Your gutter system is an ideal environment for mosquitoes (and other disease carrying insects) to breed. In order to reproduce, mosquitoes require approximately 1 inch of standing water. Since this is common in clogged gutters, mosquitoes develop and become adults in approximately one week!!!!  Imagine, a mosquito breeding ground practically right in your own home! Did you know, mosquitoes are territorial and will actually defend their environment? Did you also know that small children are often allergic to mosquito bites and that mosquitoes carry the West Nile Virus? The GutterStuff Pro system reduces the potential for disease carrying insects. First, GutterStuff Pro keeps out debris so gutters remain clear and can drain properly. This alone eliminates most standing water.  Secondly, GutterStuff Pro completely blocks insect access to the gutters by entirely covering the gutter. GutterStuff Pro allows water to flow across the entire surface of your gutters while preventing insect breeding by fully covering the gutter.  As a result, insects are forced to relocate. Help protect yourself and your family against insects and the potential of disease.  GutterStuff Pro...It simply works.
