CITY OF SCANDIA
November 9th, 2020
Enclosed is a summary of work done by the Metropolitan Mosquito Control District (MMCD) in the Scandia area
during the 2020 mosquito control season.
2020 was dominated by the COVID-19 pandemic and the various challenges it has caused to state and local
agencies like MMCD. We have been able to adapt our operations to allow for social distancing and other CDC
recommendations and were able to maintain our inspections and mosquito control work with limited interruption.
Throughout the season District Staff inspected almost 75,000 breeding sites for mosquito larvae and applied
198,678 acres worth of treatments which is less than the 213,800 in 2019, but more than the 183,000 acres treated
in 2018. We also treated 290,126 catch basins in the seven -county metro, which is more than any previous year.
Fortunately, there were few mosquito -borne disease cases reported in 2020 in Minnesota. The Minnesota
Department of Health (MDH) reported zero cases of West Nile virus as of November 3rd, which would make 2020
the first year with no human cases since the disease was first discovered in the state in 2002. Eastern Equine
encephalitis (EEE) is a growing concern in Minnesota with two positive cases found in deceased horses in Aitkin
and Benton counties. There were no human cases of EEE in Minnesota. In addition to monitoring and controlling
vector mosquitoes, MMCD staff also monitor the distribution of ticks capable of transmitting disease, and work
with MDH to provide information designed to reduce the risk of tick transmitted diseases.
MMCD employees controlled immature black flies (biting gnats) in small steams and large rivers throughout the
metropolitan area. In 2020, 101 black fly larvicide treatments were made to the rivers and streams in the District,
more than the 68 treatments completed in 2019. Unlike in 2019, when high river flows delayed treatments
significantly, river flows in 2020 remained at normal levels allowing for treatments to be made throughout the
season. In May, high adult black fly populations of a small stream species occurred resulting in increased customer
calls from certain areas of the District. Adult black fly abundance returned to more tolerable levels after May. We
plan to investigate the source of these high adult black fly populations and work towards a solution for 2021.
Educating the public is a key objective of MMCD and with limitations placed on us by the COVID-19 pandemic, we
adapted by producing several informational videos on our website and social media channels. We encourage you to
tell your residents to check them out at MMCD.org. We hope to be back at parades, county fairs, and other
community events in 2021!
If you have any questions, or would like to meet to discuss our agency's activities, please contact me.
Sincerely,
Stephen A. Manweiler, Executive Director

LARVAL CONTROL
The majority of control done by MMCD targets mosquitoes during
their larval stage. Mosquito larvae usually develop in standing
water and are most common after a rainfall. Larval control
materials are applied via helicopter, backpack, or by hand.
Larval Control in Scandia in 2020:
Sites Inspected: 77 1 Acres Treated: 8.30
ADULT CONTROL
MMCD supplements our larval control program with limited adult
mosquito control. Adult control materials are applied via backpack
during the day or truck -mounted cold fogger in the evening.
Adult Mosquito Control in Scandia in 2020:
Sites Inspected: 183 I Acres Treated: 1258.06
DISEASE PREVENTION
Controlling the mosquito species that are most likely to spread
disease is a top priority for MMCD. Removing containers that
could hold stagnant water is critical to reducing the spread.
Disease Prevention Activity in Scandia:
Tires Removed: 167 1 Catch Basins Treated: 0
Disease Prevention Property Inspections: 12
We encourage residents of the district to call MMCD to report mosquito annoyance, employee or
helicopter concerns, request waste tire removal, or for anything else.
Customer Calls from Scandia in 2020: 35
