West Nile virus is the most common mosquito-borne disease in Kansas and the United States.
The risk of acquiring a West Nile infection depends on various factors including time of year, number and location of infected species of mosquitoes, and the number of days with sufficient heat, according to the KDHE web site.
Warm temperatures increase the rate of mosquito larvae development which increases the mosquito population size. The risk of WNV transmission usually reaches peak transmission during July, August, and September.
The KDHE says to avoid mosquito bites, follow the three Ds
- DRAIN – eliminate standing water where mosquitoes live and breed
- Empty standing water from tarps, old tires, buckets, and other places where rainwater collects. Use larvicide in low-lying areas where water cannot be removed.
- Refresh water for bird baths, pet bowls, and wading pools at least every three days.
- DRESS – cover your skin with clothing when outdoors
- Wear protective clothing when practical (long sleeves and pants).
- Limit outdoor activities when mosquitoes are most active.
- DEET – use insect repellents that contact DEET or other EPA-approved repellents
- When used as directed, EPA-registered insect repellents are proven safe and effective, even for pregnant and breastfeeding women.
