    What to Do Before Hiring A For Profit Mosquito Control Service

    Contact the NSMAD, we will inspect the area of concern for FREE, and:

    • identify if there are mosquitoes present (there are several harmless lookalikes)
    • look for breeding sources and potential breeding sources
    • eliminate or treat any breeding sources with mosquito specific bio-rational control products to prevent further adult mosquito emergence
    • make recommendations that will help you minimize future mosquito issues

    Please click here to initiate a service request or if you prefer, call us at 847-446-9434.

    Contacting us first is cost effective, better for the environment, and will help minimize pesticide resistance in mosquitoes and preserve adult mosquito control products for when they are truly needed to prevent future disease outbreaks.

  • Operations Update

    June 1, 2021

    NSMAD Operations and COVID-19 The North Shore Mosquito Abatement District (NSMAD) is an essential public health agency committed to serving our communities by reducing the risk of West Nile virus and other potential mosquito-borne illnesses. To ensure that our staff and the public are protected while we continue to meet our mission during the COVID-19 pandemic, we ask for the public’s cooperation when interacting with our staff.

    Larval Control Operations

    • Regular site inspections and larval control treatments on public and private property have begun and will continue.
    • The NSMAD will continue to respond to service requests, biting mosquito complaints, as well as, abandoned pools, backyard basins, and other potential sources of mosquito breeding.
    • If you have previously made a service request regarding catch basins on your property, it is entered in our operations software system and will be addressed automatically again this year when our catch basin treatments begin around mid-May.

    How The Public Can Help

    • When making a service request, we are asking the public to help minimize direct contact with NSMAD staff as they perform their duties.
    • If you have contacted us regarding a mosquito-related issue, please allow NSMAD staff unhindered access to the potential mosquito source to conduct inspections and any necessary mosquito control treatment.
    • Tip and toss anything that can hold water that mosquitoes could breed in. A bit of work around your yard now can prevent mosquitoes from breeding on your property for years to come, and this lowers everyone’s risk.

    What to Expect From Us

    • Our staff wear identifiable uniforms that have been issued by the NSMAD and are required to have their NSMAD issued photo ID badge visible when responding to a service request.
    • NSMAD staff has been instructed to wear a suitable face covering when directly interacting with a member of the public.
    • When working in the field, NSMAD Field Technicians are required to wear a suitable face covering (cloth mask, medical mask, N95 respirator, etc.) in accordance with state and local rules regarding such use.
    • NSMAD Vehicles are stocked with hand sanitizer and additional disinfecting materials and our staff has been instructed to use them before and after making contact with a requestor or as needed.

    If you have questions or concerns, please call (847.446.9434) or email ( us.

    As temperatures continue to warm as we move further into Spring, mosquitoes aren’t the only insects with the potential to transmit diseases. Early spring is a prime time for tick activity. Be sure to check yourself, your children and your pets for the presence of ticks.

Our Mission

The NSMAD manages local mosquito populations to:
• Reduce the risk of disease from mosquito-borne viruses.
• Minimize the negative impact mosquitoes have on the quality of life in the District.


You can help us minimize your exposure to mosquito bites by reporting standing water and excessive biting mosquito activity.
