Wildlife Conservation Society in South Carolina has received approval from the state’s Department of Pesticide Regulation to use ZonaStat-D, also known as PZP, to control the city’s growing deer population.

PZP is a natural protein that prevents pregnancy in deer by boosting their immune system.

The method involves darting the protein into female deer in the Tega Cay area.

The city council will need to officially approve the use of PZP over the sharp shooting method known as culling, and the cost of the program is still being evaluated.

According to CN2 News, City leaders say the herd continues to grow, estimating more than 1,000 deer in the city.
