I remember watching a rerun of this back in the 80's. There was this one episode I think it was from this series that had the Robinson Family in a confrontation with some very angry army ants. One of the older siblings gets biten bad by the vicious ants and needs to be treated. The Robinson troupe end up trying to burn all the ants and get some success in killing most of them. I can't remember the episode name but it was a pretty fun Ep. I guess the ants were terminated literally after the shoot.
I apoligize this episode may have been from a different Swiss Family tv series.
