Flea life cycle never ends with the possibility to run indoors. The outdoor activity allows an exponential increase in flea population during the warm season.

N.B. Average temperature of the daylight (night not included): 12h, 18h, 24h

Wind: 0 above 5 (Beaufort scale) I.e   The model indicates the potential that fleas have for multiplying and living in outdoor environments. It definitively does not refer to indoor environments (houses, flats etc). As a result, the absence of activity in winter refers only to gardens, undergrowth, unheated barns etc, since the lifecycle of fleas does not end in heated environments (even if it is set at a temperature of 19°C~22°C).

Once all the data, adjustments and biological matrices have been compiled, two indices are obtained.

  • Activity index
  • Density index
