The Moab Mosquito Abatement District (MMAD) is spraying with a pesticide named Biomist in order to control the spread of the invasive Aedes aegypti mosquitoes in the Moab area. Increased spraying is necessary in order reduce the likelihood of this mosquito from becoming established in the Moab area. The active ingredient in Biomist is permethrin.

The National Pesticide Information Center (NPIC) at Oregon State University has excellent information about the potential effects of permethrin which can be found at

Permethrin has been demonstrated to be safe for use in residential and commercial areas.  There is no data to indicate that children are more sensitive to permethrin than adults. Additionally, exposure to permethrin has not been shown to be harmful to expectant mothers, the elderly or young children. The Southeast Utah Health Department is supportive of the use of spraying permethrin in the MMAD’s effort to reduce the spread of the Aedes aegypti mosquito in our area.
