Spraying ensues after West Nile found in buzzing pests

The 4 D's of West Nile Virus prevention should be followed to reduce the chance of mosquito bites. "With planning and careful effort, West Nile infection can often be prevented", said Rick Dawson, Senior Manager of Surveillance and Investigation. While mosquitoes found in Montana are unable to transmit other diseases like Zika virus, they are able to transmit WNV. Instead, people must "fight the bite" to help prevent infection. To prevent mosquito bites, wear long sleeves and long trousers when out from dusk until dawn, when mosquitoes are most active.

When outdoors, residents are advised to use repellents containing DEET, permethrin, picaridin or oil of lemon eucalyptus.


If going outside, use an EPA-approved insect repellent.

The province said it's also a good idea to secure doors and windows with well-fitting screens and to ensure no standing water accumulates on your property.


"Repellent works well when you dress in long sleeves and trousers". An increase of this magnitude indicates that it may be an especially high-risk year for West Nile Virus. To track the virus in the Pacific Northwest or get additional information, visit the DOH website at https://www.doh.wa.gov/DataandStatisticalReports/DiseasesandChronicConditions/WestNileVirus. West Nile virus has been reported in people ranging from nine months to 94 years old, but more severe disease is likely in individuals over 50 years of age, or those with weak immune systems. Up to 20 percent of people will have mild symptoms that include flu-like symptoms, swollen glands, or a skin rash on the stomach, back, and neck.

Three residents were diagnosed and hospitalized due to West Nile infections a year ago. If someone develops any of the symptoms listed above, they should see their healthcare provider for evaluation and care.
