Spraying for mosquitos begins May 29

The Maryland Department of Agriculture Mosquito Control program will be spraying for mosquitos in the Town of Edmonston on Tuesday nights beginning May 29th.


Spraying may commence as soon as it is dark. As a precaution, we advise residents to stay inside their homes and close their windows while the spray truck is in the vicinity, bring in any pets, and remain in the home for 20-30 minutes after the spray truck has passed by. If there are people outside when the truck passes by, no spray will be released, and the truck will not make another pass down that street.

Spray Season

Spray season begins on May 29th and is anticipated to end on September 17th. Spraying will begin after dark and may continue until midnight or later. We do not conduct spray activity during daylight hours. If you see a truck in your community spraying during the day, it is not the State of Maryland. 

Spray Schedule

The spray schedule will rotate every 3 weeks. This means that your community may or may not be sprayed each week. The frequency will be determined by surveillance data collected, and complaints received.

In order to determine if your community will be sprayed on its scheduled spray night, please contact our office on Tuesday\’s between 2-4 pm to find out if we are spraying your community that night. We do not know any further in advance if you will be sprayed on any particular Tuesday night.

You may call 301-422-5080 or email stormy.keyes@maryland.gov.
