Where Are All Those Mosquitoes Coming From? Check Your Gutters.
You’ve cleared standing water off the patio furniture, drained the kiddie pool, and made sure nothing is collecting water in the yard. The mosquitoes are still everywhere. There’s a good chance the source is sitting above your head the whole time, in gutters that never fully drain.
Why Do Clogged Gutters Attract Mosquitoes?
Leaves, twigs, and debris in a gutter block the downspout and trap water that would otherwise drain away. Standing water is exactly what mosquitoes look for to lay eggs, and a clogged gutter can hold water for days or weeks at a time without anyone noticing.
How Fast Can Mosquitoes Actually Breed in a Gutter?
In warm Utah County summers, mosquitoes can go from egg to biting adult in as little as seven to ten days when standing water sits undisturbed. A gutter that’s been clogged for a couple of weeks is more than enough time for a new batch to hatch right at your roofline.
Is It Just Mosquitoes, or Other Pests Too?
Mosquitoes are the most common issue, but clogged gutters full of decaying leaves also attract wasps building nests and birds or rodents looking for nesting material. A gutter that hasn’t been cleaned in a season can end up hosting more than just standing water.
How Do You Stop It?
Clearing the gutters out and making sure water actually flows through the downspout removes the breeding ground entirely. There’s no spray or treatment needed. Once the standing water is gone, the mosquitoes that were breeding there go with it.
