A clogged gutter is a mosquito nursery right above your head

When gutters clog, water stops flowing and starts pooling. Add a layer of decomposing leaves, shingle grit, and pollen, and you've created still, warm, nutrient-rich water — exactly the conditions mosquitoes need to lay eggs and develop larvae. The organic debris doesn't just block drainage; it feeds the next generation.

In Florida, where mosquito season stretches through most of the year and rain fills gutters frequently, a neglected gutter can cycle through multiple mosquito generations before you notice the problem. The adults then disperse right at roofline level — directly above your front door and patio.
