County vector control begins second round of mosquito spraying outside city limits

David, a county staff member, told the commissioners court during the public-comment period that Victoria County completed a second round of mosquito spraying for unincorporated areas and planned additional applications subject to weather constraints.

David said the spray operation targets both adult mosquitoes and larvae and that applications are limited by operational rules: sprays may be applied only when temperatures are below 90 degrees, winds are under 10 miles per hour, it is not raining and the same spot can be sprayed no more often than every 72 hours. "We only can spray if the temperature is under 90 degrees... Winds are under 10 miles an hour and as long as it's dry outside, not raining. We only can apply the spray every 3 days," David said.

He emphasized the county sprays only outside city limits and that city parks and recreation handle in-city spraying. David also said the county coordinates timing to avoid harming registered beehives by spraying later in the day when bees are less active.

Why it matters: mosquito-control operations affect public-health nuisance and vector-borne disease risk. The county described operational limits and advised residents to remove standing water, dispose of containers that hold water and maintain yards. David noted over-the-counter foggers are available for household use.

Court context: This was a staff informational update during Citizens Communication; no vote or new policy was taken at the June 23 meeting.
