Vector Control’s Mission is to detect and minimize vector-borne diseases, to abate mosquitoes, and to assist the public in resolving problems with rodents, wildlife, and insects of medical significance.

What’s a vector?

A vector can be a mosquito, a rat, a flea, a tick, any animal or insect that can transmit disease or cause harm to humans.

Draft Environmental Evaluation-Public Comments Submitted
 
The comments that were received from the public during the public review period for our Environmental Evaluation and during the 2012 Public Scoping period are listed in this summary document (link to the pdf version).
 
The District will produce two types of responses. The first type will be designated as master responses. These will address those issues that were repeatedly raised among the comments from multiple individuals, but which all have the same response from the District. The second type will be designated as individual responses which need more specific response than is covered in the master responses.
 
The District has received 229 individual comments. Until June 19th, 2015 questions and comments can be clarified by email to vectorinfo@deh.sccgov.org. Comments and question responses will be provided at the website on or before July 3rd, 2015. The draft document will then be reviewed in light of the comments and revised into a final version for website publication.
