Mosquito Control in Pennsylvania DEP West Nile Virus Control Program service area, Pennsylvania — Free Help & Local Info
DEP Vector Management coordinates county mosquito surveillance and control. The public page says DEP works with representatives from 50 high-risk counties and, in another sentence, that the surveillance network covers 38 counties. A July 2026 Commonwealth West Nile plan says 47 counties had active surveillance and control programs in the 2026 season. Those figures disagree; county rows below are the NPIC roster, not a reconciliation of the three counts. The HTML page fetched showed no phone. A plan PDF names Matt Helwig at 717-346-8243 as primary contact; that direct line is not used as the public program phone. The county-coordinator lookup on the DEP site returned no results in this pass. Larval and adult control are part of the described integrated program. Inspection, fish, and a working public spray-notice tool were not confirmed. Black fly suppression is a separate DEP program and is not listed.

What they will and won't do
Public education and removing standing water are common parts of mosquito programs. Larval control may target public water, ditches and catch basins. Adult mosquito treatment follows local program criteria; a complaint is not a promise of spraying. Inspection eligibility, fish availability, pickup or delivery, response times and seasons vary. Public programs generally do not provide routine yard spraying or event protection on demand. Confirm your address with the agency: ZIP codes and county names do not establish district coverage.
