Everyone knows that many types of insects thrive in stagnant water. In fact, according to experts, mosquito eggs are able to hatch in as little as one tablespoon of water. Think about it: If mosquitoes can multiply anywhere even a tiny amount of water collects, imagine how much insect activity can take place in a clogged gutter. True, most of the time insects are merely annoying. But the damp, decaying environment created by a stopped-up storm drainage system also lures carpenter ants, termites, and other wood-destroying pests. In other words, there's a lot more than personal discomfort on the line. The same conditions that breed mosquitoes can breed significant property damage.
