Iroquois County Seal

As warm weather approaches so does mosquito season. In Illinois, mosquito season begins at the start of summer and lasts into the fall.

Mosquito bites are not only irritating and itchy, they are also capable of spreading viruses that can cause illness, and in rare cases, death. The Iroquois County Public Health Department would like to provide some tips for keeping you safe.

Some tips for mosquito bite prevention are as follows:

  • Use insect repellant: EPA registered insect repellants are proven to be safe and effective when used as directed. Examples of EPA registered repellants include, but are not limited to, those that use DEET, Picaridin, and Oil of Lemon Eucalyptus (OLE).
  • Properly cover yourself while outside: Wearing a long-sleeved shirt and long pants will limit the amount of exposed skin for mosquitos to bite.
  • Stay inside during times of high activity: Mosquitos that carry West Nile Virus are most active during dusk.
  • Keeping mosquitos outside: Properly screened windows and doors, as well as the use of air conditioning, will deter mosquitos from entering your home.
  • Remove mosquito habitats: Mosquitos like to live in areas with standing water. Be sure to empty things that could hold water such as buckets. Also, keep water fresh in bird baths and fountains, and make sure swimming pools are treated and circulating.
