Closing the pool today and found a nest of the tiny buggers (less than an eighth inch long) had taken up residence in the folds of my pool cover. Pulled it out, sprayed it off and now they're high-tailing it. So I'm wondering if that might have compromised the tarp cover and if there might be any issue with using it other than getting their detritus in what otherwise is a very clean pool ready to close. Anybody else had to deal with something like this?
