Here in NE Florida, we had our first significant rain in about the last 35 days or so, on a Friday night. Went out to the pool Saturday morning, and found about 150 earthworms on the bottom of the pool. Seems to happen every time it rains, after a dry spell. This time was the worse.

IG fiberglass with about a minimum of 4 feet of decking all the way around.

Any ideas on how to stop them?

Thanks, jeff
