The length of this stage averages 8 to 9 days. Depending upon weather conditions, population explosions typically occur 5 to 6 weeks after the weather starts to warm up. The adults emerge from their cocoons when they detect heat, vibrations and exhaled carbon dioxide indicating that a host is nearby. Once they hop onto a host, the adults mate and begin the life cycle all over again. The entire life cycle can be as short as 3 to 4 weeks.
