    • Locate and remove all sources of standing water, including clogged gutters/spouts, play equipment, irrigation boxes, poorly drained turf, clogged drains, holes in trees, etc.
    • In areas of standing water that can’t be drained, a product known as “mosquito dunks,” containing a bacteria toxic to mosquito larvae, can be used.
    • Keep screens in good repair to prevent adult mosquitos from entering a building.
    • Avoid outside activity when mosquitos are active (dawn and dusk).
    • Wear long-sleeved shirts, long pants and a hat.
    • Use repellants such as DEET, Picaridin, oil of lemon eucalyptus or IR3535.
