Vector Control

Vector control is the management and prevention of diseases spread through pests.  The Boone County Health Department can aid the community’s exposure to vector borne diseases such as West Nile Virus, Lyme Disease and Alpha Gal Syndrome.  Please read below to understand what the BCHD offers to the public.

Mosquito Control

The Boone County Health Department has developed a mosquito control program to reduce mosquito populations on public lands and to provide information to the citizens of Boone County. The primary focus is to control the mosquito life cycle and manage mosquito populations during larvae development.

Larviciding

Our mosquito control program involves the application of larvicide in areas of concern. Larvicide attacks the mosquitoes that are in the larvae stage and present in standing water areas. This is the most efficient and effective way of controlling mosquitoes and prevents them from becoming adult mosquitoes. All larvicides being used breakdown naturally in the environment and are approved for environmentally sensitive areas. Health Department employees are licensed by the Indiana State Chemist Office to apply pesticides for mosquito control. If you own property that is potentially a mosquito breeding habitat, you can contact the Health Department to complete an inspection.  Or you can contact a commercial exterminator for the control of mosquitoes.  For more detailed information on the larvicides we use, please contact our office at 765-483-4458.

Mosquito Collection

The Boone County Health Department traps and collects mosquitoes for West Nile Virus testing conducted by the Indiana State Department of Health.

Mosquito Facts

All mosquitoes need water in which to survive their early life stages. In Indiana they usually need 10 or more days of standing, still water. Adult flying mosquitoes frequently rest in grass, shrubbery, or other foliage, but they never develop there.  Male and female mosquitoes eat plant nectar. However, only females bite mammals for blood meals to produce eggs.
Mosquitoes lay their eggs in standing water where they hatch in a day or two. They can also lay eggs in old tires, tin cans, or other water holding containers where they remain unhatched for weeks or months until they are covered with water.

Mosquitos can carry the following diseases
• West Nile Virus
• St. Louis Encephalitis
• Lacrosse Encephalitis
• East/West Equine Encephalitis
• Dog Heartworm
• Zika Virus

Personal Protection

Boone County Health Department recommends people take the following protective steps to reduce the risk of mosquito bites:
• Avoid being outdoors during prime mosquito biting times, dusk to dawn
• Apply insect repellent containing DEET, picaridin, or oil of lemon eucalyptus to clothes and exposed skin
• Install or repair screens on windows and doors to keep mosquitoes out of the home
• When possible, wear long-sleeved shirts and pants when outside

Take the following steps to rid your properties of potential mosquito breeding grounds by:
• Discard old tires, tin cans, plastic containers, ceramic pots or other containers that can hold water
• Repair failed septic systems
• Drill holes in the bottom of recycling containers left outdoors
• Keep grass cut short and shrubbery trimmed
• Clean clogged roof gutters, particularly if leaves tend to plug up the drains
• Frequently replace the water in pet bowls
• Flush ornamental fountains and birdbaths periodically
• Aerate ornamental pools, or stock them with predatory fish

If your property holds standing water for extended periods of time, contact the Health Department for complimentary mosquito treatment.

Tick Control

Ticks are external parasites that feed off blood meals from humans and animals.  Ticks can transmit bacteria or viruses into the human body that can cause diseases such as Lyme Disease, Rocky Mountain Spotted Fever, Anaplasmosis, Tularemia, Alpha-gal Syndrome and Ehrlichiosis.

How to remove an attached tick

Graphic: Centers for Disease Control and Prevention.

• Use fine-tipped tweezers or a tick removal tool to grasp the tick as close to the skin’s surface as possible
• Pull upward with steady, even pressure. Don’t twist or jerk the tick; this can cause the mouthparts to break off and remain in the skin. If this happens, remove the mouthparts with tweezers. If you are unable to remove mouth parts easily with clean tweezers, leave the area alone and let the skin heal.
• After removing the tick, thoroughly clean the bite area and your hands with rubbing alcohol or soap and water.
• Never crush a tick with your fingers. Dispose of a live tick by putting it in alcohol, placing it in a sealed bag/container and freezing it

Below is a graphic of the most common ticks found in Indiana. Each species of ticks can carry different disease-causing pathogens or bacteria.  Nymph ticks are considered the most harmful due to their small size.  They can often be overlooked.  After going outdoors be sure to check your body and hair for ticks.
