Kitty litter around the ground rods will do wonders.
The cheaper the better, try to find the main ingredient,
bentonite clay. It adsorbs moisture at a very good rate
effetely increasing your ground conductivity around the
ground rod.
Of course you will have to dig out the hole around
the ground rods.
Had the same problem here, lighting kept taking out
my well pump. I reground the utility pole on my own.
Added another rod, added three rods at the utility panel
for the house. No hits in 5 years, now that I said that POOF !
