Mosquito Prevention Tips



Mosquitoes lay eggs in still water, which hatch in 7 to 10 days. If standing water is eliminated weekly, many mosquitoes will be kept from breeding in the first place. With fewer mosquitoes, you can have more fun in your yard. Here are some things you can do:

  • Remove standing water in ponds, ditches, clogged rain gutters, flowerpots, plant saucers, puddles, buckets, garden equipment, cans, toys, pool covers, tarps, plastic sheeting, boats, and trash.
  • Avoid mosquitoes by staying indoors at dawn and dusk when they are most active.
  • Wear long-sleeved shirts and long pants while outdoors.
  • Apply insect repellent that contains DEET. Use only 10% DEET on children, and make sure everyone washes their hands well so they do not get any repellent in their eyes or mouth. Follow directions carefully

Insect Repellent Use and Safety

How does the Health Department control mosquitoes?

The Hamilton County Health Department is responsible for mosquito-borne disease prevention. This is accomplished through an integrated mosquito management program.

1. Vector and disease surveillance
2. Source reduction
3. Control of mosquito larvae and pupae
4. Control of adult mosquitoes
5. Resistance testing
6. Public education 

Staff are certified applicators and use all pesticides in accordance with the Office of the Indiana State Chemist.

What you need to know about mosquito truck spraying

West Nile Virus


Adult mosquitoes are routinely collected and tested for West Nile Virus (WNV) in Hamilton County. Truck mounted spraying will take place only when mosquitoes test positive for West Nile Virus. Spraying will begin at sunset and cover a buffer area of approximately 1 mile around the area that tested positive. Truck mounted spraying is not done for nuisance mosquitoes and is not harmful to humans or pets. West Nile Virus activity peaks in August and September so make sure you're protected.

Zika Virus



PLEASE, Go to the CDC website for the latest CDC Zika Virus information.
