Termite detection

A house on the Spanish campo needs protection against termites, as they are abundant here. 12 detectors were bought. Those are plastic containers with a piece of wood, and a baiting substance. The containers are placed in the ground around your house. Where there are termites they will find the detector, eat the wood and bait, so you know: ah, termites. You then replace the bait with poison, and get rid of them. Termites are very useful, but not in your house.

In the upper part the container with bait, at the bottom wood. Needs checking every 3 months..
