Fight Back Against Mosquitoes

Nobody likes mosquitoes. They are bloodsucking, disease-spreading pests. Not only are mosquito bites itchy and painful, but mosquitoes spread some of the world’s deadliest and most debilitating diseases including West Nile virus, malaria, chikungunya and dengue fever.

Mosquitoes are such a serious health threat and their control so vital that they have an official week devoted to their extermination.

Late June is National Mosquito Control Awareness Week by the American Mosquito Control Association (AMCA). The goal of Mosquito Control Awareness Week is to educate the public about the dangers of mosquitoes and the importance of mosquito control in the prevention of disease.

According to mosquito expert Joe Conlon, Technical Advisor for the AMCA, it is impossible to live in a completely mosquito-free environment. Wherever there’s moisture there will be mosquitoes—even in times of drought. But you can reduce your chances of getting bitten by mosquito pests by being “mosquito smart” and reducing places where mosquitoes can breed.

Why Do Mosquitoes Bite?
A female mosquito will bite humans, mammals and birds in search of a blood meal so she can produce eggs. She can extract up to four times her weight in blood. Immediately after biting a person or an animal, a female mosquito lays her eggs in standing water—usually only yards from where the bite occurred.

To reduce the chances of getting mosquito bites, limit your outdoor activities during the times of day when mosquitoes are most active—an hour before and after dawn and an hour before and after dusk. Keep as much of your skin covered as possible by wearing long sleeves and long pants. But wear light-colored clothing, because mosquitoes are attracted to darker colors.

Using mosquito repellent is another good way to keep mosquitoes—and mosquito bites—at bay. Apply repellent directly to skin or clothing as recommended on the product label. Summit® Mosquito Repellent Coils can also be used on patios and in backyards to keep mosquitoes away.

Reduce Mosquito Breeding Sites
It doesn’t take much standing water to become a mosquito breeding site. “Some species of mosquitoes can breed in as little as a bottlecap full of water,” said Jonathan Cohen, mosquito control expert and President of Summit Responsible Solutions. “That’s why homeowners need to be vigilant in eliminating places where water can collect and stand in their yards and gardens.”

To reduce mosquito breeding grounds, dispose of cans, plastic containers, old tires and other items that can collect water. Turn over wheelbarrows and empty children’s wading pools. Clean clogged roof gutters, which can become prime mosquito-breeding pools. Periodically empty the saucers under ceramic pots to make sure they are not harboring mosquito larvae.

To prevent mosquitoes from breeding in places where water collects—including ponds, bird baths, animal watering troughs, gutters, tree holes and rain barrels—use a mosquito control product that contains BTI to kill mosquito larvae. BTI (Bacillus thuringiensis israelensis) is a bacterium that naturally kills mosquito larvae before they can grow up to become flying, biting, disease-spreading adults. Even though BTI is deadly to mosquito larvae, it is harmless to people, pets, fish, wildlife and beneficial insects. BTI is the active ingredient in Mosquito Dunks, the number-one selling biological mosquito control product. When a donut-shaped Mosquito Dunk is placed in standing water, the BTI in the Dunk will kill mosquito larvae for up to 30 days.

In places where small amounts of water collect—such as tree holes, potted plant saucers and water reservoirs in self-watering planters, a BTI product called Mosquito Bits is a good way to kill mosquito larvae. Mosquito Bits granules can be sprinkled into virtually any place where water can collect. Mosquito Bits can also be used to kill mosquito larvae in swampy areas and other areas where water cannot be drained. In addition, Mosquito Bits are highly effective as a “shock treatment” in water where immediate larval control is needed due to an extremely dense population of mosquito larvae, because the Bits release all of their active ingredient, BTI, at once. The Mosquito Bits application can be immediately followed by the addition of the Mosquito Dunks® for long-term control.

To kill adult mosquitoes, use a permethrin-based insecticide such as Summit Mosquito and Gnat Barrier. The permethrin in Summit Mosquito and Gnat Barrier kills and repels mosquitoes and other insect pests for up to four weeks. Simply attach a garden hose to the hose-end sprayer bottle and spray the yard perimeter and fences, plus the lawn and vegetation where mosquitoes can hide and rest.

By reducing exposure to mosquitoes, limiting breeding sites and using the most effective types of mosquito control products, you can greatly reduce your chances of being bitten by disease-carrying mosquitoes.

Mosquito Dunks, Mosquito Bits, Summit Mosquito and Gnat Barrier, and Summit Mosquito Repellent Coils are available at the garden centers, hardware stores, home centers and online retailers. For more information visit
