City of Ennis Department of Health Services
Our department utilizes an Integrated Mosquito Management (IMM) approach to reduce the mosquito population. IMM uses a combination of methods to prevent and control both nuisance mosquitoes and mosquitoes that spread viruses like West Nile, The basic components of IMM include source reduction, surveillance, control of all mosquito life stages, as well as community outreach and public education.
Source reduction is by far the most effective and least expensive way to reduce the mosquito population in your area. This can be achieved by eliminating standing water on your property.
Our staff actively traps for mosquitoes from May through October every year. Each week, eight traps are placed throughout the city and sent to the Texas Department of State Health Services laboratory where they are quantified and tested for vector-borne diseases like West Nile. The data we receive helps us determine if, where, or when enhanced control measures are needed to manage the mosquito population.
Control of Mosquito Life Stages
Larviciding is extremely effective in reducing the mosquito population when source reduction is not an option. Our list of current larvicides include:
Adulticiding, or spraying, only occurs once our department receives notification from the state lab of a positive mosquito trap or human case of West Nile Virus. More information about spraying can be found here.
The current adulticide used is Aqualuer 20-20.pdf.
Protect Yourselves By:
1) Drain standing water around your property.
2) Wear long sleeves and pants.
3) Wear repellent when outdoors - DEET.
4) Reduce outdoor exposure when possible.
