Is this the first time in 10 years that you've had a problematic frog population? Some years it just seems like there are more than others. I don't find the frogs to be particularly loud - but the toads are when they spawn. Are you sure you don't have toads? And if that is the case, they will leave as soon as they are done spawning, so just be patient for a little while.
If they are permanent, resident frogs? I say embrace the noisy, messy mayhem. But then again, I love the wild critters just about as much as my fish.
