DeSoto County has gone high-tech to keep mosquitoes and West Nile Virus at bay. We followed a mosquito control officer to see how. Garfield Carter has a biting problem. The DeSoto County resident said, "We have this big major problem with mosquitos where they are just horrendous because we have water drain right there behind you, and it doesn't drain the water properly." County officials say they've gone high-tech in the battle against mosquitos and West Nile Virus. Robert Nelson, mosquito control officer said, "Yesterday, I treated that area with lacerative because there was a standing water pool, that it looked like it might have had mosquito larva in it. Hung traps to get a count and we did find a significant number of mosquitos." The larvacides Nelson is talking about kills mosquito larvae before they can become flying and biting adults, and is being used in areas of high concentration. But first, the areas have to be identified. All it took for Carter was a phone call to the county. Then, mosquito control officers come and set up dry ice traps. Dry ice emits carbon dioxide, like humans, which attracts the mosquitos. Nelson traps about 25 mosquitos, which is considered a large number. "We are going to make sure that area is sprayed with adulticide." For Carter, the treatment is a relief and money well spent.
