During routine inspection, biorational or chemical control products are used to eliminate vector breeding when necessary. The following definitions apply to the control products that the District utilizes:

Larvicides:
are products that kill pest insects in their immature stages. Larvicides are highly selective and have little or no effect on non-target organisms when used according to product labels.

Adulticides:
are products that kill pest insects in their mature stages. Adulticides are only used when all other methods have been tried and public health is still threatened.
