How is an area selected to be treated for adult mosquito?
Each week, our lab sets over 400 traps across the district, with each trap linked to a specific location. Here’s how it works:
- Collecting Mosquitoes: We bring all the mosquitoes from the traps to our lab.
- Sorting and Counting: The mosquitoes are sorted and counted to see how many there are.
- Testing for Disease: We test the mosquitoes to check for diseases.
- Finding Problem Areas: The results help us find where mosquito numbers and disease risk are the highest.
- Targeted Treatments: When mosquito numbers are high and disease is found, we treat those neighborhoods.
This helps us focus on the areas with the biggest problems.
Once all the results are in, our control team reviews the locations and mosquito numbers. Here’s what happens next:
- Inspections: Technicians are sent out to check for water sources near the traps with high numbers. These water sources can breed mosquitoes.
- Handling Water Sources:
- If the source is small, they will dump the water or flip the container.
- If the water can’t be drained, they will treat it to stop mosquitoes from breeding.
- Tracking: All water sources are recorded in our database and checked regularly until the problem is fixed or removed.
- Common Sources: Water can collect in places like parks, gutters, yard drains, neglected pools, ponding basins, or even containers in backyards.
This process happens alongside adult mosquito treatments if the area has high mosquito numbers and disease risk.
