West Nile Still a Threat In Cold Weather

FAQ's

Yes, different species of mosquitoes are active through the winter in the DFW area. Adult females will overwinter in area storm-drains, culverts, sheds, and other such protected areas.

WNV is harbored in the bird population and over 250 species of birds are reservoirs. The virus is present year round in the bird population and disease positive mosquitoes have been found as early as February in this area.

Adult mosquito treatments, or fogging, is the only way to take disease positive mosquitoes out of the air. During seasons with even moderate disease levels, adulticiding should be employed along with larvaciding efforts.

Different types of laboratory tests are used throughout the country, but data reported in Texas is confirmed by real time PCR, or RTPCR. We utilize either the Tarrant County Public Health Department laboratory or an independent third party lab to test and confirm disease in our collected mosquitoes. Both labs archive tested material so any results may be replicated if needed. Both labs provide fast results.

Really the fogging should occur when the disease is identified in the mosquito population through surveillance and disease testing. Human cases have an automatic delay of two to four weeks after exposure to allow for disease confirmation. Mosquito control programs that use confirmed human disease as the adulticide triggers are continuously behind the disease curve.

If disease presence is set as the trigger for adulticiding, Rid All has always recommended three consecutive nights of treatment. Research shows that three consecutive nights of treatment reduces both numbers of adult mosquitoes and human cases of disease.

Fogging should never start before 9:00pm. We have historically initiated fogging at 10:00pm and ended by 5:00am. Research shows peak activity hours for Culex quinquefasciatus between 12:00pm and 2:00am with host seeking mosquitoes becoming active at 10:00pm.

West Nile is a disease that will remain in the North Texas area because of the bird resevoirs. We will face West Nile every year, but we cannot predict its intensity.
