Cathy's Inescapable Chamber of Death

The cabbages in my previous post were a rare example of the successful combination of childcare and gardening. The dreaded cabbage white moth got the better of my regular inspections last week. One of the girls spotted caterpillars and, armed with a jam-jar each, they happily spent half an hour collecting them up. They think they were making a home for the little critters and carefully filled the jars with grass and leaves to eat. I haven't told them yet, but as soon as they went to bed the caterpillars were dispatched to my slug and snail solution (or "Cathy's Inescapable Chamber of Death" as it is labelled. Doesn't my husband have a nice turn of phrase?). Said chamber is a large plastic box filled with a strong solution of salt water. Salty enough to finish unwanted visitors off quickly, and without any inherent threat to other wildlife - unlike slug pellets which I will never, ever use. All topped off with a nice, tight-fitting lid to thwart any potential escapees. Sorted.
