Exploratory Tunnelling

Exploratory Tunnelling activity is dependant on two key factors:

  1. Sand particle size
  2. Moisture in soil

The rate of progress of a termite foraging through the soil is related to the soil type/size and the moisture content. From studies, the following tables show the effect over the distance covered.

The 250-355 micro range is quality top dressing soil," LIVING SOIL" (not washed sand). This is more important than using non-repellent chemicals and can be a great advantage with in-ground baiting systems.
