Cabarrus Health Alliance staff demonstrate mosquito surveillance, say larvae will be treated with BTI
Summary
Breanna, an environmental health specialist, and Sarah Wigren, an environmental health intern, sampled standing water at McGee Park, described larval dipping and said they can treat larvae with BTI; they also described light and CO2 traps used to collect adults.
Breanna, an environmental health specialist at Cabarrus Health Alliance, and Sarah Wigren, an environmental health intern, conducted a mosquito-monitoring demonstration at McGee Park, testing standing water for larvae and deploying traps to collect adult mosquitoes.
Breanna said field staff dip a small cup into standing water to check for larvae and, "If we find any larvae, we can treat with our BTI. So, that's our larvicide. It's a bacteria that the larvae eat." The demonstration also showed a light trap and a CO2-based trap (using dry ice) to attract and collect adult mosquitoes for identification.
The presenters described the purpose as identifying local breeding sites and species so staff can target treatments. The recording did not specify how often traps will be monitored, how collected specimens are processed, or whether the public will receive treatment notices for specific properties.
Sarah Wigren identified herself as "the environmental health intern for Cabarrus Health Alliance for the summer," and did not give additional operational details during the recorded segment.
