Bradfordlass72 Your 'ant' story reminded me of last time I was visiting my daughter in Australia. They have an automatic garden-watering system. She lifted the lid, to adjust the timer, and found the box seething with ants. She was about to go for the killer spray, but I told her that, if she left the lid open, the ants would remove themselves. Sure enough, a procession of ants, carrying their eggs, began to evacuate the box. Within an hour they were all gone.
I congratulated myself on saving all those little lives.
Unfortunately, finding that the box was closed and dark again, they all moved back in! My heartless daughter squirted the lot!
