Why Clogged Gutters Attract Mosquitoes & Other Bugs


Pests come in all shapes, sizes and colors. Some pests even resemble each other just enough to be hard to accurately identify. However, regardless of looks and identity, all pests have one thing in common—they all need moisture for survival. Controlling excess moisture in and around the home is the first step in effective pest control.

There are many places around a home that collects standing water. This can include low spots in the ground, birdbaths, flower pots and wading pools. However, one overlooked water problem is in the area of clogged gutters. Leaves and twigs fall from trees onto the roof and get washed down into the gutter and downspouts. This debris accumulates, collects moisture and begins to decay and rot. The guttering and downspouts clog up causing standing water to accumulate in the guttering. This becomes an ideal habitation and breeding grounds for mosquitoes, ants and other pests.

Mosquitoes need standing water in which to lay their eggs. In fact, the hatched nymphs must have standing water to live in and survive as they mature into adult mosquitoes. These clogged gutters become a favorite habitat and breeding ground for those stinging, irritating mosquitoes. It is believed that mosquitoes stay in close proximity of their breeding grounds, usually not straying more than 200 feet from where they were hatched.

A mosquito only needs a very small amount of standing water to breed and lay their eggs. The first three stages of mosquito growth—egg, larvae and pupa—require standing water for their development. The standing water in your guttering is more than enough for breeding, hatching and growth. The rotting, decaying leaves provide the nourishment and water needed for their development. This will unquestionably cause an increase in the mosquito population on your property.

In addition to mosquitoes, your clogged gutters act as a safe haven for other bugs and insects including gnats, cockroaches, flies, ants and termites. Worms, spiders and snakes also find clogged gutters to be an ideal environment for breeding and feeding grounds.

Ants often find your clogged gutters with all those leaves, decaying twigs and dirt to be an ideal choice for their cozy home. Most ants like to live outdoors and forage for food inside the home. Clogged gutters allow convenient access for both.

Termites love moisture and rotting wood. A clogged gutter with standing water provides an ideal environment for them. The standing water overflows and drains down the side of the building, often creating damp wood for them to eat.

Keeping guttering clean and flowing freely should be at the top of the list of your preventive tips for controlling these household pests.  To find out how Schendel Pest Services can help you keep your gutters free of debris with our Leaf Defender, visit our home pest control page and be sure to scroll down to the bottom of the page.  Or simply complete our online form and we’ll contact you.
