Control Efficacy Database:
Control efficacy is recorded in a database to allow CMMCP to gauge the effectiveness of the control products in use as well as the application amounts. Control efficacy data is limited at CMMCP due to labor constraints and other factors. All products used for larval mosquito control have been tested by the manufacturer, the EPA and other mosquito control agencies. Numerous research projects have studied the efficacy of these products, as well as adverse effects on non-target organisms.
This database includes the following information:
- District #
- Map Section
- Type of Area
- Site #
- Pre/Post Data
- Product Type
- Product Amount
- Instar Data
- Number per Dip
- Technician Name
- Larval Species
Children & Families Protection Act (CPA):
Mosquito larval control products are exempt from the CPA pre-notification process providing that Category 4 products as classified by the EPA are used. Any product labeled for larval mosquito control with a signal word of "Warning" or “Caution” is acceptable. The 3 products used by CMMCP for larval/pupae control (Bti, methoprene and mineral oil) fall under this classification. While exempt, these products must still be listed on the school’s outdoor IPM plan.
Property owners have the option under Mass. Pesticide Regulations, 333CMR 13.04, paragraph 6, subsection 1(b) to exclude their property from applications of pesticide. These areas are listed on the CMMCP “No Spray” list, and if the area is extensive a map is requested to be included with the exclusion request. This type of exclusion is uncommon in the CMMCP service area.
Catch Basin Program for Culex Control:
Beginning in May of each year, we begin to apply methoprene in area catch basins for the control of Culex mosquitoes. This species of mosquito is implicated in the amplification of WNV among the bird population and possibly to humans. This program will continue through the summer, and may be restarted in selected areas if WNV becomes endemic to an area. Many factors (time of year, weather, location, etc) will play into our response if/when WNV is confirmed in a given area. CMMCP will coordinate as much as possible with city and town public works departments to inform them of our application areas, and so they can schedule their basin cleaning accordingly.
Catch basin treatments will done in the following priority order:
- Prior Year with West Nile Virus Activity;
- Senior Centers & 55+ Housing;
- Recreational Areas;
- Schools with Integrated Pest Management;
- Industrial Areas.
