 Mosquito Spraying Schedule


No spraying is predicted during the cooler, dryer winter monthsIf there are any changes they will be posted here.  

Larviciding of active sites is ongoing year round. Spot treatments may be necessary at times.




Precision targeting "spot treatments" and intensive larviciding efforts will continue through the week. We will be augmenting adult traps for adult emergence that may occur this week. 

No arbovirus activity has been detected in sentinel chickens.

Make sure to empty your containers that hold water and vaccinate your horses and pets to prevent mosquito-transmitted diseases. Lastly, MMS advises the public to remain diligent in protecting themselves from mosquito bites by following the “5 D’s,” which are:

  • Dusk and Dawn – Avoid being outdoors when mosquitoes are biting.
  • Dress – Wear clothing that covers most of your skin.
  • Defend yourself use repellents. Repellents that contain Picaridin, DEET (N,N-diethyl-meta-toluamide, or N,N-diethyl-3-methylbenzamide).  Oil of lemon eucalyptus, IR3535 and permethrin are some repellent options.
  • Drainage – Check around your home to rid the area of standing water, which is where mosquitoes can lay their eggs.

 Mosquito Repellents


By reading and following label directions, the use of repellents can reduce or eliminate the discomfort of insect bites. Ticks can transmit serious diseases such as Lyme disease, Rocky Mountain spotted fever, and other serious diseases. Repellents also curtail the spread of such mosquito-borne diseases as St. Louis encephalitis and West Nile virus.

An updated Environmental Protection Agency (EPA) webpage serves as a one-stop-shop for information on registered repellents. It provides up-to-date listings of mosquito and tick repellents as well as tips for choosing the right product to meet your needs. For best results, use only insect repellents registered by EPA. When used according to instructions on the label, registered products have been shown to be effective. More information on insect repellent:
