City of Lander to use new mosquito spray beginning tonight

    Beginning tonight, July 1st, at around dusk, the City of Lander will begin spraying for mosquitoes using Deltaguard instead of their previous mosquito adulticide Zenivex. They have provided a link to Deltagard’s label for residents to review, as well as, a Safety Data Sheet for the product.

    Additional information about the spraying and ways to prevent West Niles provided by the City of Lander can be read below.

    Information about the spraying:


    Will spray every Wednesday night, weather permitting, around dusk

    Will spray the perimeter of town until one of these criteria are met:

    trapping shows a substantial increase in West Nile vector mosquitoes or receive a positive result for West Nile in a group of mosquitoes collected in Lander

    When one of the above criteria are met we may choose to spray all of the City for the public’s safety

    Practice the 5 D’s of West Nile Prevention:


    Dusk – avoid dusk as mosquitoes are more active during this time

    Dawn – along with dusk, avoid dawn as mosquitoes are more active during this time

    Dress – wear shoes, socks, long-sleeved shirts, and long pants when outside for extended amounts of time or during dawn or dusk. Light-colored clothing made of tightly woven materials provides the best protection.


    Drain – Drain any standing water that can be found on or near your property

    Deet – Use an insect repellent containing DEET (N,N-diethyl-m-toluamide) or picaridin (KBR 3023) if additional protection is needed. Examples of other EPA registered repellents that can be used, but may be less effective, include oil of lemon eucalyptus and IR3535. It is important to read and understand an insect repellent’s label as it contains detailed information on how to use the product correctly.
