Vector control is any method to limit or eradicate the mammals, birds, arthropods, or insects which transmit disease pathogens.
The most frequent type of vector control is mosquito control using a variety of strategies, four of which are:
1. Habitat control: stagnant water is avoided, by removal of old tires, empty cans etc., and better management of used water.
2. Insecticides, spread over mosquito breeding zones, sprayed in houses, or impregnated in bednets.
3. Introduction of sterilized male mosquitoes, in order to reduce the breeding rate.
This program enforces state laws and rules pertaining to sewage treatment and disposal and ensures that drinking water supplies are potable in order to prevent the spread of communicable diseases. This is done by an annual inspection of migrant housing facilities and reporting to the N.C. Department of Labor.
