Extension advice: Control biting bug with these tips

Richard Evans is UGA Extension Service agent in Bryan County.

With our large amount of rain from April and May showers, mosquito calls have been coming into the Bryan County Extension office more frequently.

After some time in cool weather, we are now suddenly facing a mosquito “baby boom.” Mosquito eggs lie dormant until they’re immersed in water, which signals them to hatch.

Because South Georgia didn’t have enough rain to flood their habitats last summer, leftover eggs from years gone by were just waiting to be soaked and stimulated to hatch.

The best way to limit the insects’ population explosion is to focus on pools of water left behind by all the rains. These are prime breeding grounds for mosquitoes.

Don’t worry about ditches or streams where the water is moving. Mosquito larvae can’t develop in flowing water.

Controlling breeding sites

The cheapest and best way to control mosquitoes is to get rid of places where they breed. Used tires, for instance, are significant breeding sites.

Tires should be recycled and properly disposed of to keep them from becoming mosquito sources. There are more potential ”mosquito nurseries” than you might think. Here are some tips to help prevent mosquito problems.

• Remove old tires or drill holes in those used for playground equipment to allow them to drain. Tires are common larval habitats for several mosquitoes that bite humans and should not be stored outdoors.

• Check boats for holding water, clear drain holes, turn over, cover or increase angle to aid drainage.

• Remove vegetation or obstructions in drainage ditches that prevent the flow of water.

• Pick up broken, unused or discarded toys that hold water.

• Pick up all beverage containers and cups.

• Replace water in birdbaths and other animal feeding dishes or troughs once a week.

• Fill tree holes (hardwood trees) that hold water with a spray insulating foam sealant.

• Position garbage cans and lids so they don’t hold water.

• Change water in planters, including hanging plants, at least once a

• Fix dripping outdoor faucets that create pools of water.

For personal protection

For the mosquitoes that have already hatched, repellents can help protect you from bites. Here are ways to limit your exposure to mosquitoes:

• Wear light colored clothes outside. Dark colors attract mosquitoes.

• Stay indoors at dawn and dusk, when mosquitoes are usually most active.

• Wear a repellent containing DEET, and treat clothing with a product such as Permanone (containing permethrin). Herbal repellents work for less than an hour. The No Gnats spray I’ve found works and smells great, but needs to be reapplied hourly for good protection.

• If you use citronella candles, orient them so the breeze directs the candle smoke toward you. The smoke is what repels mosquitoes.

Always follow label instructions to protect you and the environment.

But a word or two of caution about what you buy to control mosquitoes – they’re not always what they claim to be.

Mosquito plants don’t repel mosquitoes very well if at all. Neither does garlic, herbal bracelets or ultrasonic devices. Also keep in mind that traps that use light or carbon dioxide to lure in insects may attract more mosquitoes than they kill.
