Question from Janice Tower: If it is occupied property, do you go on the premises to confirm larva in the stagnant pool or in containers?
Answer: Yes, if occupied we ask the tenant or landlord for permission, if it is not granted we go back with law enforcement
Question from Celestine Raineri: According to law in NC if we have a complaint we only have the right to go to the front door following "what appears to be the most used/direct path". We cannot investigate further without consent of the resident/owner. What is the best way that the sanitary nuisance investigator gets onto the entire property to investigate if no contact has been made with the resident or if consent has been denied?
Answer: If you have an environmental review board or the ability to increase authority locally, that may be an option. Our authority does not stop at the front yard but you may be able to use the emergency powers action when declared by your governor, check with your legal office to confirm.
Question from Ken McPherson, EPA R6: What vector surveillance activities do you conduct if a human case of Zika or other disease is reported (imported or locally acquired)?
Answer: (These are interim guidance at this time and is subject to change)
The mosquito control response for imported CONFIRMED cases of Zika:
1. Perform additional neighborhood inspection (500 yards around case’s home) to eliminate larval habitats.
2. Treat with long-lasting larvicide any water-holding containers that cannot be dumped, covered, discarded or otherwise modified.
3. Treat the area within 500 yards around a case’s home with ULV adulticide for three nights.
4. Provide residual insecticide treatments; repeat as necessary to reduce vector abundance.
5. Set BG Sentinel traps to determine Aedes aegypti and Ae. albopictus populations.
6. If trap has collected any Ae. aegypti or Ae. albopictus, respray the area for three consecutive nights.
7. Repeat until BG Sentinel traps collect no Ae. aegypti or Ae. albopictus.
The mosquito control response for locally acquired CONFIRMED cases of Zika (none so far!!):
1. Perform additional neighborhood inspection (minimum 500 yards around case’s home) to eliminate larval habitats with assistance from the Department of Health.
2. Treat with long-lasting larvicide any water-holding containers that cannot be dumped, covered, discarded or otherwise modified.
3. Treat the area at least 500 yards around a case’s home with ULV adulticide for three nights.
4. Provide residual insecticide treatments; repeat as necessary to reduce vector abundance.
5. Set BG Sentinel traps to determine Ae. aegypti and Ae. albopictus populations.
6. If trap has collected any Aedes aegypti or Ae. albopictus, respray the area for three consecutive nights.
7. Repeat until BG Sentinel traps collect no Ae. aegypti or Ae. albopictus.
Question from Kristen Wenrich: are any of the health departments doing education with pregnant women?
Answer: We do education with our internal providers (Family Planning and Prenatal Health Department) as well as external providers via BLASTfax (faxing guidance from State Office for OBGYN providers) and working with our ICPs from local hospital systems.
Question from Susan Welch: what chemical is used as larvicide?
Answer: We use Temephos. Its chemical family is organophosphate. Manufacturer is Clarke Mosquito Control Products (630) 894-2000. The trade name is Abate 4-E Insecticide.
Question from Gina Miranda-Diaz: how did you obtain funding for Mosquito protection "kits?"
Answer: As discussed in my presentation, the Zika kits were developed in another Texas County. While I did not mention them by name, the developer of the Zika Kit concept is Tarrant County Public Health. Tarrant County shared their concept with the rest of the State of Texas. I am not 100% certain of the funding source, but I believe it is be Public Health Emergency Preparedness (PHEP) funding from the Texas Department of State Health Services. Tarrant County Public Health can be contacted at (817) 321-4700.
Question from Dave: Did Shaun call the large bodies of water "Playas"?
Answer: Yes, I believe Playas is the correct term. Discover more here: https://tshaonline.org/handbook/online/articles/rop07

Question from Josh Willis: For Shaun: Are you experiencing any resistance to chemicals? Such as pests with crops?
Answer: No, we have not seen significant evidence of resistance yet. We do expect to see resistance shortly. We plan to change up our chemicals after the 2016 season.
Question from Ken McPherson, EPA R6: Shaun...how are you focusing your preseason efforts for Ae aegypti, since they tend breed in containers versus drainage systems?
Answer: Public awareness campaigns and increase adulticide in densely populated area, particularly in low SES neighborhoods.
Question from Ryan Tekac: What larvacidal product are you using and what is the duration or time that it will treat for?
Answer: We use Temephos. Its chemical family is organophosphate. Manufacturer is Clarke Mosquito Control Products (630) 894-2000. The trade name is Abate 4-E Insecticide. My understanding is that is good for 7 days. We do not spray in the same place until 7 days later unless the mosquito population dictates that it is necessary to do so.
Question from Kristen Wenrich: are any of the health departments doing education with pregnant women?
Answer: We are now specifically targeting pregnant women with our prevention messaging where we have not done so in the past.
