I am sorry you have this trouble. However, it is very easy to fox.First do not spray water because then they know you did it.An outside source is necessary.
All you need is a scat mat or air blaster as a permanent deterrent.One emits a harmless static shock, the other a quick burst of air. A few times and they WILL stay off the counter.
I promise it will deter Sherlock and Watson and you will be able to enjoy your meals in peace.
Please let me know how he is doing .
