Termites are consistently travelling through the soil looking for food and moisture. The idea behind an interception and baiting system is to pick up foraging termite traveling under ground.
This bait station has done just that, picked up active schedorhinotermes allowing us to now apply the bait, if you look closely this stations has already been baited 4 weeks ago, this demonstrates effectiveness of this system to pick up live termites, bait them and allow them time to consume the bait within the station, like they have in this video.
