The Products We Use…

The Central Mass. Mosquito Control Project uses several different products and/or formulations for biological/physical/chemical mosquito control as part of an Integrated Pest Management (IPM) program. Many factors were involved in choosing these products; environmental concerns, public opinion, cost analysis, and product efficacy. We feel these products present the lowest risk to the public at large and non-target species that are on the market today while maintaining good control against mosquitoes. The links below will explain each product in use by CMMCP; product labels and MSDS sheets are included at each link.


Biological products (“biopesticides”):

Bti (Bacillus thuringiensis israelensis) – a naturally occurring, non-reproducing bacterium (used in wetlands or artificial containers)

Bsph (Bacillus sphaericus) – a naturally occurring, non-reproducing bacterium (used in abandoned swimming pools, catch basins, areas with high organic content)

Combination Bti/Bsph – new formulations using the benefits of each bacteria in a slow release manner (briquet or granule, used in catch basins or abandoned swimming pools))

Spinosad (Saccharopolyspora spinosa) – a naturally occurring, non-reproducing bacterium (used in wetlandsfield trials only to date)

Growth regulators:

Methoprene – an insect growth regulator (IGR) used against mosquito larvae (used in catch basins)



BVA® 2 mosquito oil – a highly refined oil used for control of mosquito pupae (used in wetlands or artificial containers).


Ultra-low volume (ULV) products:

Anvil® 10+10 (sumithrin or d-phenothrin) – used for ULV applications

Zenivex® E4 (etofenprox) – used for ULV applications

Barrier spray products:

Barrier spraying has only been done on a limited basis in the CMMCP area (2012 in Westboro). For information on these products please contact Tim Deschamps at

Anvil® and Zenivex® are synthetic pyrethroids (pyrethrums are found in chrysanthemums, and pyrethroids are a synthetic copy of pyrethrums, and have a lower risk to humans and other non-target organisms).

Some common pyrethroid products use by consumers include pesticides for common household pests such as ants and wasps; flea and tick shampoos/collars for pets; lice and scabies treatments (shampoos, etc.) for humans; insect repellent clothing, etc.
