Products

The NCMCD uses larvicide (to target immature mosquitoes) and adulticide (to target flying adults) products to control mosquito populations and vector-borne diseases such as West Nile virus and Eastern Equine Encephalitis.

Larvicide

The larvicide products used include Bacillus thuringiensis israelensis (Bti) and Bacillus sphaericus (Bs). Bti and Bs are naturally occurring organic microbes found in soil and offer the most environmentally friendly method of mosquito control as they are very effective against mosquitoes but have extremely few non-target effects.

Fourstar Briquets (active ingredients: Bti and Bs; Label, SDS)

Methoprene is a synthetic juvenile growth hormone, an exact mimic of hormones which are naturally in the insects themselves. When applied to water where larvae are present, it prevents mosquito larvae from metamorphosing into adults.

Pupacide

When mosquitoes reach the non-feeding pupal stage, larvicidal products will no longer have any effect. We selectively use CocoBear when large amounts of pupae are present. It works by clogging the pupae’s breathing tubes.

Adulticide

The adulticide currently used by the NCMCD for area-wide ULV application is Zenivex (Label, SDS). It is applied by a truck mounted aerosol sprayer. The active ingredient is etofenprox. It is a synthetic pyrethroid which mimics pyrethrum, a naturally derived plant chemical from the chrysanthemum flower. The EPA lists Zenivex as a “reduced Risk” Product. Zenivex is approximately 200 times less acutely toxic to mammals than caffeine.

 Available for municipal properties, a perimeter barrier treatment product, Mavrik (Label, SDS), is used. It is a synthetic pyrethroid that, once applied, provides a residual effect that may last a couple of weeks. It works by killing mosquitoes that land on treated surfaces of perimeter vegetation. Once dried, this product is non-toxic to honeybees.
