What's active right now

Deer-tick nymphs are tapering as lone-star seed ticks swarm where that tick is established. Late-summer risk stays meaningful in brushy, wooded areas. Where the lone star tick lives (coastal and southern areas), aggressive larval 'seed tick' swarms peak now.

Local tick habitat

Carterville is 81% natural land cover (46% forest, plus open and brushy areas) across its 5.3 sq mi, home to about 5,808 people. That makes it the 6th-most wooded of the 15 towns in Williamson 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.

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 Carterville?
