set up a leaner....
it's a metal trash can or some five gallon buckets
tilted towards their hiding spot but at the precise angle
that when filled with water it's balanced with a propped up
stick ....tie this stick off to some line...
give them a good soaking using this quick splash
and they'll NEVER come back
i had one here doing just that... but it was a feral cat
legally i could have shot it...
but let the dingo tree it and i gave it a good long soaking
with the garden hose.... and never saw it again
