ticks activity by season.

In Illinois, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure usually turns up the conditions that are letting them in.

Where ticks live.
Ticks around Illinois concentrate in Woodlands and brushy trail margins, Moist leaf litter and shaded yard edges, and Tall grass and wildlife travel corridors. Open, sunny, closely mowed lawn holds far fewer ticks than the edges do.
Making your yard less tick-friendly.
- Discourage deer and mice near the house. In this region, prioritize: Prioritize the lawn-to-woods perimeter during inspection, Keep paths and play areas away from brush, and Use current county surveillance when estimating local species presence. - Keep play sets and seating away from the edge. - Add a 3-foot wood-chip or gravel strip between lawn and woods. - Mow and rake leaf litter from high-use areas. - The highest-value steps are the cheap ones.
Tick control is three jobs.
- Protect the people and pets: repellents, tick checks, and vet-approved prevention. A quote usually covers only the second job. Ask which of the three it covers. - Treat the edges: a targeted acaricide, timed to spring and fall peaks. - Reduce the habitat: mow, rake, and create a dry barrier at the edge. - Tick control comes down to three jobs in order.
Removing a tick the right way.
