Advertisement The La Crosse County Health Department mosquito control officer said prevention, education and a multi-county mosquito control program based in La Crosse County have played a major role in reducing the number of encephalitis cases in the area by 90 percent during the past 30 years.
Geske said his mosquito control budget has been stretched and his efforts challenged this summer by heavy rain and flooding. But until the recent hot, humid weather, disease-carrying mosquitoes weren’t moving much, he said.
“Now there is so much water and there are so many mosquitoes and the weather is just right — hot and humid,” Geske said. “We’re trying to stay on top of it, but it’s a tough battle.”
Geske said now is the time for people to be vigilant about prevention and education. He said he has seen plenty of disease-carrying mosquitoes already and the peak months are August and September.
No encephalitis or West Nile cases have been reported in the area so far this year.
Nationwide, 28 West Nile cases have been recorded so far.
Geske said if everyone followed five steps, there would no encephalitis or West Nile cases. Here’s what you can do:
1 Keep no artificial, man-made habitat — tires, containers, boats, wading pools and bird baths — with standing water in your environment. Dump the water. Keep containers inside. Ensure roof rain gutters drain properly. Water can accumulate on tarps. Make sure there is no standing water in your yard. If you have tree holes, fill them with concrete to prevent water from building up.
2 Use mosquito repellents containing DEET and always follow the label directions. Use especially in late afternoon and early evening when mosquitoes are active.
3 Do not use colognes or after-shave lotions, which can attract mosquitoes. If walking through a woodland area, wear long-sleeved shirts and pants.
4 Mosquito-proof your home. Fix window screens in disrepair. Mosquitoes are attracted to lights and heat in the home.
5 Report clogged storm sewers and ditches holding water. Quiet, long-term ponded areas with 11/2 inches or less of water are perfect breeding places for mosquitoes that carry encephalitis and West Nile. Report these areas to the La Crosse County Health Department at (608) 785-9872.
