Mosquito Control

The Louisville Metro Department of Public Health and Wellness uses a scientific approach to control mosquito populations in our area called Integrated Mosquito Management (IMM). Surveillance, source reduction, biological controls, larvaciding (eliminating mosquito larvae) and adulticiding (eliminating adult mosquitoes) are methods we use to reduce the mosquito population in Jefferson County.

Did you know...

  • Draining water from containers around your yard is the most effective way to reduce mosquitoes.
  • Fogging missions are scheduled on a case by case basis after evaluating a number of factors that include disease presence, mosquito population density, and special human population considerations

  • Bats will eat mosquitoes but really prefer other larger flying insects instead.
  • Bug zappers actually attract mosquitoes to your yard.
  • Citronella candles and mosquito plants do NOT deter mosquitoes!
  • Mosquitoes are attracted to sweat and lactic acid that is given off when you exercise.
  • Mosquitoes are attracted to CO2, which is the air you breathe out.
  • People who wear lighter colored clothing get bitten less than those who wear darker clothing.
  • Only female mosquitoes bite.
  • There are 52 mosquito species in Jefferson County. Not all mosquitoes bite people.

It starts with you. You can do many things to protect your family from mosquitoes. Remember the 3 D's: Drain, Defend, Dress.

DRAIN: Drain containers that hold water in and around your yard. By removing water, you eliminate places where mosquitoes lay their eggs.

  • Gutters- Remove leaves and debris.
  • Flowerpots- Pour out water from trays.
  • Grill Cover- Ensure water doesn’t pool on top.
  • Baby pool- Empty water every 7 days.
  • Birdbath- Change water each week.
  • Leaky faucets- Repair any leaks in faucets, hoses, or spigots.
  • Tires- Drill holes in tire swings to allow water to drain.
  • Trash cans- Keep lids on tightly. Drill holes in the bottom to allow for water to drain.
  • Containers- Remove water collecting in buckets and toys.
  • Ponds- Keep pools and ponds adequately treated.

Defend: Wear EPA approved insect repellent that contains Deet, Oil of Lemon Eucalyptus, IR3535, or Picaridin. Always follow the instructions on the product label.

Dress:  Wear long sleeves and pants, closed toe shoes, and avoid perfumes and scented lotions.







Other things you can do:

  • Place a fan out doors when sitting on your porch. Mosquitoes are poor flyers and cannot fly against heavy winds.
  • Maintain lawns by trimming hedges, keeping grass cut and removing heavy vegetation. Mosquitoes like hanging out in shady spots and places where vegetation is thick.
  • Keep grass clippings and leaves out of storm drains and catch basins. As the grass breaks down,   the mosquito larvae feed on the organinc material.
  • Clean out your ditch to keep water flowing. Stagnant water creates a perfect place for mosquitoes to lay their eggs.
  • Repair or replace your window and door screens.
  • If you can't remove standing water, use mosquito dunks found at most hardward stores.

Mosquito Education Program

Educating the public is important in the elimination of mosquito breeding habitats. Knowledge of mosquito biology, the mosquito life cycle and how mosquitoes spread disease is key to a successful program. This approach is used to reduce mosquito borne disease, such as West Nile Virus, and to maintain a quality environment for all Jefferson County residents. We offer presentations and education about mosquitoes to schools, civic groups, community organizations, and youth groups. Please contact (502) 574-6650 to schedule for a LMPHW Mosquito Control representative to visit you today.
