South Dakota Health Department Issues Mosquito Warning

When you experience the torrential rains that South Dakota and the rest of the Upper Midwest endured recently there are serious consequences, some immediate and some and delayed.

Widespread flooding and destruction hit almost right away, but now there's another issue coming as a result of all of that water.

The South Dakota Department of Health (DOH) is advising residents to take proactive steps to reduce mosquito populations following recent floods in several southeastern counties.

The DOH says the excess water from flooding creates ideal breeding conditions for mosquitoes, especially the nuisance species Aedes vexans. While Aedes vexans does not typically carry the West Nile Virus (WNV), another species, Culex tarsalis, can pose a significant risk.

Cutting back on mosquito infestations starts with removing standing water from your property.

The DOH has these suggestions:

• Empty and Scrub: Turn over, cover, or throw out any items that hold water, such as tires, buckets, planters, toys, pools, birdbaths, flowerpot saucers, or trash containers. Mosquitoes lay eggs near water.
• Cover Water Storage Containers: Tightly cover water storage containers (buckets, cisterns, rain barrels) so mosquitoes cannot get inside to lay eggs.
• Use Wire Mesh: For containers without lids, use wire mesh with holes smaller than an adult mosquito.
• Fill Tree Holes: Prevent tree holes from filling with water.
• Repair Septic Tanks: Repair cracks or gaps in your septic tank. Cover open vents or plumbing pipes with wire mesh.

If you find yourself in an area where mosquitoes are present, the DOH has these tips to avoid being bitten:

• Spray: Use mosquito repellant on you and your family to keep the bugs at bay.
• Arms: When outside, wear clothing that covers exposed skin, like arms and legs.
• Time: Mosquitos thrive most around dawn and dusk. Either stay indoors or be extra cautious at those times.
