How the index works

The Pest Pressure Index converts daily temperature into pest demand: nothing below a 48°F daily mean, rising to full demand at 86°F, easing in extreme heat, with a winter floor of 30. Weekly readings average the daily values. In Columbus the model tracks five years of "pest control" search interest at r=0.80; across 62 metros it runs r=0.93. It measures the market, not any one company.
