Local tick habitat

Chester is 78% natural land cover (55% forest, plus open and brushy areas) across its 5.77 sq mi, home to about 6,732 people. That makes it the 3rd-most wooded of the 14 towns in Randolph County. Deer ticks live in wooded areas, along trail edges, and in tall grass: the more of that a town has, the more places ticks can quest.

Tick control in Chester, IL

Do I need tick control in Chester?

Tick activity in Chester is moderate today (48/100). Ticks are out, especially along yard edges, leaf litter, and shady borders. A seasonal treatment plan keeps numbers down before peak weeks hit.

Professional tick control in Chester typically means a barrier treatment along the lawn edge, leaf litter, stone walls, and shady borders where ticks wait for a host, applied two to four times a season by a licensed pest control company. It is the single most effective way to cut tick numbers in the part of the yard your family actually uses.

How much does tick control cost in Chester?

Most homeowners pay about $100 to $200 per visit for professional tick spraying, or roughly $350 to $600 for a full season of barrier treatments, depending on lot size and how wooded the property is. Quotes are free, so it costs nothing to get a real number for your yard.
