Mosquito Spraying Schedule Summer 2020

From the Maryland Department of Agriculture regarding mosquito spraying for the Crofton Valley community:

  • Due to COVID-19, the State of Maryland agencies are under a hiring freeze. We, therefore, have a very limited field staff. We are able to perform very limited larviciding activities. In June we will begin our population and disease monitoring program. Unless the hiring freeze is lifted, ULV fogging for adult mosquitoes will be limited to disease case response and exceptionally high population density of adults, to be determined on a case by case basis.
  • Your Community’s assigned fog night is: Tuesday
    • Your community will only ever be fogged on Tuesday nights during the 2020 season, except possibly in case of disease response.
  • Fogging can occur anytime between 7:00 PM and 2:30 AM
    • The fog program will begin on June 3.
    • Fogging will not begin until the community has been notified and we have received the Community Notification Verification Form.
    • October 6 is the estimated last day of fogging for 2020.
  • Residents who do not wish their property to be fogged may file an exemption. The exemption policy and form can be found on our website:
