My house is right next to a creek, with a waterfall. I love listening to the falls at night. BUT this spring it is infested with frogs. Thought that was cool the first few nights, but all night long CRRREEEEK, RRRRIIIIBBBBIIITTT!!! So this afternoon I got 10 galon jugs of clorox and sprayed the whole area with my hudson sprayer! tonight, silence. BTW, I don't think they all died, they just moved on.
