Every time it rains, I find worms in my pool. Yesterday I vacuumed and drained a bit in anticipation of the rain. The pool was spotless. We got maybe 1/4" of rain overnight. The top of the fence is wet, but the verticle faces are dry. Patio's wet, totally dry beneath the eaves. Meaning: it didn't rain very hard. So why are there huge earthworms in my pool? They didn't get washed there by torrential rains. They would have had to climb out of a planter and cross a couple feet of concrete or come out of the lawn and cross even more concrete to end up in the pool. Then what? Do they commit suicide by drowning? I don't see any on the patio, they're all in the pool.
Anybody got a reason or a theory?
