Oh Bunter, sorry about your super electrical loving ants! I think some sort of sticky stuff around might dissuade them. Now I am concerned about what you said before about not putting pool tablets in the skimmer baskets because the people that look after our pool have always put them there & still do!  Last year our pool pipes had to be renewed!  No one said that the cause was where the tablet were placed.  So please tell me  where to put the  tablets .  :-/?
