Mosquito Control Efforts

The City of East Chicago Health Department Animal Control Division monitors the mosquito population on a weekly basis from June through September annually. This is done by surveying large areas of standing water for mosquito larva. If these large areas of water are found to be active, mosquito larvae are treated using Natular Briquets. Natular Briquets are an insect growth inhibitor that interferes with the normal life cycle of the mosquito preventing the development of adult mosquitos from larvae.

Beginning mid-May, the Health Department Animal Control Division will begin to monitor for adult mosquitos. In these areas where excessive mosquito populations are discovered, trucks are dispatched to spray, using Biomist pesticide, which is less toxic and used for the adult mosquito control during times mosquitos are most active. As part of the mosquito control program, employees also trap and test adult mosquitos for disease.

Tips to reduce Mosquito-borne diseases

As the weather continues to be warm please be wary of mosquito populations. Follow the tips listed below to help in reducing the mosquito population and avoid mosquito-borne diseases.

  • Avoid being outdoors when mosquitoes are active (especially late afternoon, dusk to dawn and early morning)
  • Apply an EPA-registered insect repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus or paramenthane-diol to clothes and exposed skin.
  • Install or repair window and door screens so that mosquitos cannot get indoors.
  • Keep gutters clean and free of standing water.
  • Keep grass cut short and shrubbery trimmed.
  • Empty water from flower pots, pet food, water dishes, birdbaths, swimming pool covers, buckets, barrels, and cans at least twice a week.
  • Be sure to check for containers or trash in places that may be hard to see, such as under bushes around your home.

The City of East Chicago Health Department Animal Control Division conducts this program because mosquitos are known to carry diseases such as encephalitis, malaria, Zika, and the West Nile Virus.
