THE BUZZ

Volume 5, 12   (Week 26)

June 29, 2006

 
Mosquito Activity (Scale from 0 to 5)
  • Rain, Rain, and more Rain summarize this week. We received 1 to 2 inches of rain last week and up to 3 inches of rain earlier this week. This will cause an increase in the mosquitoes over the next two weeks.
  • Mosquito activity is a 2 for most of the city. We still have some problem areas on the city’s margins where mosquito numbers are significantly higher.
  • After a major rain event, container breeding mosquito numbers are likely to greatly increase due to flooded containers. It is extremely important to remember to dump containers at least once a week.
Surveillance
  • 10 CDC style light traps were set this week, a total of 1,525 mosquitoes were caught, for an average of 152 per trap. The traps this week were almost the same as last week. Trap counts are forecast to increase over the next two weeks due to the amount of rain.
  • 7 Gravid style traps were set this week, a total of 29 mosquitoes were caught, for an average of 4 per trap. Gravid mosquito trap numbers are still low for the entire city.
  • Mosquito breeding this week includes containers (birdbaths, flowerpots, clogged rain gutters and drains, buckets, tarps, etc.), roadside ditches, tire ruts, ground depressions are all breeding.
Service Requests
  • We received a few complaint calls this week. We anticipate calls to increase as container breeding mosquitoes become more of a problem for residents.
Control
  • Crews have worked hard to treat standing water throughout the city from the heavy rains. This includes roadside ditches, catch basins, and any other depressions which can hold enough water to breed mosquitoes.
  • Adult spray operations are being conducted as weather conditions permit. Remember, Mosquito Truck Fogging can only be conducted when winds are less than 10 miles per hour and there is no rain. If your neighborhood gets rained out, we will reschedule the spraying for the next night.
  • Mosquito Spraying information is posted on the Mosquito Spray Hotline at 393-8666.
