Mosquito breeding in eaves trough extensions.
I have several 10 to 15 foot extensions for my downspouts, made of corrugated black plastic about 4" in diameter. I suspect the corrugations allow pools of water in which mosquitos can breed. Is this true? If so, how can I prevent the mosquitos from breeding? I have never seen any non-corrugated eaves trough extensions, but perhaps they exist. Do you know of any non-corrugated extensions I could buy? Is there any kind of chemical or other product that I could pour in to these extensions to prevent the mosquitos from breeding in them? Would it have to be replaced after every rain? Thanks in advance

Are the gutter extensions perforated all along their length?
If not, you can secure a fine mesh like pantyhose to the end of the extension to keep mosquitoes out.
